We look at the division of 75023108 by 4 
The aim is to understand the frequency of 4 in 75023108.

Moving on to step 1:
7 divided by 4 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 3 after subtracting 4 from 7.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 4

Advancing to step 2:
If we divide 35 by 4, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 32 away from 35, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 4

Advancing to step 3:
When dividing 30 by 4, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
If we take 28 away from 30, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 4

Going ahead to step 4:
The number 4 fits into 22 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 1875.0
Subtracting 20 from 22 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 4

Advancing to step 5:
When dividing 23 by 4, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 18755.0
Deduct 20 from 23 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 4

Step 6:
4 goes into 31 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 187557.0
Subtract 28 from 31 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 4

Moving on to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1875577.0
If we take 28 away from 30, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 4

Moving on to step 8:
If we divide 28 by 4, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 18755777.0
If we subtract 28 from 28, 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.

Advancing to step 9:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18755777.0
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.

Moving on to step 10:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18755777.0
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.

The quotient of the division is 18755777.0, and the remainder is 0.0.
