Let's divide 66988807 by 980
We want to divide 66988807 by 980.

On to step 1:
When dividing 6 by 980, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 980

Moving on to step 2:
980 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 980

On to step 3:
The number 980 fits into 669 0 times, leaving a remainder of 669.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 669 leaves us with 669.
Include the next digit (8) from the dividend after 669, then repeat: 6698 / 980

Going ahead to step 4:
The number 980 fits into 6698 6 times, leaving a remainder of 818.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 5880 from 6698, we get 818.
Include the next digit (8) from the dividend after 818, then repeat: 8188 / 980

Let's proceed to step 5:
When dividing 8188 by 980, we get 8 with a remainder of 348.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtract 7840 from 8188 to get 348.
Grab the next digit (8) from the dividend, add it to 348, then carry on: 3488 / 980

Going ahead to step 6:
If we divide 3488 by 980, we get 3 and a remainder of 548.
Use 3 as the next digit of our solution. 
Result so far: 683.0
Subtract 2940 from 3488 to get 548.
Bring next digit (0) of the dividend behind the 548 and repeat the process: 5480 / 980

Advancing to step 7:
980 can be fit into 5480 5 times, resulting in a remainder of 580.
The number 5 becomes the next digit in our result. 
Result so far: 6835.0
If we take 4900 away from 5480, we end up with 580.
Take the next digit (7) from the dividend and append it to 580, then repeat: 5807 / 980

Moving on to step 8:
980 goes into 5807 5 times with a remainder of 907.
The number 5 becomes the next digit in our result. 
Result so far: 68355.0
The remainder is 907 after subtracting 4900 from 5807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9070, and continue the process.

Advancing to step 9:
If we divide 9070 by 980, we get 9 and a remainder of 250.
The next digit of our result is 9. 
Result so far: 68355.9
The remainder is 250 after subtracting 8820 from 9070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
The number 980 fits into 2500 2 times, leaving a remainder of 540.
Use 2 as the next digit of our solution. 
Result so far: 68355.92
The remainder is 540 after subtracting 1960 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 11:
5400 divided by 980 is 5 with a remainder of 500.
The next digit of our result is 5. 
Result so far: 68355.925
Deduct 4900 from 5400 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 12:
980 goes into 5000 5 times with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 68355.9255
If we subtract 4900 from 5000, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 68355.9255, with a leftover of 0.001.
