878808 ÷ 4 
The aim is to understand the frequency of 4 in 878808.

Step 1:
4 goes into 8 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 4

Moving on to step 2:
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: 21.0
The remainder is 3 after subtracting 4 from 7.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 4

On to step 3:
4 can be fit into 38 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 219.0
Deduct 36 from 38 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 4

On to step 4:
If we divide 28 by 4, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 2197.0
Subtract 28 from 28 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 4

Step 5:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21970.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 4

Advancing to step 6:
8 divided by 4 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 219702.0
If we take 8 away from 8, 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.

Step 7:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 219702.0
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.

Step 8:
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: 219702.0
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.

The final result is 219702.0 with a remainder of 0.0.
