We divide 131638 by 8
We want to figure out the number of times 131638 can be divided by 8.

Moving on to step 1:
The number 8 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 8

On to step 2:
8 goes into 13 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 8 from 13 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 8

Moving on to step 3:
8 goes into 51 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 48 from 51 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 8

Step 4:
36 divided by 8 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 164.0
If we take 32 away from 36, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 8

Let's proceed to step 5:
The number 8 fits into 43 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 1645.0
The remainder is 3 after subtracting 40 from 43.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 8

Going ahead to step 6:
8 goes into 38 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 16454.0
Deduct 32 from 38 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
8 can be fit into 60 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 16454.7
If we take 56 away from 60, we end up 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.

Going ahead to step 8:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16454.75
Subtracting 40 from 40 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16454.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16454.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 16454.75, with a leftover of 0.0.
