We're dividing 909951 by 25 
We're looking to find how many times 25 goes into 909951.

Moving on to step 1:
25 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 25

Let's proceed to step 2:
When dividing 90 by 25, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 75 from 90, we get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 25

On to step 3:
25 can be fit into 159 6 times, resulting in a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtracting 150 from 159 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 25

Advancing to step 4:
If we divide 99 by 25, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 363.0
Subtracting 75 from 99 leaves us with 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 25

Going ahead to step 5:
245 divided by 25 is 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 3639.0
Subtracting 225 from 245 leaves us with 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 25

Going ahead to step 6:
25 goes into 201 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 36398.0
Deduct 200 from 201 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 25, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 36398.0
The remainder is 10 after subtracting 0 from 10.
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 8:
100 divided by 25 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 36398.04
The remainder is 0 after subtracting 100 from 100.
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:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36398.04
Deduct 0 from 0 and we're left 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.

Step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 36398.04
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.

The final outcome is 36398.04, with a leftover of 0.0.
