We're dividing 86551704 by 780 
We're looking to find how many times 780 goes into 86551704.

Going ahead to step 1:
780 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 780

Let's proceed to step 2:
When dividing 86 by 780, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 780

Advancing to step 3:
780 can be fit into 865 1 times, resulting in a remainder of 85.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 780 from 865 and we're left with 85.
Append the next digit (5) from the dividend to 85 and continue with: 855 / 780

Step 4:
If we divide 855 by 780, we get 1 and a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 75 after subtracting 780 from 855.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 780

On to step 5:
780 can be fit into 751 0 times, resulting in a remainder of 751.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we subtract 0 from 751, we get 751.
Bring next digit (7) of the dividend behind the 751 and repeat the process: 7517 / 780

Advancing to step 6:
7517 divided by 780 is 9 with a remainder of 497.
The next digit of our result is 9. 
Result so far: 1109.0
Deduct 7020 from 7517 and we're left with 497.
Take the next digit (0) from the dividend and append it to 497, then repeat: 4970 / 780

Moving on to step 7:
The number 780 fits into 4970 6 times, leaving a remainder of 290.
Record the quotient 6 as the next digit in the result. 
Result so far: 11096.0
Subtract 4680 from 4970 to get 290.
Bring next digit (4) of the dividend behind the 290 and repeat the process: 2904 / 780

Step 8:
The number 780 fits into 2904 3 times, leaving a remainder of 564.
The number 3 becomes the next digit in our result. 
Result so far: 110963.0
Subtract 2340 from 2904 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 9:
780 can be fit into 5640 7 times, resulting in a remainder of 180.
The next digit of our result is 7. 
Result so far: 110963.7
If we take 5460 away from 5640, we end up 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.

On to step 10:
When dividing 1800 by 780, we get 2 with a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 110963.72
Deduct 1560 from 1800 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
2400 divided by 780 is 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 110963.723
Deduct 2340 from 2400 and we're left 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.

On to step 12:
600 divided by 780 is 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 110963.723
Subtract 0 from 600 to get 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 13:
780 goes into 6000 7 times with a remainder of 540.
Use 7 as the next digit of our solution. 
Result so far: 110963.72307
Deduct 5460 from 6000 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 14:
5400 divided by 780 is 6 with a remainder of 720.
The next digit of our result is 6. 
Result so far: 110963.723076
Subtract 4680 from 5400 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 15:
780 goes into 7200 9 times with a remainder of 180.
Record the quotient 9 as the next digit in the result. 
Result so far: 110963.7230769
Deduct 7020 from 7200 and we're left 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 16:
1800 divided by 780 is 2 with a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 110963.72307692
The remainder is 240 after subtracting 1560 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 110963.72307692 with a remaining 2.4e-07.
