We look at the division of 98199391 by 780 
Our goal is to divide 98199391 by 780.

On to step 1:
780 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 780

Moving on to step 2:
When dividing 98 by 780, we get 0 with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Grab the next digit (1) from the dividend, add it to 98, then carry on: 981 / 780

Moving on to step 3:
780 goes into 981 1 times with a remainder of 201.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 780 from 981 leaves us with 201.
Take the next digit (9) from the dividend and append it to 201, then repeat: 2019 / 780

Going ahead to step 4:
If we divide 2019 by 780, we get 2 and a remainder of 459.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1560 from 2019 and we're left with 459.
Append the next digit (9) from the dividend to 459 and continue with: 4599 / 780

Moving on to step 5:
4599 divided by 780 is 5 with a remainder of 699.
Write down 5 as next digit of the result. 
Result so far: 125.0
If we take 3900 away from 4599, we end up with 699.
Append the next digit (3) from the dividend to 699 and continue with: 6993 / 780

On to step 6:
780 can be fit into 6993 8 times, resulting in a remainder of 753.
Use 8 as the next digit of our solution. 
Result so far: 1258.0
Deduct 6240 from 6993 and we're left with 753.
Include the next digit (9) from the dividend after 753, then repeat: 7539 / 780

Step 7:
The number 780 fits into 7539 9 times, leaving a remainder of 519.
The next digit of our result is 9. 
Result so far: 12589.0
Subtracting 7020 from 7539 leaves us with 519.
Fetch the next digit (1) from the dividend, attach it to 519 and continue: 5191 / 780

Advancing to step 8:
When dividing 5191 by 780, we get 6 with a remainder of 511.
Put 6 as the next digit of the answer. 
Result so far: 125896.0
If we subtract 4680 from 5191, we get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Step 9:
If we divide 5110 by 780, we get 6 and a remainder of 430.
Record the quotient 6 as the next digit in the result. 
Result so far: 125896.6
Deduct 4680 from 5110 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 10:
The number 780 fits into 4300 5 times, leaving a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 125896.65
The remainder is 400 after subtracting 3900 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 11:
The number 780 fits into 4000 5 times, leaving a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 125896.655
If we subtract 3900 from 4000, 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.

In conclusion, the division gives 125896.655 with a balance of 0.01.
