21422136 divided by 4 
The aim is to understand the frequency of 4 in 21422136.

Let's proceed to step 1:
If we divide 2 by 4, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 4

Let's proceed to step 2:
21 divided by 4 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 20 from 21, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 4

Step 3:
If we divide 14 by 4, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 53.0
Subtract 12 from 14 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 4

Going ahead to step 4:
4 can be fit into 22 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 535.0
If we subtract 20 from 22, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 4

Going ahead to step 5:
4 can be fit into 22 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 5355.0
If we subtract 20 from 22, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 4

Step 6:
When dividing 21 by 4, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 53555.0
Subtracting 20 from 21 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 4

Step 7:
4 can be fit into 13 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 535553.0
The remainder is 1 after subtracting 12 from 13.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 4

On to step 8:
4 goes into 16 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 5355534.0
The remainder is 0 after subtracting 16 from 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5355534.0
If we take 0 away from 0, 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.

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: 5355534.0
Subtract 0 from 0 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.

The final outcome is 5355534.0, with a leftover of 0.0.
