We divide 86885178 by 780
We want to divide 86885178 by 780.

Moving on to step 1:
The number 780 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 780

Moving on to step 2:
The number 780 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 780

On to step 3:
When dividing 868 by 780, we get 1 with a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 780 from 868 and we're left with 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 780

Step 4:
If we divide 888 by 780, we get 1 and a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 780 away from 888, we end up with 108.
Include the next digit (5) from the dividend after 108, then repeat: 1085 / 780

Step 5:
The number 780 fits into 1085 1 times, leaving a remainder of 305.
Put 1 as the next digit of the answer. 
Result so far: 111.0
If we take 780 away from 1085, we end up with 305.
Grab the next digit (1) from the dividend, add it to 305, then carry on: 3051 / 780

Advancing to step 6:
If we divide 3051 by 780, we get 3 and a remainder of 711.
Write down 3 as next digit of the result. 
Result so far: 1113.0
If we take 2340 away from 3051, we end up with 711.
Take the next digit (7) from the dividend and append it to 711, then repeat: 7117 / 780

On to step 7:
780 goes into 7117 9 times with a remainder of 97.
The next digit of our result is 9. 
Result so far: 11139.0
If we take 7020 away from 7117, we end up with 97.
Take the next digit (8) from the dividend and append it to 97, then repeat: 978 / 780

Step 8:
780 can be fit into 978 1 times, resulting in a remainder of 198.
Put 1 as the next digit of the answer. 
Result so far: 111391.0
The remainder is 198 after subtracting 780 from 978.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 9:
780 goes into 1980 2 times with a remainder of 420.
The number 2 becomes the next digit in our result. 
Result so far: 111391.2
If we take 1560 away from 1980, 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.

Going ahead to step 10:
4200 divided by 780 is 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 111391.25
Subtracting 3900 from 4200 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
780 can be fit into 3000 3 times, resulting in a remainder of 660.
The number 3 becomes the next digit in our result. 
Result so far: 111391.253
If we take 2340 away from 3000, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 12:
780 can be fit into 6600 8 times, resulting in a remainder of 360.
The next digit of our result is 8. 
Result so far: 111391.2538
If we subtract 6240 from 6600, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 13:
If we divide 3600 by 780, we get 4 and a remainder of 480.
The next digit of our result is 4. 
Result so far: 111391.25384
Subtracting 3120 from 3600 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 14:
4800 divided by 780 is 6 with a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 111391.253846
If we take 4680 away from 4800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
1200 divided by 780 is 1 with a remainder of 420.
Write down 1 as next digit of the result. 
Result so far: 111391.2538461
Subtracting 780 from 1200 leaves us 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.

Moving on to step 16:
If we divide 4200 by 780, we get 5 and a remainder of 300.
The next digit of our result is 5. 
Result so far: 111391.25384615
Subtracting 3900 from 4200 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 111391.25384615 with a remainder of 3e-07.
