Let's divide 86113971 by 780
Let's see how many times 780 fits into 86113971.

Moving on to step 1:
8 divided by 780 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 780

Advancing to step 2:
780 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 780

Moving on to step 3:
780 goes into 861 1 times with a remainder of 81.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 780 from 861 leaves us with 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 780

Step 4:
If we divide 811 by 780, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 780 from 811 to get 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 780

Moving on to step 5:
When dividing 313 by 780, we get 0 with a remainder of 313.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
If we subtract 0 from 313, we get 313.
Bring next digit (9) of the dividend behind the 313 and repeat the process: 3139 / 780

Going ahead to step 6:
780 goes into 3139 4 times with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 1104.0
Deduct 3120 from 3139 and we're left with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 780

Going ahead to step 7:
780 goes into 197 0 times with a remainder of 197.
The next digit of our result is 0. 
Result so far: 11040.0
If we subtract 0 from 197, we get 197.
Fetch the next digit (1) from the dividend, attach it to 197 and continue: 1971 / 780

Let's proceed to step 8:
1971 divided by 780 is 2 with a remainder of 411.
Use 2 as the next digit of our solution. 
Result so far: 110402.0
Subtracting 1560 from 1971 leaves us with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Going ahead to step 9:
If we divide 4110 by 780, we get 5 and a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 110402.5
Subtract 3900 from 4110 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
780 goes into 2100 2 times with a remainder of 540.
Record the quotient 2 as the next digit in the result. 
Result so far: 110402.52
If we subtract 1560 from 2100, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 11:
780 can be fit into 5400 6 times, resulting in a remainder of 720.
Record the quotient 6 as the next digit in the result. 
Result so far: 110402.526
The remainder is 720 after subtracting 4680 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 12:
The number 780 fits into 7200 9 times, leaving a remainder of 180.
The number 9 becomes the next digit in our result. 
Result so far: 110402.5269
Subtracting 7020 from 7200 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 13:
780 can be fit into 1800 2 times, resulting in a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 110402.52692
Subtract 1560 from 1800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
780 goes into 2400 3 times with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 110402.526923
If we take 2340 away from 2400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
When dividing 600 by 780, we get 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 110402.526923
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 16:
6000 divided by 780 is 7 with a remainder of 540.
Write down 7 as next digit of the result. 
Result so far: 110402.52692307
If we subtract 5460 from 6000, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The quotient of the division is 110402.52692307, and the remainder is 5.4e-07.
