Let's divide 851007 by 25
Let's see how many times 25 fits into 851007.

Step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 25

Advancing to step 2:
If we divide 85 by 25, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 75 from 85 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 25

Advancing to step 3:
25 goes into 101 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtracting 100 from 101 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 25

Let's proceed to step 4:
The number 25 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 340.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 25

Advancing to step 5:
When dividing 100 by 25, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 3404.0
Deduct 100 from 100 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 25

Going ahead to step 6:
25 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 34040.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 25, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 34040.2
If we take 50 away from 70, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 34040.28
If we take 200 away from 200, 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.

On to step 9:
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: 34040.28
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.

On to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34040.28
Subtracting 0 from 0 leaves us 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.

Our division results in 34040.28 with a remaining 0.0.
