112407 divided by 15 
Our goal is to divide 112407 by 15.

Going ahead to step 1:
15 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 15

Advancing to step 2:
11 divided by 15 is 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 15

Step 3:
15 can be fit into 112 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 105 from 112, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 15

Let's proceed to step 4:
When dividing 74 by 15, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we subtract 60 from 74, we get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 15

On to step 5:
When dividing 140 by 15, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 749.0
Subtract 135 from 140 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 15

Going ahead to step 6:
When dividing 57 by 15, we get 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 7493.0
Subtract 45 from 57 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 15 fits into 120 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 7493.8
Subtract 120 from 120 to 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.
Write down 0 as next digit of the result. 
Result so far: 7493.8
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.

Step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 7493.8
The remainder is 0 after subtracting 0 from 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 7493.8, with a leftover of 0.0.
