We're dividing 73850 by 4 
The aim is to understand the frequency of 4 in 73850.

On to step 1:
If we divide 7 by 4, we get 1 and 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.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 4

Advancing to step 2:
When dividing 33 by 4, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 1 after subtracting 32 from 33.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 4

Advancing to step 3:
When dividing 18 by 4, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 184.0
If we take 16 away from 18, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 4

Advancing to step 4:
If we divide 25 by 4, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 1846.0
If we subtract 24 from 25, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 4

Going ahead to step 5:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 18462.0
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 6:
20 divided by 4 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 18462.5
If we subtract 20 from 20, 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 7:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18462.5
Subtracting 0 from 0 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.

Let's proceed 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: 18462.5
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.

The final outcome is 18462.5, with a leftover of 0.0.
