We look at the division of 9915093 by 789 
Let's see how many times 789 fits into 9915093.

On to step 1:
The number 789 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 789

Step 2:
When dividing 99 by 789, we get 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 789

Going ahead to step 3:
When dividing 991 by 789, we get 1 with a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 789 from 991 to get 202.
Bring next digit (5) of the dividend behind the 202 and repeat the process: 2025 / 789

Step 4:
789 can be fit into 2025 2 times, resulting in a remainder of 447.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1578 from 2025 leaves us with 447.
Take the next digit (0) from the dividend and append it to 447, then repeat: 4470 / 789

Advancing to step 5:
789 can be fit into 4470 5 times, resulting in a remainder of 525.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Deduct 3945 from 4470 and we're left with 525.
Grab the next digit (9) from the dividend, add it to 525, then carry on: 5259 / 789

Going ahead to step 6:
The number 789 fits into 5259 6 times, leaving a remainder of 525.
The next digit of our result is 6. 
Result so far: 1256.0
If we subtract 4734 from 5259, we get 525.
Append the next digit (3) from the dividend to 525 and continue with: 5253 / 789

Let's proceed to step 7:
If we divide 5253 by 789, we get 6 and a remainder of 519.
Record the quotient 6 as the next digit in the result. 
Result so far: 12566.0
The remainder is 519 after subtracting 4734 from 5253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Step 8:
789 goes into 5190 6 times with a remainder of 456.
The next digit of our result is 6. 
Result so far: 12566.6
Subtract 4734 from 5190 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 9:
789 goes into 4560 5 times with a remainder of 615.
The number 5 becomes the next digit in our result. 
Result so far: 12566.65
Subtract 3945 from 4560 to get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

On to step 10:
The number 789 fits into 6150 7 times, leaving a remainder of 627.
The number 7 becomes the next digit in our result. 
Result so far: 12566.657
Subtract 5523 from 6150 to get 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

On to step 11:
The number 789 fits into 6270 7 times, leaving a remainder of 747.
The number 7 becomes the next digit in our result. 
Result so far: 12566.6577
Subtract 5523 from 6270 to get 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

After the division, we end up with 12566.6577 and a remainder of 0.00747.
