Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 980

Moving on to step 2:
The number 980 fits into 76 0 times, leaving a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Take the next digit (7) from the dividend and append it to 76, then repeat: 767 / 980

On to step 3:
If we divide 767 by 980, we get 0 and a remainder of 767.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 767 and we're left with 767.
Fetch the next digit (8) from the dividend, attach it to 767 and continue: 7678 / 980

Advancing to step 4:
When dividing 7678 by 980, we get 7 with a remainder of 818.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 6860 from 7678 to get 818.
Grab the next digit (0) from the dividend, add it to 818, then carry on: 8180 / 980

Step 5:
If we divide 8180 by 980, we get 8 and a remainder of 340.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 7840 from 8180 and we're left with 340.
Grab the next digit (6) from the dividend, add it to 340, then carry on: 3406 / 980

Going ahead to step 6:
980 goes into 3406 3 times with a remainder of 466.
Put 3 as the next digit of the answer. 
Result so far: 783.0
If we take 2940 away from 3406, we end up with 466.
Bring next digit (5) of the dividend behind the 466 and repeat the process: 4665 / 980

Step 7:
980 goes into 4665 4 times with a remainder of 745.
The next digit of our result is 4. 
Result so far: 7834.0
The remainder is 745 after subtracting 3920 from 4665.
Bring next digit (7) of the dividend behind the 745 and repeat the process: 7457 / 980

On to step 8:
7457 divided by 980 is 7 with a remainder of 597.
Record the quotient 7 as the next digit in the result. 
Result so far: 78347.0
If we take 6860 away from 7457, we end up with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Going ahead to step 9:
When dividing 5970 by 980, we get 6 with a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 78347.6
If we subtract 5880 from 5970, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
If we divide 900 by 980, we get 0 and a remainder of 900.
Write down 0 as next digit of the result. 
Result so far: 78347.6
If we take 0 away from 900, we end up with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Step 11:
980 can be fit into 9000 9 times, resulting in a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 78347.609
Subtract 8820 from 9000 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
980 goes into 1800 1 times with a remainder of 820.
Put 1 as the next digit of the answer. 
Result so far: 78347.6091
The remainder is 820 after subtracting 980 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 13:
980 can be fit into 8200 8 times, resulting in a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 78347.60918
The remainder is 360 after subtracting 7840 from 8200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 14:
980 goes into 3600 3 times with a remainder of 660.
Write down 3 as next digit of the result. 
Result so far: 78347.609183
Deduct 2940 from 3600 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 15:
If we divide 6600 by 980, we get 6 and a remainder of 720.
Write down 6 as next digit of the result. 
Result so far: 78347.6091836
Deduct 5880 from 6600 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 16:
The number 980 fits into 7200 7 times, leaving a remainder of 340.
Use 7 as the next digit of our solution. 
Result so far: 78347.60918367
If we subtract 6860 from 7200, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final result is 78347.60918367 with a remainder of 3.4e-07.
