300373 divided by 4 
The aim is to understand the frequency of 4 in 300373.

On to step 1:
3 divided by 4 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 4

Advancing to step 2:
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: 7.0
Subtracting 28 from 30 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 4

Moving on to step 3:
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: 75.0
Subtracting 20 from 20 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 4

Going ahead to step 4:
3 divided by 4 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 750.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 4

Step 5:
37 divided by 4 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 7509.0
The remainder is 1 after subtracting 36 from 37.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 4

Advancing to step 6:
When dividing 13 by 4, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 75093.0
The remainder is 1 after subtracting 12 from 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
4 can be fit into 10 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 75093.2
The remainder is 2 after subtracting 8 from 10.
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:
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: 75093.25
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.

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: 75093.25
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.

Let's proceed 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: 75093.25
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 quotient of the division is 75093.25, and the remainder is 0.0.
