Let's divide 912171 by 4
We're looking to find how many times 4 goes into 912171.

On to step 1:
The number 4 fits into 9 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 8 away from 9, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 4

Step 2:
4 can be fit into 11 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 8 from 11 and we're left with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 4

Moving on to step 3:
4 goes into 32 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 228.0
The remainder is 0 after subtracting 32 from 32.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 4

On to step 4:
4 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 2280.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 4

Going ahead to step 5:
The number 4 fits into 17 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 22804.0
Subtract 16 from 17 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 4

Advancing to step 6:
11 divided by 4 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 228042.0
Deduct 8 from 11 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
The number 4 fits into 30 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 228042.7
Subtracting 28 from 30 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
4 goes into 20 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 228042.75
If we subtract 20 from 20, 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:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 228042.75
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.

Let's proceed to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 228042.75
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 228042.75 with a remaining 0.0.
