We look at the division of 443017 by 4 
The aim is to understand the frequency of 4 in 443017.

On to step 1:
If we divide 4 by 4, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 4 from 4, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 4

Advancing to step 2:
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: 11.0
Subtract 4 from 4 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

Let's proceed to step 3:
4 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 110.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 4

On to step 4:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 1107.0
If we take 28 away from 30, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 4

Moving on to step 5:
21 divided by 4 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 11075.0
Deduct 20 from 21 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 4

On to step 6:
4 goes into 17 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 110754.0
Subtracting 16 from 17 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
4 goes into 10 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 110754.2
If we take 8 away from 10, 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.

On to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 110754.25
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.

Moving on to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 110754.25
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.

Let's proceed to step 10:
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: 110754.25
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 110754.25 with a remainder of 0.0.
