Let's divide 210248 by 4
The aim is to understand the frequency of 4 in 210248.

Going ahead to step 1:
2 divided by 4 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 4

Moving on to step 2:
21 divided by 4 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
If we take 20 away from 21, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 4

Step 3:
When dividing 10 by 4, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 8 away from 10, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 4

Going ahead to step 4:
When dividing 22 by 4, we get 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 525.0
Subtracting 20 from 22 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 4

Going ahead to step 5:
When dividing 24 by 4, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 5256.0
Subtracting 24 from 24 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 4

Moving on to step 6:
If we divide 8 by 4, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 52562.0
Deduct 8 from 8 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.

Going ahead to step 7:
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: 52562.0
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.

Step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52562.0
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.

Our division results in 52562.0 with a remaining 0.0.
