We're dividing 15012913 by 725 
We want to figure out the number of times 15012913 can be divided by 725.

On to step 1:
725 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 725

On to step 2:
If we divide 15 by 725, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 725

Moving on to step 3:
When dividing 150 by 725, we get 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 150, we get 150.
Include the next digit (1) from the dividend after 150, then repeat: 1501 / 725

Advancing to step 4:
The number 725 fits into 1501 2 times, leaving a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1450 from 1501, we get 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 725

Step 5:
725 goes into 512 0 times with a remainder of 512.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 512, we get 512.
Include the next digit (9) from the dividend after 512, then repeat: 5129 / 725

Moving on to step 6:
The number 725 fits into 5129 7 times, leaving a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 207.0
If we take 5075 away from 5129, we end up with 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 725

Going ahead to step 7:
If we divide 541 by 725, we get 0 and a remainder of 541.
The next digit of our result is 0. 
Result so far: 2070.0
Subtracting 0 from 541 leaves us with 541.
Grab the next digit (3) from the dividend, add it to 541, then carry on: 5413 / 725

Step 8:
5413 divided by 725 is 7 with a remainder of 338.
Write down 7 as next digit of the result. 
Result so far: 20707.0
If we subtract 5075 from 5413, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 9:
When dividing 3380 by 725, we get 4 with a remainder of 480.
Use 4 as the next digit of our solution. 
Result so far: 20707.4
If we take 2900 away from 3380, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 10:
725 goes into 4800 6 times with a remainder of 450.
The number 6 becomes the next digit in our result. 
Result so far: 20707.46
If we take 4350 away from 4800, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 11:
When dividing 4500 by 725, we get 6 with a remainder of 150.
Write down 6 as next digit of the result. 
Result so far: 20707.466
Deduct 4350 from 4500 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Our division results in 20707.466 with a remaining 0.015.
