We divide 98121971 by 779
We're looking to find how many times 779 goes into 98121971.

On to step 1:
779 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 779

Step 2:
The number 779 fits into 98 0 times, leaving a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Include the next digit (1) from the dividend after 98, then repeat: 981 / 779

Step 3:
779 can be fit into 981 1 times, resulting in a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 779 from 981 leaves us with 202.
Grab the next digit (2) from the dividend, add it to 202, then carry on: 2022 / 779

Going ahead to step 4:
The number 779 fits into 2022 2 times, leaving a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1558 from 2022 leaves us with 464.
Include the next digit (1) from the dividend after 464, then repeat: 4641 / 779

Let's proceed to step 5:
779 can be fit into 4641 5 times, resulting in a remainder of 746.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Deduct 3895 from 4641 and we're left with 746.
Bring next digit (9) of the dividend behind the 746 and repeat the process: 7469 / 779

Moving on to step 6:
7469 divided by 779 is 9 with a remainder of 458.
Record the quotient 9 as the next digit in the result. 
Result so far: 1259.0
Deduct 7011 from 7469 and we're left with 458.
Include the next digit (7) from the dividend after 458, then repeat: 4587 / 779

On to step 7:
779 can be fit into 4587 5 times, resulting in a remainder of 692.
The next digit of our result is 5. 
Result so far: 12595.0
Subtracting 3895 from 4587 leaves us with 692.
Append the next digit (1) from the dividend to 692 and continue with: 6921 / 779

Advancing to step 8:
The number 779 fits into 6921 8 times, leaving a remainder of 689.
The next digit of our result is 8. 
Result so far: 125958.0
Subtracting 6232 from 6921 leaves us with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Advancing to step 9:
6890 divided by 779 is 8 with a remainder of 658.
Record the quotient 8 as the next digit in the result. 
Result so far: 125958.8
Deduct 6232 from 6890 and we're left with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Moving on to step 10:
If we divide 6580 by 779, we get 8 and a remainder of 348.
The number 8 becomes the next digit in our result. 
Result so far: 125958.88
Deduct 6232 from 6580 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Our division results in 125958.88 with a remaining 0.348.
