258739 divided by 4 
The aim is to understand the frequency of 4 in 258739.

Going ahead to step 1:
4 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 4

Advancing to step 2:
4 goes into 25 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 24 from 25, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 4

Step 3:
4 goes into 18 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 64.0
The remainder is 2 after subtracting 16 from 18.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 4

Step 4:
4 can be fit into 27 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 646.0
If we take 24 away from 27, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

Advancing to step 5:
33 divided by 4 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 6468.0
The remainder is 1 after subtracting 32 from 33.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 4

Advancing to step 6:
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: 64684.0
Deduct 16 from 19 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
4 goes into 30 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 64684.7
If we take 28 away from 30, we end up 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.

Let's proceed to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 64684.75
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.

Going ahead to step 9:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 64684.75
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.

Advancing to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 64684.75
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.

The final result is 64684.75 with a remainder of 0.0.
