We're dividing 99925595 by 638 
We're looking to find how many times 638 goes into 99925595.

Moving on to step 1:
638 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 638

Let's proceed to step 2:
99 divided by 638 is 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Grab the next digit (9) from the dividend, add it to 99, then carry on: 999 / 638

Advancing to step 3:
999 divided by 638 is 1 with a remainder of 361.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 361 after subtracting 638 from 999.
Append the next digit (2) from the dividend to 361 and continue with: 3612 / 638

Advancing to step 4:
3612 divided by 638 is 5 with a remainder of 422.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 3190 from 3612 to get 422.
Grab the next digit (5) from the dividend, add it to 422, then carry on: 4225 / 638

Step 5:
The number 638 fits into 4225 6 times, leaving a remainder of 397.
Put 6 as the next digit of the answer. 
Result so far: 156.0
If we subtract 3828 from 4225, we get 397.
Grab the next digit (5) from the dividend, add it to 397, then carry on: 3975 / 638

Advancing to step 6:
When dividing 3975 by 638, we get 6 with a remainder of 147.
Write down 6 as next digit of the result. 
Result so far: 1566.0
Deduct 3828 from 3975 and we're left with 147.
Append the next digit (9) from the dividend to 147 and continue with: 1479 / 638

Let's proceed to step 7:
When dividing 1479 by 638, we get 2 with a remainder of 203.
The number 2 becomes the next digit in our result. 
Result so far: 15662.0
Deduct 1276 from 1479 and we're left with 203.
Grab the next digit (5) from the dividend, add it to 203, then carry on: 2035 / 638

Let's proceed to step 8:
When dividing 2035 by 638, we get 3 with a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 156623.0
If we take 1914 away from 2035, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 9:
When dividing 1210 by 638, we get 1 with a remainder of 572.
Write down 1 as next digit of the result. 
Result so far: 156623.1
The remainder is 572 after subtracting 638 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Going ahead to step 10:
When dividing 5720 by 638, we get 8 with a remainder of 616.
The number 8 becomes the next digit in our result. 
Result so far: 156623.18
If we take 5104 away from 5720, we end up with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 11:
When dividing 6160 by 638, we get 9 with a remainder of 418.
Put 9 as the next digit of the answer. 
Result so far: 156623.189
If we subtract 5742 from 6160, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 12:
The number 638 fits into 4180 6 times, leaving a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 156623.1896
If we subtract 3828 from 4180, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 13:
The number 638 fits into 3520 5 times, leaving a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 156623.18965
If we subtract 3190 from 3520, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 14:
The number 638 fits into 3300 5 times, leaving a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 156623.189655
Deduct 3190 from 3300 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 156623.189655 with a remainder of 1.1e-05.
