Let's divide 75821256 by 86
Our goal is to divide 75821256 by 86.

Moving on to step 1:
When dividing 7 by 86, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 86

On to step 2:
When dividing 75 by 86, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 86

Step 3:
When dividing 758 by 86, we get 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 688 from 758 and we're left with 70.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 86

Advancing to step 4:
If we divide 702 by 86, we get 8 and a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we subtract 688 from 702, we get 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 86

On to step 5:
86 goes into 141 1 times with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 881.0
If we subtract 86 from 141, we get 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 86

Let's proceed to step 6:
552 divided by 86 is 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 8816.0
Subtract 516 from 552 to get 36.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 86

On to step 7:
365 divided by 86 is 4 with a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 88164.0
Subtracting 344 from 365 leaves us with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 86

Moving on to step 8:
If we divide 216 by 86, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 881642.0
Subtract 172 from 216 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
When dividing 440 by 86, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 881642.5
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
86 goes into 100 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 881642.51
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
86 goes into 140 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 881642.511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 881642.511 and a remainder of 0.0054.
