We look at the division of 86479039 by 780 
Let's see how many times 780 fits into 86479039.

Going ahead to step 1:
When dividing 8 by 780, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 780

Advancing to step 2:
780 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (4) from the dividend, add it to 86, then carry on: 864 / 780

Going ahead to step 3:
780 can be fit into 864 1 times, resulting in a remainder of 84.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 780 from 864 leaves us with 84.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 780

Step 4:
When dividing 847 by 780, we get 1 with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 780 from 847 and we're left with 67.
Append the next digit (9) from the dividend to 67 and continue with: 679 / 780

On to step 5:
780 goes into 679 0 times with a remainder of 679.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Deduct 0 from 679 and we're left with 679.
Include the next digit (0) from the dividend after 679, then repeat: 6790 / 780

Step 6:
If we divide 6790 by 780, we get 8 and a remainder of 550.
The number 8 becomes the next digit in our result. 
Result so far: 1108.0
The remainder is 550 after subtracting 6240 from 6790.
Fetch the next digit (3) from the dividend, attach it to 550 and continue: 5503 / 780

Let's proceed to step 7:
If we divide 5503 by 780, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 11087.0
The remainder is 43 after subtracting 5460 from 5503.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 780

Step 8:
When dividing 439 by 780, we get 0 with a remainder of 439.
Write down 0 as next digit of the result. 
Result so far: 110870.0
Deduct 0 from 439 and we're left with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 9:
780 goes into 4390 5 times with a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 110870.5
Subtract 3900 from 4390 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 10:
780 can be fit into 4900 6 times, resulting in a remainder of 220.
Use 6 as the next digit of our solution. 
Result so far: 110870.56
Subtract 4680 from 4900 to 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.

Advancing to step 11:
If we divide 2200 by 780, we get 2 and a remainder of 640.
Put 2 as the next digit of the answer. 
Result so far: 110870.562
If we subtract 1560 from 2200, we 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 12:
If we divide 6400 by 780, we get 8 and a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 110870.5628
Subtracting 6240 from 6400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
780 goes into 1600 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 110870.56282
If we subtract 1560 from 1600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
When dividing 400 by 780, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 110870.56282
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 15:
If we divide 4000 by 780, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 110870.5628205
Subtracting 3900 from 4000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
780 can be fit into 1000 1 times, resulting in a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 110870.56282051
If we subtract 780 from 1000, 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.

In conclusion, the division gives 110870.56282051 with a balance of 2.2e-07.
