We're dividing 88896815 by 638 
Let's see how many times 638 fits into 88896815.

On to step 1:
8 divided by 638 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 638

Going ahead to step 2:
When dividing 88 by 638, we get 0 with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Append the next digit (8) from the dividend to 88 and continue with: 888 / 638

Step 3:
The number 638 fits into 888 1 times, leaving a remainder of 250.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 250 after subtracting 638 from 888.
Bring next digit (9) of the dividend behind the 250 and repeat the process: 2509 / 638

Going ahead to step 4:
When dividing 2509 by 638, we get 3 with a remainder of 595.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1914 from 2509, we get 595.
Include the next digit (6) from the dividend after 595, then repeat: 5956 / 638

Moving on to step 5:
638 can be fit into 5956 9 times, resulting in a remainder of 214.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Deduct 5742 from 5956 and we're left with 214.
Grab the next digit (8) from the dividend, add it to 214, then carry on: 2148 / 638

Moving on to step 6:
When dividing 2148 by 638, we get 3 with a remainder of 234.
Use 3 as the next digit of our solution. 
Result so far: 1393.0
Subtracting 1914 from 2148 leaves us with 234.
Take the next digit (1) from the dividend and append it to 234, then repeat: 2341 / 638

Step 7:
638 can be fit into 2341 3 times, resulting in a remainder of 427.
Write down 3 as next digit of the result. 
Result so far: 13933.0
Deduct 1914 from 2341 and we're left with 427.
Grab the next digit (5) from the dividend, add it to 427, then carry on: 4275 / 638

Moving on to step 8:
If we divide 4275 by 638, we get 6 and a remainder of 447.
Use 6 as the next digit of our solution. 
Result so far: 139336.0
The remainder is 447 after subtracting 3828 from 4275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 9:
638 goes into 4470 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 139336.7
Subtracting 4466 from 4470 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 638 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 139336.7
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 638 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 139336.7
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 139336.7 with a remaining 0.04.
