Let's divide 7485994 by 15
We want to figure out the number of times 7485994 can be divided by 15.

On to step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 15

Step 2:
15 goes into 74 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 60 from 74, we get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 15

Going ahead to step 3:
15 goes into 148 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we take 135 away from 148, we end up with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 15

Let's proceed to step 4:
15 goes into 135 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 499.0
The remainder is 0 after subtracting 135 from 135.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 15

Step 5:
The number 15 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 4990.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 15

Advancing to step 6:
When dividing 99 by 15, we get 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 49906.0
Subtracting 90 from 99 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 15

Step 7:
If we divide 94 by 15, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 499066.0
Deduct 90 from 94 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 15 fits into 40 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 499066.2
If we subtract 30 from 40, we 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.

On to step 9:
100 divided by 15 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 499066.26
Subtracting 90 from 100 leaves us 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.

Let's proceed to step 10:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 499066.266
If we subtract 90 from 100, we 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 result is 499066.266 with a remainder of 0.001.
