881673 ÷ 4 
The aim is to understand the frequency of 4 in 881673.

Advancing 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
Subtract 8 from 8 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 4

Step 2:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 4

Going ahead to step 3:
When dividing 1 by 4, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 220.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 4

Moving on to step 4:
16 divided by 4 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 2204.0
The remainder is 0 after subtracting 16 from 16.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 4

On to step 5:
When dividing 7 by 4, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 22041.0
The remainder is 3 after subtracting 4 from 7.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 4

Step 6:
4 goes into 33 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 220418.0
Deduct 32 from 33 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 220418.2
Subtract 8 from 10 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.

Advancing to step 8:
20 divided by 4 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 220418.25
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.

Let's proceed to step 9:
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: 220418.25
If we take 0 away from 0, we end up 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.

Going ahead to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 220418.25
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.

After the division, we end up with 220418.25 and a remainder of 0.0.
