Let's divide 813063 by 4
The aim is to understand the frequency of 4 in 813063.

Step 1:
When dividing 8 by 4, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

Moving on to step 2:
If we divide 1 by 4, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 4

Let's proceed to step 3:
If we divide 13 by 4, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 203.0
The remainder is 1 after subtracting 12 from 13.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 4

Let's proceed to step 4:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2032.0
If we subtract 8 from 10, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 4

Advancing to step 5:
The number 4 fits into 26 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 20326.0
If we take 24 away from 26, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 4

Going ahead to step 6:
When dividing 23 by 4, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 203265.0
Deduct 20 from 23 and we're left 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 7:
The number 4 fits into 30 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 203265.7
The remainder is 2 after subtracting 28 from 30.
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.
Put 5 as the next digit of the answer. 
Result so far: 203265.75
The remainder is 0 after subtracting 20 from 20.
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:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 203265.75
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.

Step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 203265.75
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 203265.75, and the remainder is 0.0.
