We look at the division of 43479 by 15 
We're looking to find how many times 15 goes into 43479.

Step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 15

On to step 2:
If we divide 43 by 15, we get 2 and a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 30 from 43 to get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 15

Step 3:
134 divided by 15 is 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 120 away from 134, we end up with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 15

Step 4:
15 goes into 147 9 times with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 289.0
The remainder is 12 after subtracting 135 from 147.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 15

Moving on to step 5:
If we divide 129 by 15, we get 8 and a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 2898.0
If we take 120 away from 129, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 6:
90 divided by 15 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 2898.6
If we subtract 90 from 90, 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.

On to step 7:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2898.6
If we take 0 away from 0, we end up 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.

On to 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: 2898.6
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.

Our division results in 2898.6 with a remaining 0.0.
