We're dividing 626446 by 4 
The aim is to understand the frequency of 4 in 626446.

Step 1:
When dividing 6 by 4, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 4 from 6.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 4

On to step 2:
22 divided by 4 is 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 20 from 22, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 4

Let's proceed to step 3:
4 can be fit into 26 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
If we subtract 24 from 26, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 4

On to step 4:
4 can be fit into 24 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1566.0
Deduct 24 from 24 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 4

Going ahead to step 5:
4 goes into 4 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 15661.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 4

Moving on to step 6:
If we divide 6 by 4, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 156611.0
The remainder is 2 after subtracting 4 from 6.
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 7:
If we divide 20 by 4, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 156611.5
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.

Let's proceed to step 8:
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: 156611.5
If we subtract 0 from 0, 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.

On to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 156611.5
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 quotient of the division is 156611.5, and the remainder is 0.0.
