We're dividing 64414517 by 21 
We're looking to find how many times 21 goes into 64414517.

Let's proceed to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 21

Step 2:
If we divide 64 by 21, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 63 from 64 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 21

Moving on to step 3:
14 divided by 21 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 21

Let's proceed to step 4:
21 goes into 141 6 times with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 306.0
Subtract 126 from 141 to get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 21

Let's proceed to step 5:
21 can be fit into 154 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 3067.0
If we subtract 147 from 154, we get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 21

On to step 6:
The number 21 fits into 75 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 30673.0
Subtract 63 from 75 to get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 21

Step 7:
21 goes into 121 5 times with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 306735.0
Subtract 105 from 121 to get 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 21

On to step 8:
The number 21 fits into 167 7 times, leaving a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 3067357.0
Deduct 147 from 167 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 3067357.9
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3067357.95
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3067357.952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
If we divide 80 by 21, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3067357.9523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
The number 21 fits into 170 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 3067357.95238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 21 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 3067357.95238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 3067357.9523809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 16:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3067357.95238095
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 3067357.95238095 with a remaining 5e-09.
