603923 divided by 4 
We want to figure out the number of times 603923 can be divided by 4.

Let's proceed to step 1:
4 goes into 6 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 4 from 6.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 4

Going ahead to step 2:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 20 from 20 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

Let's proceed to step 3:
4 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 150.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 4

Step 4:
When dividing 39 by 4, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 1509.0
Subtracting 36 from 39 leaves us with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 4

Let's proceed to step 5:
When dividing 32 by 4, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 15098.0
Subtracting 32 from 32 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 4

Advancing to step 6:
If we divide 3 by 4, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 150980.0
Subtracting 0 from 3 leaves us 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.

Going ahead to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 150980.7
Subtract 28 from 30 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.

Moving on to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 150980.75
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.

On to step 9:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 150980.75
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.

Going ahead to step 10:
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: 150980.75
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.

After the division, we end up with 150980.75 and a remainder of 0.0.
