We look at the division of 809432 by 86 
Our goal is to divide 809432 by 86.

On to step 1:
The number 86 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 86

Moving on to step 2:
86 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 86

Going ahead to step 3:
86 goes into 809 9 times with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 774 from 809 and we're left with 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 86

Moving on to step 4:
86 goes into 354 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 94.0
If we take 344 away from 354, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 86

Advancing to step 5:
The number 86 fits into 103 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 941.0
Subtract 86 from 103 to get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 86

On to step 6:
If we divide 172 by 86, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 9412.0
Subtracting 172 from 172 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
When dividing 0 by 86, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9412.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
86 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9412.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 9412.0, and the remainder is 0.0.
