We look at the division of 78828678 by 980 
Let's see how many times 980 fits into 78828678.

Going ahead to step 1:
7 divided by 980 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 980

Let's proceed to step 2:
When dividing 78 by 980, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 980

Moving on to step 3:
980 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
If we take 0 away from 788, we end up with 788.
Take the next digit (2) from the dividend and append it to 788, then repeat: 7882 / 980

On to step 4:
When dividing 7882 by 980, we get 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 7840 from 7882, we get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 980

Going ahead to step 5:
428 divided by 980 is 0 with a remainder of 428.
The next digit of our result is 0. 
Result so far: 80.0
Subtract 0 from 428 to get 428.
Include the next digit (6) from the dividend after 428, then repeat: 4286 / 980

Advancing to step 6:
If we divide 4286 by 980, we get 4 and a remainder of 366.
Record the quotient 4 as the next digit in the result. 
Result so far: 804.0
Deduct 3920 from 4286 and we're left with 366.
Bring next digit (7) of the dividend behind the 366 and repeat the process: 3667 / 980

Advancing to step 7:
The number 980 fits into 3667 3 times, leaving a remainder of 727.
Use 3 as the next digit of our solution. 
Result so far: 8043.0
Subtracting 2940 from 3667 leaves us with 727.
Fetch the next digit (8) from the dividend, attach it to 727 and continue: 7278 / 980

Step 8:
When dividing 7278 by 980, we get 7 with a remainder of 418.
The next digit of our result is 7. 
Result so far: 80437.0
If we take 6860 away from 7278, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 9:
When dividing 4180 by 980, we get 4 with a remainder of 260.
Record the quotient 4 as the next digit in the result. 
Result so far: 80437.4
If we take 3920 away from 4180, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 10:
980 can be fit into 2600 2 times, resulting in a remainder of 640.
Use 2 as the next digit of our solution. 
Result so far: 80437.42
Subtract 1960 from 2600 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 11:
The number 980 fits into 6400 6 times, leaving a remainder of 520.
Put 6 as the next digit of the answer. 
Result so far: 80437.426
Subtract 5880 from 6400 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 12:
The number 980 fits into 5200 5 times, leaving a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 80437.4265
If we subtract 4900 from 5200, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 13:
980 can be fit into 3000 3 times, resulting in a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 80437.42653
If we take 2940 away from 3000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
600 divided by 980 is 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 80437.42653
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 15:
The number 980 fits into 6000 6 times, leaving a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 80437.4265306
Subtract 5880 from 6000 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
980 goes into 1200 1 times with a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 80437.42653061
If we subtract 980 from 1200, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final result is 80437.42653061 with a remainder of 2.2e-07.
