We're dividing 168999 by 86 
We want to figure out the number of times 168999 can be divided by 86.

Advancing to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 86

Advancing to step 2:
86 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 86

On to step 3:
If we divide 168 by 86, we get 1 and a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 82 after subtracting 86 from 168.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 86

Advancing to step 4:
When dividing 829 by 86, we get 9 with a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 774 from 829, we get 55.
Take the next digit (9) from the dividend and append it to 55, then repeat: 559 / 86

Advancing to step 5:
The number 86 fits into 559 6 times, leaving a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
Deduct 516 from 559 and we're left with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 86

Step 6:
When dividing 439 by 86, we get 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 1965.0
If we subtract 430 from 439, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 86 fits into 90 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1965.1
The remainder is 4 after subtracting 86 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1965.1
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.

Moving on to step 9:
86 goes into 400 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 1965.104
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.

Advancing to step 10:
560 divided by 86 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 1965.1046
Subtracting 516 from 560 leaves us 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.

Step 11:
86 goes into 440 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 1965.10465
Subtracting 430 from 440 leaves us 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.

Step 12:
When dividing 100 by 86, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1965.104651
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.

Step 13:
If we divide 140 by 86, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 1965.1046511
If we subtract 86 from 140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 1965.1046511 with a remaining 5.4e-07.
