We divide 443943 by 4
The aim is to understand the frequency of 4 in 443943.

Let's proceed to step 1:
4 goes into 4 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 4

Advancing to step 2:
When dividing 4 by 4, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 4

Step 3:
When dividing 3 by 4, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 110.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 4

Advancing to step 4:
39 divided by 4 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1109.0
If we subtract 36 from 39, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 4

Advancing to step 5:
4 can be fit into 34 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 11098.0
If we take 32 away from 34, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 4

Let's proceed to step 6:
The number 4 fits into 23 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 110985.0
If we take 20 away from 23, we end up 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.

Step 7:
When dividing 30 by 4, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 110985.7
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.

Going ahead 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: 110985.75
Subtract 20 from 20 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.

Step 9:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 110985.75
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.

Step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 110985.75
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.

The quotient of the division is 110985.75, and the remainder is 0.0.
