Let's divide 921387 by 4
We're looking to find how many times 4 goes into 921387.

Advancing to step 1:
9 divided by 4 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 8 from 9, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 4

On to step 2:
12 divided by 4 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 12 from 12 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 4

On to step 3:
When dividing 1 by 4, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 230.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 4

Going ahead to step 4:
13 divided by 4 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 2303.0
The remainder is 1 after subtracting 12 from 13.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 4

Going ahead to step 5:
4 can be fit into 18 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 23034.0
Subtract 16 from 18 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 4

Advancing to step 6:
4 goes into 27 6 times with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 230346.0
The remainder is 3 after subtracting 24 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 4 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 230346.7
If we take 28 away from 30, we end up 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.

Going ahead to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 230346.75
Subtracting 20 from 20 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.

On to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 230346.75
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.

Let's proceed to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 230346.75
Subtract 0 from 0 to 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 quotient of the division is 230346.75, and the remainder is 0.0.
