Let's divide 79889679 by 780
Our goal is to divide 79889679 by 780.

Let's proceed to step 1:
7 divided by 780 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 780

Going ahead to step 2:
780 goes into 79 0 times with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 780

Step 3:
If we divide 798 by 780, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 18 after subtracting 780 from 798.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 780

On to step 4:
188 divided by 780 is 0 with a remainder of 188.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 188 and we're left with 188.
Fetch the next digit (9) from the dividend, attach it to 188 and continue: 1889 / 780

Moving on to step 5:
The number 780 fits into 1889 2 times, leaving a remainder of 329.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 1560 from 1889 leaves us with 329.
Fetch the next digit (6) from the dividend, attach it to 329 and continue: 3296 / 780

Step 6:
The number 780 fits into 3296 4 times, leaving a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 1024.0
The remainder is 176 after subtracting 3120 from 3296.
Fetch the next digit (7) from the dividend, attach it to 176 and continue: 1767 / 780

On to step 7:
780 goes into 1767 2 times with a remainder of 207.
Record the quotient 2 as the next digit in the result. 
Result so far: 10242.0
If we subtract 1560 from 1767, we get 207.
Include the next digit (9) from the dividend after 207, then repeat: 2079 / 780

On to step 8:
If we divide 2079 by 780, we get 2 and a remainder of 519.
Write down 2 as next digit of the result. 
Result so far: 102422.0
Subtract 1560 from 2079 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Advancing to step 9:
When dividing 5190 by 780, we get 6 with a remainder of 510.
Put 6 as the next digit of the answer. 
Result so far: 102422.6
If we take 4680 away from 5190, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Moving on to step 10:
If we divide 5100 by 780, we get 6 and a remainder of 420.
Write down 6 as next digit of the result. 
Result so far: 102422.66
If we take 4680 away from 5100, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final result is 102422.66 with a remainder of 0.42.
