We divide 177571 by 86
We want to figure out the number of times 177571 can be divided by 86.

On to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 86

Going ahead to step 2:
When dividing 17 by 86, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 86

Moving on to step 3:
If we divide 177 by 86, we get 2 and a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 5 after subtracting 172 from 177.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 86

Moving on to step 4:
When dividing 55 by 86, we get 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 86

Let's proceed to step 5:
If we divide 557 by 86, we get 6 and a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 206.0
Subtract 516 from 557 to get 41.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 86

Going ahead to step 6:
86 goes into 411 4 times with a remainder of 67.
Write down 4 as next digit of the result. 
Result so far: 2064.0
The remainder is 67 after subtracting 344 from 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
If we divide 670 by 86, we get 7 and a remainder of 68.
The next digit of our result is 7. 
Result so far: 2064.7
Subtracting 602 from 670 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
If we divide 680 by 86, we get 7 and a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 2064.77
Subtract 602 from 680 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 2064.77 with a remaining 0.078.
