We look at the division of 171617 by 86 
Our goal is to divide 171617 by 86.

Advancing to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 86

Let's proceed to step 2:
17 divided by 86 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 86

On to step 3:
When dividing 171 by 86, we get 1 with a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 86 from 171, we get 85.
Bring next digit (6) of the dividend behind the 85 and repeat the process: 856 / 86

On to step 4:
86 goes into 856 9 times with a remainder of 82.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 82 after subtracting 774 from 856.
Bring next digit (1) of the dividend behind the 82 and repeat the process: 821 / 86

On to step 5:
86 can be fit into 821 9 times, resulting in a remainder of 47.
The next digit of our result is 9. 
Result so far: 199.0
If we subtract 774 from 821, we get 47.
Fetch the next digit (7) from the dividend, attach it to 47 and continue: 477 / 86

Advancing to step 6:
If we divide 477 by 86, we get 5 and a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 1995.0
If we take 430 away from 477, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
When dividing 470 by 86, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 1995.5
Subtracting 430 from 470 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
400 divided by 86 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 1995.54
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
560 divided by 86 is 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 1995.546
Subtract 516 from 560 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 10:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1995.5465
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
86 goes into 100 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1995.54651
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
When dividing 140 by 86, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 1995.546511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 1995.546511, and the remainder is 5.4e-06.
