We're dividing 339634 by 4 
The aim is to understand the frequency of 4 in 339634.

On to step 1:
4 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

Step 2:
If we divide 33 by 4, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 32 away from 33, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 4

Step 3:
4 goes into 19 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
The remainder is 3 after subtracting 16 from 19.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 4

Step 4:
36 divided by 4 is 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 849.0
If we take 36 away from 36, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 4

On to step 5:
4 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 8490.0
If we subtract 0 from 3, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 4

Advancing to step 6:
When dividing 34 by 4, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 84908.0
Subtracting 32 from 34 leaves us 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.

Moving on to step 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 84908.5
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.

Step 8:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 84908.5
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.

Let's proceed to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 84908.5
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 84908.5, with a leftover of 0.0.
