We're dividing 86724 by 51 
Let's see how many times 51 fits into 86724.

Advancing to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 51

Going ahead to step 2:
86 divided by 51 is 1 with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 35 after subtracting 51 from 86.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 51

Step 3:
51 can be fit into 357 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 357 from 357, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 51

Step 4:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 170.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 51

Going ahead to step 5:
51 goes into 24 0 times with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 1700.0
The remainder is 24 after subtracting 0 from 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 6:
51 can be fit into 240 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 1700.4
Subtracting 204 from 240 leaves us 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.

Let's proceed to step 7:
The number 51 fits into 360 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 1700.47
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
51 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 1700.47
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
300 divided by 51 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 1700.4705
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
450 divided by 51 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 1700.47058
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
When dividing 420 by 51, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1700.470588
The remainder is 12 after subtracting 408 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 1700.470588 with a remaining 1.2e-06.
