We divide 748936 by 15
We want to figure out the number of times 748936 can be divided by 15.

Going ahead to step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 15

On to step 2:
When dividing 74 by 15, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 14 after subtracting 60 from 74.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 15

Advancing to step 3:
15 can be fit into 148 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 135 from 148, we get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 15

On to step 4:
15 goes into 139 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 499.0
If we subtract 135 from 139, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 15

Step 5:
15 goes into 43 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 4992.0
Deduct 30 from 43 and we're left with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 15

Step 6:
If we divide 136 by 15, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 49929.0
The remainder is 1 after subtracting 135 from 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 15 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 49929.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
15 goes into 100 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 49929.06
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
15 goes into 100 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 49929.066
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 49929.066, with a leftover of 0.001.
