We look at the division of 15125 by 33 
We're looking to find how many times 33 goes into 15125.

Advancing to step 1:
33 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 33

On to step 2:
When dividing 15 by 33, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 33

Advancing to step 3:
151 divided by 33 is 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 19 after subtracting 132 from 151.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 33

On to step 4:
The number 33 fits into 192 5 times, leaving a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Deduct 165 from 192 and we're left with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 33

Going ahead to step 5:
If we divide 275 by 33, we get 8 and a remainder of 11.
The next digit of our result is 8. 
Result so far: 458.0
Deduct 264 from 275 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 6:
When dividing 110 by 33, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 458.3
The remainder is 11 after subtracting 99 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 33 fits into 110 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 458.33
If we take 99 away from 110, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 458.33 and a remainder of 0.011.
