80866710 ÷ 977 
Let's see how many times 977 fits into 80866710.

Going ahead to step 1:
The number 977 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 977

Going ahead to step 2:
977 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 977

Let's proceed to step 3:
If we divide 808 by 977, we get 0 and a remainder of 808.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 808, we end up with 808.
Include the next digit (6) from the dividend after 808, then repeat: 8086 / 977

Let's proceed to step 4:
977 can be fit into 8086 8 times, resulting in a remainder of 270.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 7816 from 8086, we get 270.
Fetch the next digit (6) from the dividend, attach it to 270 and continue: 2706 / 977

On to step 5:
2706 divided by 977 is 2 with a remainder of 752.
Write down 2 as next digit of the result. 
Result so far: 82.0
The remainder is 752 after subtracting 1954 from 2706.
Bring next digit (7) of the dividend behind the 752 and repeat the process: 7527 / 977

Let's proceed to step 6:
977 goes into 7527 7 times with a remainder of 688.
Use 7 as the next digit of our solution. 
Result so far: 827.0
If we subtract 6839 from 7527, we get 688.
Append the next digit (1) from the dividend to 688 and continue with: 6881 / 977

Let's proceed to step 7:
If we divide 6881 by 977, we get 7 and a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 8277.0
Subtract 6839 from 6881 to get 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 977

Advancing to step 8:
If we divide 420 by 977, we get 0 and a remainder of 420.
Write down 0 as next digit of the result. 
Result so far: 82770.0
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 9:
977 goes into 4200 4 times with a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 82770.4
Subtract 3908 from 4200 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 10:
The number 977 fits into 2920 2 times, leaving a remainder of 966.
Put 2 as the next digit of the answer. 
Result so far: 82770.42
The remainder is 966 after subtracting 1954 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9660, and continue the process.

Step 11:
977 goes into 9660 9 times with a remainder of 867.
Put 9 as the next digit of the answer. 
Result so far: 82770.429
The remainder is 867 after subtracting 8793 from 9660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8670, and continue the process.

Let's proceed to step 12:
When dividing 8670 by 977, we get 8 with a remainder of 854.
Put 8 as the next digit of the answer. 
Result so far: 82770.4298
If we subtract 7816 from 8670, we get 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Advancing to step 13:
977 can be fit into 8540 8 times, resulting in a remainder of 724.
Use 8 as the next digit of our solution. 
Result so far: 82770.42988
The remainder is 724 after subtracting 7816 from 8540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

The final result is 82770.42988 with a remainder of 0.000724.
