We divide 868719 by 4
The aim is to understand the frequency of 4 in 868719.

Let's proceed to step 1:
4 goes into 8 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 8 away from 8, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 4

Going ahead to step 2:
6 divided by 4 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 4 from 6 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 4

Moving on to step 3:
The number 4 fits into 28 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 217.0
If we take 28 away from 28, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 4

On to step 4:
The number 4 fits into 7 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 2171.0
If we take 4 away from 7, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 4

On to step 5:
When dividing 31 by 4, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 21717.0
If we take 28 away from 31, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 4

Going ahead to step 6:
4 can be fit into 39 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 217179.0
The remainder is 3 after subtracting 36 from 39.
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:
30 divided by 4 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 217179.7
Deduct 28 from 30 and we're left 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 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 217179.75
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.

Going ahead to step 9:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 217179.75
Subtracting 0 from 0 leaves us 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.

Moving on to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 217179.75
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 217179.75 with a remainder of 0.0.
