We divide 196420 by 4
The aim is to understand the frequency of 4 in 196420.

Going ahead to step 1:
When dividing 1 by 4, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 4

Step 2:
19 divided by 4 is 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 16 away from 19, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 4

Advancing to step 3:
4 can be fit into 36 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 49.0
Deduct 36 from 36 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 4

Advancing to step 4:
4 can be fit into 4 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 491.0
If we take 4 away from 4, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 4

Moving on to step 5:
When dividing 2 by 4, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 4910.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 4

Moving on to step 6:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 49105.0
If we take 20 away from 20, 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.

Advancing to step 7:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 49105.0
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.

Moving on to step 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 49105.0
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.

Our division results in 49105.0 with a remaining 0.0.
