We're dividing 7880456 by 977 
Our goal is to divide 7880456 by 977.

On to step 1:
7 divided by 977 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 977

Step 2:
977 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (8) from the dividend to 78 and continue with: 788 / 977

Advancing to step 3:
977 goes into 788 0 times with a remainder of 788.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 788 after subtracting 0 from 788.
Append the next digit (0) from the dividend to 788 and continue with: 7880 / 977

Let's proceed to step 4:
The number 977 fits into 7880 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 7816 from 7880 and we're left with 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 977

Advancing to step 5:
The number 977 fits into 644 0 times, leaving a remainder of 644.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
The remainder is 644 after subtracting 0 from 644.
Bring next digit (5) of the dividend behind the 644 and repeat the process: 6445 / 977

Let's proceed to step 6:
When dividing 6445 by 977, we get 6 with a remainder of 583.
Use 6 as the next digit of our solution. 
Result so far: 806.0
If we subtract 5862 from 6445, we get 583.
Append the next digit (6) from the dividend to 583 and continue with: 5836 / 977

Step 7:
977 can be fit into 5836 5 times, resulting in a remainder of 951.
Record the quotient 5 as the next digit in the result. 
Result so far: 8065.0
The remainder is 951 after subtracting 4885 from 5836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9510, and continue the process.

On to step 8:
977 goes into 9510 9 times with a remainder of 717.
Write down 9 as next digit of the result. 
Result so far: 8065.9
Subtract 8793 from 9510 to get 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Let's proceed to step 9:
977 goes into 7170 7 times with a remainder of 331.
Record the quotient 7 as the next digit in the result. 
Result so far: 8065.97
If we take 6839 away from 7170, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 10:
When dividing 3310 by 977, we get 3 with a remainder of 379.
Record the quotient 3 as the next digit in the result. 
Result so far: 8065.973
Subtract 2931 from 3310 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Going ahead to step 11:
If we divide 3790 by 977, we get 3 and a remainder of 859.
Use 3 as the next digit of our solution. 
Result so far: 8065.9733
Deduct 2931 from 3790 and we're left with 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Our division results in 8065.9733 with a remaining 0.00859.
