We look at the division of 90647765 by 780 
Let's see how many times 780 fits into 90647765.

Going ahead to step 1:
780 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 780

On to step 2:
780 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (6) from the dividend and append it to 90, then repeat: 906 / 780

On to step 3:
The number 780 fits into 906 1 times, leaving a remainder of 126.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 126 after subtracting 780 from 906.
Include the next digit (4) from the dividend after 126, then repeat: 1264 / 780

Step 4:
1264 divided by 780 is 1 with a remainder of 484.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 484 after subtracting 780 from 1264.
Take the next digit (7) from the dividend and append it to 484, then repeat: 4847 / 780

Going ahead to step 5:
The number 780 fits into 4847 6 times, leaving a remainder of 167.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtract 4680 from 4847 to get 167.
Take the next digit (7) from the dividend and append it to 167, then repeat: 1677 / 780

On to step 6:
780 goes into 1677 2 times with a remainder of 117.
Put 2 as the next digit of the answer. 
Result so far: 1162.0
If we take 1560 away from 1677, we end up with 117.
Grab the next digit (6) from the dividend, add it to 117, then carry on: 1176 / 780

Step 7:
780 goes into 1176 1 times with a remainder of 396.
The number 1 becomes the next digit in our result. 
Result so far: 11621.0
If we subtract 780 from 1176, we get 396.
Take the next digit (5) from the dividend and append it to 396, then repeat: 3965 / 780

On to step 8:
When dividing 3965 by 780, we get 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 116215.0
If we subtract 3900 from 3965, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 9:
The number 780 fits into 650 0 times, leaving a remainder of 650.
Use 0 as the next digit of our solution. 
Result so far: 116215.0
The remainder is 650 after subtracting 0 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 10:
6500 divided by 780 is 8 with a remainder of 260.
Write down 8 as next digit of the result. 
Result so far: 116215.08
Subtract 6240 from 6500 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 11:
The number 780 fits into 2600 3 times, leaving a remainder of 260.
The number 3 becomes the next digit in our result. 
Result so far: 116215.083
If we subtract 2340 from 2600, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 12:
780 can be fit into 2600 3 times, resulting in a remainder of 260.
Write down 3 as next digit of the result. 
Result so far: 116215.0833
If we subtract 2340 from 2600, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 116215.0833, with a leftover of 0.0026.
