We look at the division of 411681 by 4 
The aim is to understand the frequency of 4 in 411681.

Going ahead to step 1:
4 goes into 4 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 4 away from 4, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

Going ahead to step 2:
If we divide 1 by 4, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

Moving on to step 3:
4 goes into 11 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 102.0
If we take 8 away from 11, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 4

Going ahead to step 4:
4 can be fit into 36 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 1029.0
Subtract 36 from 36 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Moving on to step 5:
4 goes into 8 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 10292.0
Subtracting 8 from 8 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 4

Advancing to step 6:
If we divide 1 by 4, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 102920.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 4, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 102920.2
Deduct 8 from 10 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 4 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 102920.25
Deduct 20 from 20 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 9:
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: 102920.25
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.

Moving on to step 10:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 102920.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 102920.25 and a remainder of 0.0.
