89170 ÷ 86 
Our goal is to divide 89170 by 86.

Advancing to step 1:
86 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 86

Advancing to step 2:
If we divide 89 by 86, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 86 away from 89, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 86

Moving on to step 3:
When dividing 31 by 86, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 31, we end up with 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 86

Moving on to step 4:
86 can be fit into 317 3 times, resulting in a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Subtract 258 from 317 to get 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 86

Going ahead to step 5:
86 can be fit into 590 6 times, resulting in a remainder of 74.
The next digit of our result is 6. 
Result so far: 1036.0
The remainder is 74 after subtracting 516 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 6:
The number 86 fits into 740 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 1036.8
The remainder is 52 after subtracting 688 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
If we divide 520 by 86, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 1036.86
Subtracting 516 from 520 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 86 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1036.86
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
400 divided by 86 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 1036.8604
If we take 344 away from 400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
When dividing 560 by 86, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 1036.86046
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
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: 1036.860465
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
100 divided by 86 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1036.8604651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
When dividing 140 by 86, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 1036.86046511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 1036.86046511 with a remainder of 5.4e-08.
