We're dividing 86655231 by 525 
Our goal is to divide 86655231 by 525.

Going ahead to step 1:
525 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 525

Let's proceed to step 2:
86 divided by 525 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 525

Step 3:
When dividing 866 by 525, we get 1 with a remainder of 341.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 525 from 866 and we're left with 341.
Append the next digit (5) from the dividend to 341 and continue with: 3415 / 525

On to step 4:
The number 525 fits into 3415 6 times, leaving a remainder of 265.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 3150 from 3415, we get 265.
Bring next digit (5) of the dividend behind the 265 and repeat the process: 2655 / 525

On to step 5:
2655 divided by 525 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
If we take 2625 away from 2655, we end up with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 525

Let's proceed to step 6:
302 divided by 525 is 0 with a remainder of 302.
The next digit of our result is 0. 
Result so far: 1650.0
The remainder is 302 after subtracting 0 from 302.
Append the next digit (3) from the dividend to 302 and continue with: 3023 / 525

Moving on to step 7:
The number 525 fits into 3023 5 times, leaving a remainder of 398.
Write down 5 as next digit of the result. 
Result so far: 16505.0
Deduct 2625 from 3023 and we're left with 398.
Append the next digit (1) from the dividend to 398 and continue with: 3981 / 525

Moving on to step 8:
3981 divided by 525 is 7 with a remainder of 306.
Use 7 as the next digit of our solution. 
Result so far: 165057.0
Deduct 3675 from 3981 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 9:
When dividing 3060 by 525, we get 5 with a remainder of 435.
The number 5 becomes the next digit in our result. 
Result so far: 165057.5
Subtract 2625 from 3060 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Going ahead to step 10:
When dividing 4350 by 525, we get 8 with a remainder of 150.
Write down 8 as next digit of the result. 
Result so far: 165057.58
Subtract 4200 from 4350 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
If we divide 1500 by 525, we get 2 and a remainder of 450.
Record the quotient 2 as the next digit in the result. 
Result so far: 165057.582
Deduct 1050 from 1500 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 12:
4500 divided by 525 is 8 with a remainder of 300.
The number 8 becomes the next digit in our result. 
Result so far: 165057.5828
If we subtract 4200 from 4500, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 13:
If we divide 3000 by 525, we get 5 and a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 165057.58285
Subtract 2625 from 3000 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 14:
3750 divided by 525 is 7 with a remainder of 75.
The next digit of our result is 7. 
Result so far: 165057.582857
Subtract 3675 from 3750 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 15:
The number 525 fits into 750 1 times, leaving a remainder of 225.
Record the quotient 1 as the next digit in the result. 
Result so far: 165057.5828571
If we subtract 525 from 750, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 16:
If we divide 2250 by 525, we get 4 and a remainder of 150.
Record the quotient 4 as the next digit in the result. 
Result so far: 165057.58285714
If we take 2100 away from 2250, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 165057.58285714 with a remainder of 1.5e-07.
