We look at the division of 21629467 by 458 
We're looking to find how many times 458 goes into 21629467.

Let's proceed to step 1:
If we divide 2 by 458, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 458

Advancing to step 2:
458 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 458

Moving on to step 3:
When dividing 216 by 458, we get 0 with a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 216, we end up with 216.
Include the next digit (2) from the dividend after 216, then repeat: 2162 / 458

Advancing to step 4:
458 can be fit into 2162 4 times, resulting in a remainder of 330.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 1832 away from 2162, we end up with 330.
Bring next digit (9) of the dividend behind the 330 and repeat the process: 3309 / 458

On to step 5:
458 can be fit into 3309 7 times, resulting in a remainder of 103.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we subtract 3206 from 3309, we get 103.
Take the next digit (4) from the dividend and append it to 103, then repeat: 1034 / 458

On to step 6:
458 goes into 1034 2 times with a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 472.0
If we take 916 away from 1034, we end up with 118.
Fetch the next digit (6) from the dividend, attach it to 118 and continue: 1186 / 458

Going ahead to step 7:
The number 458 fits into 1186 2 times, leaving a remainder of 270.
Write down 2 as next digit of the result. 
Result so far: 4722.0
Subtract 916 from 1186 to get 270.
Fetch the next digit (7) from the dividend, attach it to 270 and continue: 2707 / 458

Step 8:
The number 458 fits into 2707 5 times, leaving a remainder of 417.
Use 5 as the next digit of our solution. 
Result so far: 47225.0
Subtracting 2290 from 2707 leaves us with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Let's proceed to step 9:
The number 458 fits into 4170 9 times, leaving a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 47225.9
Subtracting 4122 from 4170 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
The number 458 fits into 480 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 47225.91
Deduct 458 from 480 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
The number 458 fits into 220 0 times, leaving a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 47225.91
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 12:
The number 458 fits into 2200 4 times, leaving a remainder of 368.
The next digit of our result is 4. 
Result so far: 47225.9104
Subtract 1832 from 2200 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 13:
If we divide 3680 by 458, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 47225.91048
Deduct 3664 from 3680 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
If we divide 160 by 458, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 47225.91048
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
When dividing 1600 by 458, we get 3 with a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 47225.9104803
The remainder is 226 after subtracting 1374 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 16:
458 can be fit into 2260 4 times, resulting in a remainder of 428.
The number 4 becomes the next digit in our result. 
Result so far: 47225.91048034
Subtracting 1832 from 2260 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

The final result is 47225.91048034 with a remainder of 4.28e-07.
