Let's divide 86459412 by 171
Our goal is to divide 86459412 by 171.

Advancing to step 1:
When dividing 8 by 171, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 171

Step 2:
171 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 171

Going ahead to step 3:
171 goes into 864 5 times with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 855 away from 864, we end up with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 171

Going ahead to step 4:
The number 171 fits into 95 0 times, leaving a remainder of 95.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtracting 0 from 95 leaves us with 95.
Fetch the next digit (9) from the dividend, attach it to 95 and continue: 959 / 171

Let's proceed to step 5:
959 divided by 171 is 5 with a remainder of 104.
Put 5 as the next digit of the answer. 
Result so far: 505.0
If we subtract 855 from 959, we get 104.
Fetch the next digit (4) from the dividend, attach it to 104 and continue: 1044 / 171

Going ahead to step 6:
The number 171 fits into 1044 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 5056.0
Deduct 1026 from 1044 and we're left with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 171

Going ahead to step 7:
When dividing 181 by 171, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 50561.0
The remainder is 10 after subtracting 171 from 181.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 171

On to step 8:
When dividing 102 by 171, we get 0 with a remainder of 102.
The next digit of our result is 0. 
Result so far: 505610.0
If we subtract 0 from 102, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 9:
When dividing 1020 by 171, we get 5 with a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 505610.5
If we take 855 away from 1020, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 10:
If we divide 1650 by 171, we get 9 and a remainder of 111.
Record the quotient 9 as the next digit in the result. 
Result so far: 505610.59
If we take 1539 away from 1650, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 11:
171 can be fit into 1110 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 505610.596
Deduct 1026 from 1110 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 12:
840 divided by 171 is 4 with a remainder of 156.
Use 4 as the next digit of our solution. 
Result so far: 505610.5964
If we subtract 684 from 840, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 13:
171 goes into 1560 9 times with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 505610.59649
Subtract 1539 from 1560 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
210 divided by 171 is 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 505610.596491
Subtracting 171 from 210 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 15:
171 goes into 390 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 505610.5964912
If we subtract 342 from 390, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
171 goes into 480 2 times with a remainder of 138.
The next digit of our result is 2. 
Result so far: 505610.59649122
Subtracting 342 from 480 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The quotient of the division is 505610.59649122, and the remainder is 1.38e-07.
