We divide 75820254 by 4
The aim is to understand the frequency of 4 in 75820254.

On to step 1:
If we divide 7 by 4, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 4 from 7 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 4

Let's proceed to step 2:
The number 4 fits into 35 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 32 from 35 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 4

Let's proceed to step 3:
When dividing 38 by 4, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 189.0
Subtract 36 from 38 to get 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: 1895.0
The remainder is 2 after subtracting 20 from 22.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

Going ahead to step 5:
When dividing 20 by 4, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 18955.0
Subtract 20 from 20 to get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 4

Moving on to step 6:
2 divided by 4 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 189550.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 4

On to step 7:
The number 4 fits into 25 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 1895506.0
If we subtract 24 from 25, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 4

Step 8:
4 goes into 14 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 18955063.0
Deduct 12 from 14 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.

Going ahead to step 9:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 18955063.5
Subtracting 20 from 20 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.

Going ahead to step 10:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18955063.5
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.

On to step 11:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18955063.5
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 18955063.5 with a remaining 0.0.
