8 divided by 977 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 977

Going ahead to step 2:
If we divide 85 by 977, we get 0 and a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 977

On to step 3:
When dividing 851 by 977, we get 0 with a remainder of 851.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 851 leaves us with 851.
Grab the next digit (0) from the dividend, add it to 851, then carry on: 8510 / 977

Moving on to step 4:
If we divide 8510 by 977, we get 8 and a remainder of 694.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7816 from 8510 leaves us with 694.
Take the next digit (6) from the dividend and append it to 694, then repeat: 6946 / 977

On to step 5:
977 can be fit into 6946 7 times, resulting in a remainder of 107.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Subtract 6839 from 6946 to get 107.
Fetch the next digit (3) from the dividend, attach it to 107 and continue: 1073 / 977

Going ahead to step 6:
The number 977 fits into 1073 1 times, leaving a remainder of 96.
Record the quotient 1 as the next digit in the result. 
Result so far: 871.0
If we subtract 977 from 1073, we get 96.
Fetch the next digit (2) from the dividend, attach it to 96 and continue: 962 / 977

On to step 7:
962 divided by 977 is 0 with a remainder of 962.
The number 0 becomes the next digit in our result. 
Result so far: 8710.0
Subtracting 0 from 962 leaves us with 962.
Take the next digit (1) from the dividend and append it to 962, then repeat: 9621 / 977

Let's proceed to step 8:
9621 divided by 977 is 9 with a remainder of 828.
Put 9 as the next digit of the answer. 
Result so far: 87109.0
Subtract 8793 from 9621 to get 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Going ahead to step 9:
When dividing 8280 by 977, we get 8 with a remainder of 464.
Record the quotient 8 as the next digit in the result. 
Result so far: 87109.8
Subtracting 7816 from 8280 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 10:
977 can be fit into 4640 4 times, resulting in a remainder of 732.
Put 4 as the next digit of the answer. 
Result so far: 87109.84
Subtracting 3908 from 4640 leaves us with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Step 11:
977 goes into 7320 7 times with a remainder of 481.
The next digit of our result is 7. 
Result so far: 87109.847
Subtracting 6839 from 7320 leaves us with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Advancing to step 12:
4810 divided by 977 is 4 with a remainder of 902.
Put 4 as the next digit of the answer. 
Result so far: 87109.8474
Deduct 3908 from 4810 and we're left with 902.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9020, and continue the process.

Going ahead to step 13:
The number 977 fits into 9020 9 times, leaving a remainder of 227.
Write down 9 as next digit of the result. 
Result so far: 87109.84749
The remainder is 227 after subtracting 8793 from 9020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Let's proceed to step 14:
If we divide 2270 by 977, we get 2 and a remainder of 316.
The number 2 becomes the next digit in our result. 
Result so far: 87109.847492
If we take 1954 away from 2270, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 15:
The number 977 fits into 3160 3 times, leaving a remainder of 229.
Record the quotient 3 as the next digit in the result. 
Result so far: 87109.8474923
The remainder is 229 after subtracting 2931 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 16:
977 goes into 2290 2 times with a remainder of 336.
Write down 2 as next digit of the result. 
Result so far: 87109.84749232
Deduct 1954 from 2290 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Our division results in 87109.84749232 with a remaining 3.36e-07.
