Let's divide 86991582 by 522
We want to divide 86991582 by 522.

Moving on to step 1:
If we divide 8 by 522, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 522

Advancing to step 2:
522 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 522

Advancing to step 3:
869 divided by 522 is 1 with a remainder of 347.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 522 away from 869, we end up with 347.
Grab the next digit (9) from the dividend, add it to 347, then carry on: 3479 / 522

Step 4:
If we divide 3479 by 522, we get 6 and a remainder of 347.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 3132 from 3479, we get 347.
Include the next digit (1) from the dividend after 347, then repeat: 3471 / 522

Moving on to step 5:
522 can be fit into 3471 6 times, resulting in a remainder of 339.
Write down 6 as next digit of the result. 
Result so far: 166.0
Subtract 3132 from 3471 to get 339.
Grab the next digit (5) from the dividend, add it to 339, then carry on: 3395 / 522

Let's proceed to step 6:
522 can be fit into 3395 6 times, resulting in a remainder of 263.
The next digit of our result is 6. 
Result so far: 1666.0
If we subtract 3132 from 3395, we get 263.
Fetch the next digit (8) from the dividend, attach it to 263 and continue: 2638 / 522

Moving on to step 7:
2638 divided by 522 is 5 with a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 16665.0
Deduct 2610 from 2638 and we're left with 28.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 522

Going ahead to step 8:
When dividing 282 by 522, we get 0 with a remainder of 282.
Record the quotient 0 as the next digit in the result. 
Result so far: 166650.0
If we subtract 0 from 282, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 9:
522 can be fit into 2820 5 times, resulting in a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 166650.5
Subtracting 2610 from 2820 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
2100 divided by 522 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 166650.54
Subtract 2088 from 2100 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
The number 522 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 166650.54
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
1200 divided by 522 is 2 with a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 166650.5402
The remainder is 156 after subtracting 1044 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 13:
When dividing 1560 by 522, we get 2 with a remainder of 516.
Use 2 as the next digit of our solution. 
Result so far: 166650.54022
Subtracting 1044 from 1560 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

In conclusion, the division gives 166650.54022 with a balance of 0.000516.
