We look at the division of 254557 by 15 
We want to figure out the number of times 254557 can be divided by 15.

Let's proceed to step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 15

Step 2:
When dividing 25 by 15, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 15 from 25 to get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 15

Step 3:
The number 15 fits into 104 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 90 from 104 and we're left with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 15

Let's proceed to step 4:
The number 15 fits into 145 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 169.0
If we subtract 135 from 145, we get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 15

On to step 5:
15 goes into 105 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 1697.0
If we take 105 away from 105, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 15

Going ahead to step 6:
15 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 16970.0
The remainder is 7 after subtracting 0 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
15 can be fit into 70 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 16970.4
If we subtract 60 from 70, 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.

Step 8:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 16970.46
The remainder is 10 after subtracting 90 from 100.
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:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 16970.466
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.

Our division results in 16970.466 with a remaining 0.001.
