We look at the division of 99733123 by 638 
We're looking to find how many times 638 goes into 99733123.

Step 1:
638 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 638

Going ahead to step 2:
638 goes into 99 0 times with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 638

Step 3:
997 divided by 638 is 1 with a remainder of 359.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 638 from 997 to get 359.
Take the next digit (3) from the dividend and append it to 359, then repeat: 3593 / 638

On to step 4:
The number 638 fits into 3593 5 times, leaving a remainder of 403.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 3190 from 3593 and we're left with 403.
Bring next digit (3) of the dividend behind the 403 and repeat the process: 4033 / 638

Moving on to step 5:
4033 divided by 638 is 6 with a remainder of 205.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
If we take 3828 away from 4033, we end up with 205.
Append the next digit (1) from the dividend to 205 and continue with: 2051 / 638

Step 6:
If we divide 2051 by 638, we get 3 and a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 1563.0
The remainder is 137 after subtracting 1914 from 2051.
Bring next digit (2) of the dividend behind the 137 and repeat the process: 1372 / 638

Advancing to step 7:
638 can be fit into 1372 2 times, resulting in a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 15632.0
Deduct 1276 from 1372 and we're left with 96.
Include the next digit (3) from the dividend after 96, then repeat: 963 / 638

Step 8:
If we divide 963 by 638, we get 1 and a remainder of 325.
The number 1 becomes the next digit in our result. 
Result so far: 156321.0
Subtracting 638 from 963 leaves us with 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.
Write down 5 as next digit of the result. 
Result so far: 156321.5
If we take 3190 away from 3250, we end up 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:
600 divided by 638 is 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 156321.5
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 11:
638 can be fit into 6000 9 times, resulting in a remainder of 258.
Write down 9 as next digit of the result. 
Result so far: 156321.509
The remainder is 258 after subtracting 5742 from 6000.
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:
638 goes into 2580 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 156321.5094
Subtract 2552 from 2580 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
638 goes into 280 0 times with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 156321.5094
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 14:
638 can be fit into 2800 4 times, resulting in a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 156321.509404
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.

Moving on to step 15:
638 goes into 2480 3 times with a remainder of 566.
The number 3 becomes the next digit in our result. 
Result so far: 156321.5094043
If we subtract 1914 from 2480, we get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Advancing to step 16:
When dividing 5660 by 638, we get 8 with a remainder of 556.
The number 8 becomes the next digit in our result. 
Result so far: 156321.50940438
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 156321.50940438, with a leftover of 5.56e-07.
