Let's divide 86581083 by 525
We want to divide 86581083 by 525.

Step 1:
525 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 525

On to step 2:
If we divide 86 by 525, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 525

Advancing to step 3:
525 can be fit into 865 1 times, resulting in a remainder of 340.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 525 from 865 to get 340.
Bring next digit (8) of the dividend behind the 340 and repeat the process: 3408 / 525

Advancing to step 4:
If we divide 3408 by 525, we get 6 and a remainder of 258.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 3150 from 3408 to get 258.
Take the next digit (1) from the dividend and append it to 258, then repeat: 2581 / 525

Going ahead to step 5:
525 goes into 2581 4 times with a remainder of 481.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Subtracting 2100 from 2581 leaves us with 481.
Append the next digit (0) from the dividend to 481 and continue with: 4810 / 525

Step 6:
If we divide 4810 by 525, we get 9 and a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 1649.0
The remainder is 85 after subtracting 4725 from 4810.
Include the next digit (8) from the dividend after 85, then repeat: 858 / 525

Let's proceed to step 7:
525 goes into 858 1 times with a remainder of 333.
The next digit of our result is 1. 
Result so far: 16491.0
Deduct 525 from 858 and we're left with 333.
Grab the next digit (3) from the dividend, add it to 333, then carry on: 3333 / 525

Step 8:
If we divide 3333 by 525, we get 6 and a remainder of 183.
Record the quotient 6 as the next digit in the result. 
Result so far: 164916.0
If we take 3150 away from 3333, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 9:
When dividing 1830 by 525, we get 3 with a remainder of 255.
Put 3 as the next digit of the answer. 
Result so far: 164916.3
Deduct 1575 from 1830 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 10:
If we divide 2550 by 525, we get 4 and a remainder of 450.
Write down 4 as next digit of the result. 
Result so far: 164916.34
If we take 2100 away from 2550, we end up 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.

Moving on to step 11:
If we divide 4500 by 525, we get 8 and a remainder of 300.
Use 8 as the next digit of our solution. 
Result so far: 164916.348
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.

Let's proceed to step 12:
525 can be fit into 3000 5 times, resulting in a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 164916.3485
If we subtract 2625 from 3000, we 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.

Let's proceed to step 13:
The number 525 fits into 3750 7 times, leaving a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 164916.34857
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.

Let's proceed to step 14:
750 divided by 525 is 1 with a remainder of 225.
Use 1 as the next digit of our solution. 
Result so far: 164916.348571
Subtract 525 from 750 to 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.

Let's proceed to step 15:
When dividing 2250 by 525, we get 4 with a remainder of 150.
Write down 4 as next digit of the result. 
Result so far: 164916.3485714
The remainder is 150 after subtracting 2100 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 16:
525 goes into 1500 2 times with a remainder of 450.
The next digit of our result is 2. 
Result so far: 164916.34857142
If we take 1050 away from 1500, we end up 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.

In conclusion, the division gives 164916.34857142 with a balance of 4.5e-07.
