We're dividing 513933 by 25 
We want to figure out the number of times 513933 can be divided by 25.

Going ahead to step 1:
5 divided by 25 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 25

Going ahead to step 2:
If we divide 51 by 25, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 50 away from 51, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 25

Advancing to step 3:
25 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 13 to get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 25

Going ahead to step 4:
25 goes into 139 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 205.0
The remainder is 14 after subtracting 125 from 139.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 25

Let's proceed to step 5:
143 divided by 25 is 5 with a remainder of 18.
The next digit of our result is 5. 
Result so far: 2055.0
If we take 125 away from 143, we end up with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 25

Advancing to step 6:
25 goes into 183 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 20557.0
The remainder is 8 after subtracting 175 from 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
25 can be fit into 80 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 20557.3
Deduct 75 from 80 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 25 fits into 50 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 20557.32
If we take 50 away from 50, 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.

Advancing to step 9:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20557.32
Subtract 0 from 0 to 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.

Moving on to step 10:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20557.32
Subtract 0 from 0 to 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.

After the division, we end up with 20557.32 and a remainder of 0.0.
