Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 977

On to step 2:
If we divide 77 by 977, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 977

Advancing to step 3:
The number 977 fits into 771 0 times, leaving a remainder of 771.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 771 and we're left with 771.
Grab the next digit (0) from the dividend, add it to 771, then carry on: 7710 / 977

Advancing to step 4:
977 goes into 7710 7 times with a remainder of 871.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 6839 from 7710, we get 871.
Append the next digit (7) from the dividend to 871 and continue with: 8717 / 977

On to step 5:
977 can be fit into 8717 8 times, resulting in a remainder of 901.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 7816 from 8717 to get 901.
Fetch the next digit (1) from the dividend, attach it to 901 and continue: 9011 / 977

Moving on to step 6:
977 goes into 9011 9 times with a remainder of 218.
Use 9 as the next digit of our solution. 
Result so far: 789.0
The remainder is 218 after subtracting 8793 from 9011.
Take the next digit (5) from the dividend and append it to 218, then repeat: 2185 / 977

Let's proceed to step 7:
When dividing 2185 by 977, we get 2 with a remainder of 231.
Write down 2 as next digit of the result. 
Result so far: 7892.0
If we subtract 1954 from 2185, we get 231.
Append the next digit (9) from the dividend to 231 and continue with: 2319 / 977

Going ahead to step 8:
The number 977 fits into 2319 2 times, leaving a remainder of 365.
The next digit of our result is 2. 
Result so far: 78922.0
Subtract 1954 from 2319 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 9:
When dividing 3650 by 977, we get 3 with a remainder of 719.
Record the quotient 3 as the next digit in the result. 
Result so far: 78922.3
If we subtract 2931 from 3650, we get 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Advancing to step 10:
977 goes into 7190 7 times with a remainder of 351.
Record the quotient 7 as the next digit in the result. 
Result so far: 78922.37
The remainder is 351 after subtracting 6839 from 7190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 11:
If we divide 3510 by 977, we get 3 and a remainder of 579.
The next digit of our result is 3. 
Result so far: 78922.373
The remainder is 579 after subtracting 2931 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 12:
5790 divided by 977 is 5 with a remainder of 905.
The next digit of our result is 5. 
Result so far: 78922.3735
Deduct 4885 from 5790 and we're left with 905.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9050, and continue the process.

Going ahead to step 13:
If we divide 9050 by 977, we get 9 and a remainder of 257.
The next digit of our result is 9. 
Result so far: 78922.37359
Subtract 8793 from 9050 to get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 14:
If we divide 2570 by 977, we get 2 and a remainder of 616.
Use 2 as the next digit of our solution. 
Result so far: 78922.373592
The remainder is 616 after subtracting 1954 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 15:
If we divide 6160 by 977, we get 6 and a remainder of 298.
Write down 6 as next digit of the result. 
Result so far: 78922.3735926
If we take 5862 away from 6160, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 16:
2980 divided by 977 is 3 with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 78922.37359263
Subtract 2931 from 2980 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 78922.37359263 with a remainder of 4.9e-08.
