8707289 divided by 778 
We want to figure out the number of times 8707289 can be divided by 778.

Let's proceed to step 1:
8 divided by 778 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 778

Step 2:
The number 778 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 778

Step 3:
When dividing 870 by 778, we get 1 with a remainder of 92.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 92 after subtracting 778 from 870.
Grab the next digit (7) from the dividend, add it to 92, then carry on: 927 / 778

Advancing to step 4:
927 divided by 778 is 1 with a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 778 from 927, we get 149.
Take the next digit (2) from the dividend and append it to 149, then repeat: 1492 / 778

Moving on to step 5:
If we divide 1492 by 778, we get 1 and a remainder of 714.
Write down 1 as next digit of the result. 
Result so far: 111.0
The remainder is 714 after subtracting 778 from 1492.
Grab the next digit (8) from the dividend, add it to 714, then carry on: 7148 / 778

Let's proceed to step 6:
7148 divided by 778 is 9 with a remainder of 146.
The next digit of our result is 9. 
Result so far: 1119.0
If we subtract 7002 from 7148, we get 146.
Append the next digit (9) from the dividend to 146 and continue with: 1469 / 778

Let's proceed to step 7:
If we divide 1469 by 778, we get 1 and a remainder of 691.
Use 1 as the next digit of our solution. 
Result so far: 11191.0
Subtracting 778 from 1469 leaves us with 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Step 8:
6910 divided by 778 is 8 with a remainder of 686.
Write down 8 as next digit of the result. 
Result so far: 11191.8
Deduct 6224 from 6910 and we're left with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Moving on to step 9:
The number 778 fits into 6860 8 times, leaving a remainder of 636.
Use 8 as the next digit of our solution. 
Result so far: 11191.88
The remainder is 636 after subtracting 6224 from 6860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The final outcome is 11191.88, with a leftover of 0.636.
