We look at the division of 44405603 by 4 
The aim is to understand the frequency of 4 in 44405603.

Let's proceed to step 1:
If we divide 4 by 4, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 4 away from 4, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 4

Moving on to step 2:
The number 4 fits into 4 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 11.0
If we take 4 away from 4, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 4

Going ahead to step 3:
4 divided by 4 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 111.0
Subtracting 4 from 4 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 4

On to step 4:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1110.0
If we take 0 away from 0, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 4

Let's proceed to step 5:
5 divided by 4 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 11101.0
Subtract 4 from 5 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 4

On to step 6:
16 divided by 4 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 111014.0
If we subtract 16 from 16, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 4

Step 7:
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: 1110140.0
If we take 0 away from 0, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 4

Let's proceed to step 8:
4 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 11101400.0
If we take 0 away from 3, 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.

Going ahead to step 9:
4 can be fit into 30 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 11101400.7
Deduct 28 from 30 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.

Going ahead to step 10:
When dividing 20 by 4, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11101400.75
If we subtract 20 from 20, 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.

Going ahead to step 11:
If we divide 0 by 4, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 11101400.75
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.

Going ahead to step 12:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11101400.75
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.

The final result is 11101400.75 with a remainder of 0.0.
