Let's divide 917942 by 4
Let's see how many times 4 fits into 917942.

Step 1:
The number 4 fits into 9 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 8 from 9, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 4

Step 2:
The number 4 fits into 11 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 3 after subtracting 8 from 11.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 4

Moving on to step 3:
4 goes into 37 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
If we subtract 36 from 37, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 4

Moving on to step 4:
The number 4 fits into 19 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 2294.0
If we subtract 16 from 19, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 4

Going ahead to step 5:
If we divide 34 by 4, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 22948.0
Subtract 32 from 34 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 4

On to step 6:
4 goes into 22 5 times with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 229485.0
Subtract 20 from 22 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 229485.5
Deduct 20 from 20 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.

Moving on to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 229485.5
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.

Going ahead to step 9:
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: 229485.5
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 229485.5 with a remaining 0.0.
