We're dividing 745686 by 15 
We want to figure out the number of times 745686 can be divided by 15.

Let's proceed to step 1:
15 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 15

Let's proceed to step 2:
The number 15 fits into 74 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 14 after subtracting 60 from 74.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 15

Going ahead to step 3:
The number 15 fits into 145 9 times, leaving a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we subtract 135 from 145, we get 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 15

Step 4:
106 divided by 15 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 497.0
If we subtract 105 from 106, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 15

Moving on to step 5:
15 can be fit into 18 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 4971.0
The remainder is 3 after subtracting 15 from 18.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 15

Advancing to step 6:
The number 15 fits into 36 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 49712.0
Subtracting 30 from 36 leaves us with 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:
15 can be fit into 60 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 49712.4
Subtract 60 from 60 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.

Advancing to step 8:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49712.4
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.

Step 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 49712.4
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 result is 49712.4 with a remainder of 0.0.
