86715537 ÷ 659 
We want to divide 86715537 by 659.

Step 1:
When dividing 8 by 659, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 659

Step 2:
When dividing 86 by 659, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 659

Let's proceed to step 3:
When dividing 867 by 659, we get 1 with a remainder of 208.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 659 away from 867, we end up with 208.
Grab the next digit (1) from the dividend, add it to 208, then carry on: 2081 / 659

On to step 4:
When dividing 2081 by 659, we get 3 with a remainder of 104.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 104 after subtracting 1977 from 2081.
Fetch the next digit (5) from the dividend, attach it to 104 and continue: 1045 / 659

On to step 5:
659 can be fit into 1045 1 times, resulting in a remainder of 386.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
If we subtract 659 from 1045, we get 386.
Take the next digit (5) from the dividend and append it to 386, then repeat: 3865 / 659

Moving on to step 6:
659 can be fit into 3865 5 times, resulting in a remainder of 570.
The next digit of our result is 5. 
Result so far: 1315.0
If we take 3295 away from 3865, we end up with 570.
Include the next digit (3) from the dividend after 570, then repeat: 5703 / 659

Step 7:
5703 divided by 659 is 8 with a remainder of 431.
Record the quotient 8 as the next digit in the result. 
Result so far: 13158.0
The remainder is 431 after subtracting 5272 from 5703.
Bring next digit (7) of the dividend behind the 431 and repeat the process: 4317 / 659

Going ahead to step 8:
The number 659 fits into 4317 6 times, leaving a remainder of 363.
Use 6 as the next digit of our solution. 
Result so far: 131586.0
Deduct 3954 from 4317 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

On to step 9:
3630 divided by 659 is 5 with a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 131586.5
If we take 3295 away from 3630, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 10:
3350 divided by 659 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 131586.55
If we take 3295 away from 3350, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 131586.55 and a remainder of 0.055.
