Let's divide 922451 by 4
The aim is to understand the frequency of 4 in 922451.

Let's proceed to step 1:
The number 4 fits into 9 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 8 from 9, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 4

Going ahead to step 2:
The number 4 fits into 12 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 12 from 12 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 4

Step 3:
If we divide 2 by 4, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 230.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 4

Moving on to step 4:
When dividing 24 by 4, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 2306.0
The remainder is 0 after subtracting 24 from 24.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 4

Advancing to step 5:
4 can be fit into 5 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 23061.0
Subtracting 4 from 5 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 4

Let's proceed to step 6:
When dividing 11 by 4, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 230612.0
If we subtract 8 from 11, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 230612.7
Subtracting 28 from 30 leaves us 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.

Moving on to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 230612.75
If we take 20 away from 20, 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.

Moving on to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 230612.75
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 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 230612.75
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.

Our division results in 230612.75 with a remaining 0.0.
