We look at the division of 758910 by 77 
We want to figure out the number of times 758910 can be divided by 77.

On to step 1:
7 divided by 77 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 77

Going ahead to step 2:
77 goes into 75 0 times with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 77

Let's proceed to step 3:
77 goes into 758 9 times with a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 693 from 758 to get 65.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 77

Step 4:
659 divided by 77 is 8 with a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 98.0
The remainder is 43 after subtracting 616 from 659.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 77

On to step 5:
431 divided by 77 is 5 with a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 985.0
The remainder is 46 after subtracting 385 from 431.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 77

Advancing to step 6:
77 can be fit into 460 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 9855.0
If we take 385 away from 460, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
750 divided by 77 is 9 with a remainder of 57.
The next digit of our result is 9. 
Result so far: 9855.9
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 8:
77 can be fit into 570 7 times, resulting in a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 9855.97
Subtract 539 from 570 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 9:
The number 77 fits into 310 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 9855.974
The remainder is 2 after subtracting 308 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
The number 77 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 9855.974
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 77, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 9855.97402
Subtracting 154 from 200 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
77 goes into 460 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 9855.974025
Subtract 385 from 460 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 13:
The number 77 fits into 750 9 times, leaving a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 9855.9740259
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 14:
77 goes into 570 7 times with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 9855.97402597
Subtract 539 from 570 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 9855.97402597, with a leftover of 3.1e-08.
