We look at the division of 921071 by 25 
We want to figure out the number of times 921071 can be divided by 25.

Going ahead to step 1:
9 divided by 25 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 25

Going ahead to step 2:
If we divide 92 by 25, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 3.0
If we take 75 away from 92, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 25

Step 3:
When dividing 171 by 25, we get 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we take 150 away from 171, we end up with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 25

On to step 4:
25 goes into 210 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 368.0
If we take 200 away from 210, we end up with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 25

Advancing to step 5:
The number 25 fits into 107 4 times, leaving a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 3684.0
The remainder is 7 after subtracting 100 from 107.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 25

On to step 6:
25 goes into 71 2 times with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 36842.0
Subtracting 50 from 71 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
25 can be fit into 210 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 36842.8
If we take 200 away from 210, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 25 fits into 100 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 36842.84
If we subtract 100 from 100, 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.

Step 9:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36842.84
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.

Let's proceed to step 10:
25 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 36842.84
If we take 0 away from 0, 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.

Our division results in 36842.84 with a remaining 0.0.
