Let's divide 124791 by 15
We want to divide 124791 by 15.

On to step 1:
The number 15 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 15

Step 2:
If we divide 12 by 15, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 15

Let's proceed to step 3:
The number 15 fits into 124 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 120 from 124 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 15

Let's proceed to step 4:
15 can be fit into 47 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtracting 45 from 47 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 15

Moving on to step 5:
When dividing 29 by 15, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 831.0
Deduct 15 from 29 and we're left with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 15

Step 6:
15 can be fit into 141 9 times, resulting in a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 8319.0
Subtract 135 from 141 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 15 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 8319.4
If we subtract 60 from 60, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 15 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8319.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8319.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 8319.4, with a leftover of 0.0.
