We're dividing 977903 by 86 
We want to divide 977903 by 86.

On to step 1:
86 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 86

Going ahead to step 2:
If we divide 97 by 86, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 86 from 97 and we're left with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 86

Let's proceed to step 3:
117 divided by 86 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 86 away from 117, we end up with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 86

Moving on to step 4:
86 goes into 319 3 times with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we subtract 258 from 319, we get 61.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 86

Moving on to step 5:
86 can be fit into 610 7 times, resulting in a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 1137.0
Subtracting 602 from 610 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 86

On to step 6:
86 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 11370.0
Deduct 0 from 83 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 7:
86 goes into 830 9 times with a remainder of 56.
The next digit of our result is 9. 
Result so far: 11370.9
Subtract 774 from 830 to get 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 8:
When dividing 560 by 86, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 11370.96
Deduct 516 from 560 and we're left 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 9:
86 can be fit into 440 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 11370.965
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 86, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 11370.9651
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.

Going ahead to step 11:
When dividing 140 by 86, we get 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 11370.96511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 11370.96511 and a remainder of 5.4e-05.
