647823 ÷ 4 
The aim is to understand the frequency of 4 in 647823.

Advancing to step 1:
4 can be fit into 6 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 4 from 6.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 4

Moving on to step 2:
If we divide 24 by 4, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 0 after subtracting 24 from 24.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 4

Going ahead to step 3:
If we divide 7 by 4, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 161.0
Deduct 4 from 7 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 4

Let's proceed to step 4:
The number 4 fits into 38 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 1619.0
If we take 36 away from 38, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 4

Let's proceed to step 5:
The number 4 fits into 22 5 times, leaving a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 16195.0
Subtract 20 from 22 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 4

Step 6:
23 divided by 4 is 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 161955.0
If we take 20 away from 23, we end up 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.

Advancing to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 161955.7
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 8:
4 goes into 20 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 161955.75
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.

Step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 161955.75
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.

Advancing to step 10:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 161955.75
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.

Our division results in 161955.75 with a remaining 0.0.
