Advancing to step 1:
7 divided by 15 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 15

Going ahead to step 2:
The number 15 fits into 70 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 60 from 70 to get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 15

Moving on to step 3:
102 divided by 15 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtracting 90 from 102 leaves us with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 15

Step 4:

Let's proceed to step 5:
15 goes into 58 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 4683.0
The remainder is 13 after subtracting 45 from 58.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 15

Moving on to step 6:
15 goes into 135 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result.

0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 46839.0
Subtracting 0 from 0 leaves us with 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 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 46839.0
Subtracting 0 from 0 leaves us with 0.
