Let's divide 566190 by 4
The aim is to understand the frequency of 4 in 566190.

Moving on to step 1:
4 goes into 5 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 4 from 5 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 4

Going ahead to step 2:
If we divide 16 by 4, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 0 after subtracting 16 from 16.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 4

Step 3:
4 can be fit into 6 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Subtracting 4 from 6 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 4

On to step 4:
4 can be fit into 21 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 1415.0
If we subtract 20 from 21, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 4

Going ahead to step 5:
4 goes into 19 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 14154.0
Deduct 16 from 19 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 4

Advancing to step 6:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 141547.0
Subtract 28 from 30 to 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.

On to step 7:
4 goes into 20 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 141547.5
The remainder is 0 after subtracting 20 from 20.
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 8:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 141547.5
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.

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: 141547.5
Deduct 0 from 0 and we're left 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 141547.5, with a leftover of 0.0.
