93416923 ÷ 638 
Our goal is to divide 93416923 by 638.

Advancing to step 1:
When dividing 9 by 638, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 638

Advancing to step 2:
When dividing 93 by 638, we get 0 with a remainder of 93.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 93 and we're left with 93.
Include the next digit (4) from the dividend after 93, then repeat: 934 / 638

On to step 3:
The number 638 fits into 934 1 times, leaving a remainder of 296.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 638 from 934 to get 296.
Bring next digit (1) of the dividend behind the 296 and repeat the process: 2961 / 638

Let's proceed to step 4:
When dividing 2961 by 638, we get 4 with a remainder of 409.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 409 after subtracting 2552 from 2961.
Append the next digit (6) from the dividend to 409 and continue with: 4096 / 638

Step 5:
638 can be fit into 4096 6 times, resulting in a remainder of 268.
Use 6 as the next digit of our solution. 
Result so far: 146.0
If we subtract 3828 from 4096, we get 268.
Take the next digit (9) from the dividend and append it to 268, then repeat: 2689 / 638

Moving on to step 6:
The number 638 fits into 2689 4 times, leaving a remainder of 137.
The next digit of our result is 4. 
Result so far: 1464.0
Subtracting 2552 from 2689 leaves us with 137.
Append the next digit (2) from the dividend to 137 and continue with: 1372 / 638

On to step 7:
If we divide 1372 by 638, we get 2 and a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 14642.0
Subtracting 1276 from 1372 leaves us with 96.
Bring next digit (3) of the dividend behind the 96 and repeat the process: 963 / 638

Advancing to step 8:
963 divided by 638 is 1 with a remainder of 325.
Use 1 as the next digit of our solution. 
Result so far: 146421.0
Subtract 638 from 963 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 9:
The number 638 fits into 3250 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 146421.5
Deduct 3190 from 3250 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 638, we get 0 and a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 146421.5
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 11:
6000 divided by 638 is 9 with a remainder of 258.
Write down 9 as next digit of the result. 
Result so far: 146421.509
Subtract 5742 from 6000 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 12:
If we divide 2580 by 638, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 146421.5094
If we take 2552 away from 2580, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
638 can be fit into 280 0 times, resulting in a remainder of 280.
The next digit of our result is 0. 
Result so far: 146421.5094
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 14:
638 goes into 2800 4 times with a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 146421.509404
If we take 2552 away from 2800, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 15:
638 goes into 2480 3 times with a remainder of 566.
Use 3 as the next digit of our solution. 
Result so far: 146421.5094043
Subtracting 1914 from 2480 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Let's proceed to step 16:
5660 divided by 638 is 8 with a remainder of 556.
The number 8 becomes the next digit in our result. 
Result so far: 146421.50940438
Deduct 5104 from 5660 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

The final outcome is 146421.50940438, with a leftover of 5.56e-07.
