921878 divided by 4 
We want to figure out the number of times 921878 can be divided by 4.

On to step 1:
9 divided by 4 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 1 after subtracting 8 from 9.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

Going ahead to step 2:
If we divide 12 by 4, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 12 from 12 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 4

On to step 3:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 230.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 4

Let's proceed to step 4:
The number 4 fits into 18 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 2304.0
The remainder is 2 after subtracting 16 from 18.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 4

Let's proceed to step 5:
27 divided by 4 is 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 23046.0
If we take 24 away from 27, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 4

Going ahead to step 6:
38 divided by 4 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 230469.0
Deduct 36 from 38 and we're left 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.

On to step 7:
20 divided by 4 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 230469.5
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 230469.5
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.

On to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 230469.5
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.

The final result is 230469.5 with a remainder of 0.0.
