We divide 266134 by 4
The aim is to understand the frequency of 4 in 266134.

On to step 1:
4 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 4

Step 2:
If we divide 26 by 4, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 24 from 26 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 4

Moving on to step 3:
26 divided by 4 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we take 24 away from 26, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 4

Step 4:
4 goes into 21 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 665.0
If we subtract 20 from 21, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 4

Step 5:
When dividing 13 by 4, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 6653.0
Deduct 12 from 13 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 4

Advancing to step 6:
When dividing 14 by 4, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 66533.0
If we subtract 12 from 14, we get 2.
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:
4 goes into 20 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 66533.5
Subtract 20 from 20 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.

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: 66533.5
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.

Let's proceed to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 66533.5
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.

Our division results in 66533.5 with a remaining 0.0.
