We look at the division of 972780 by 86 
We're looking to find how many times 86 goes into 972780.

On to step 1:
If we divide 9 by 86, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 86

On to step 2:
When dividing 97 by 86, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 86 away from 97, we end up with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 86

Advancing to step 3:
86 can be fit into 112 1 times, resulting in a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 86 from 112 to get 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 86

Moving on to step 4:
The number 86 fits into 267 3 times, leaving a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 113.0
The remainder is 9 after subtracting 258 from 267.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 86

Going ahead to step 5:
98 divided by 86 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1131.0
If we subtract 86 from 98, we get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 86

Let's proceed to step 6:
When dividing 120 by 86, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 11311.0
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
When dividing 340 by 86, we get 3 with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 11311.3
Subtracting 258 from 340 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 8:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 11311.39
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
86 goes into 460 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11311.395
If we take 430 away from 460, we end up 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.

Advancing to step 10:
When dividing 300 by 86, we get 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 11311.3953
If we take 258 away from 300, we end up 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.

Step 11:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 11311.39534
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
The number 86 fits into 760 8 times, leaving a remainder of 72.
The next digit of our result is 8. 
Result so far: 11311.395348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
86 goes into 720 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 11311.3953488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 11311.3953488 and a remainder of 3.2e-07.
