We look at the division of 851313 by 25 
We want to figure out the number of times 851313 can be divided by 25.

Moving on to step 1:
25 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 25

On to step 2:
The number 25 fits into 85 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 75 from 85, we get 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 25

Step 3:
25 goes into 101 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we subtract 100 from 101, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 25

Moving on to step 4:
If we divide 13 by 25, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 340.0
Subtract 0 from 13 to get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 25

Let's proceed to step 5:
25 goes into 131 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 3405.0
Deduct 125 from 131 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 25

Let's proceed to step 6:
25 goes into 63 2 times with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 34052.0
Subtract 50 from 63 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
The number 25 fits into 130 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 34052.5
Subtracting 125 from 130 leaves us 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.

Going ahead to step 8:
When dividing 50 by 25, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 34052.52
If we subtract 50 from 50, 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.

Going ahead to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 34052.52
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.

Moving on to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 34052.52
The remainder is 0 after subtracting 0 from 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 34052.52 with a remaining 0.0.
