670866 ÷ 4 
The aim is to understand the frequency of 4 in 670866.

Advancing to step 1:
If we divide 6 by 4, we get 1 and 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.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 4

Advancing to step 2:
When dividing 27 by 4, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 24 from 27 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 4

On to step 3:
If we divide 30 by 4, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
Deduct 28 from 30 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 4

Moving on to step 4:
4 goes into 28 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 1677.0
If we take 28 away from 28, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 4

On to step 5:
The number 4 fits into 6 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 16771.0
The remainder is 2 after subtracting 4 from 6.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 4

Advancing to step 6:
If we divide 26 by 4, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 167716.0
The remainder is 2 after subtracting 24 from 26.
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 7:
20 divided by 4 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 167716.5
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.

Going ahead to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 167716.5
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.

On to step 9:
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: 167716.5
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 outcome is 167716.5, with a leftover of 0.0.
