596912 divided by 4 
The aim is to understand the frequency of 4 in 596912.

Step 1:
The number 4 fits into 5 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 4 from 5 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 4

Going ahead to step 2:
If we divide 19 by 4, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 3 after subtracting 16 from 19.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 4

Going ahead to step 3:
If we divide 36 by 4, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 149.0
If we take 36 away from 36, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 4

Moving on to step 4:
The number 4 fits into 9 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1492.0
Deduct 8 from 9 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 4

Let's proceed to step 5:
The number 4 fits into 11 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 14922.0
Subtracting 8 from 11 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 4

Step 6:
32 divided by 4 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 149228.0
Subtract 32 from 32 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.

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: 149228.0
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.

Step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 149228.0
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 final result is 149228.0 with a remainder of 0.0.
