170776 divided by 86 
Our goal is to divide 170776 by 86.

Advancing to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 86

Moving on to step 2:
17 divided by 86 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 86

Going ahead to step 3:
86 can be fit into 170 1 times, resulting in a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 86 away from 170, we end up with 84.
Fetch the next digit (7) from the dividend, attach it to 84 and continue: 847 / 86

Advancing to step 4:
847 divided by 86 is 9 with a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 774 from 847 to get 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 86

Moving on to step 5:
86 can be fit into 737 8 times, resulting in a remainder of 49.
The next digit of our result is 8. 
Result so far: 198.0
Subtract 688 from 737 to get 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 86

Moving on to step 6:
496 divided by 86 is 5 with a remainder of 66.
Use 5 as the next digit of our solution. 
Result so far: 1985.0
If we subtract 430 from 496, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
86 can be fit into 660 7 times, resulting in a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 1985.7
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
86 goes into 580 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 1985.76
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
86 goes into 640 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 1985.767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1985.7674
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
If we divide 360 by 86, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1985.76744
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 1985.76744 and a remainder of 1.6e-05.
