664136 divided by 4 
The aim is to understand the frequency of 4 in 664136.

Advancing to step 1:
6 divided by 4 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 4 from 6 and we're left with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 4

On to step 2:
The number 4 fits into 26 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 2 after subtracting 24 from 26.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 4

Let's proceed to step 3:
24 divided by 4 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
Subtract 24 from 24 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 4

Step 4:
If we divide 1 by 4, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 1660.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 4

Advancing to step 5:
If we divide 13 by 4, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 16603.0
If we subtract 12 from 13, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 4

Moving on to step 6:
The number 4 fits into 16 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 166034.0
Subtract 16 from 16 to 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.

Moving on to step 7:
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: 166034.0
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.

Moving on to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 166034.0
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 outcome is 166034.0, with a leftover of 0.0.
