We're dividing 4869234 by 4 
The aim is to understand the frequency of 4 in 4869234.

On to step 1:
4 goes into 4 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 4 from 4, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Advancing to step 2:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 8 from 8 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 4

Going ahead to step 3:
If we divide 6 by 4, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Deduct 4 from 6 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 4

Let's proceed to step 4:
When dividing 29 by 4, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1217.0
The remainder is 1 after subtracting 28 from 29.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

On to step 5:
4 goes into 12 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 12173.0
If we subtract 12 from 12, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 4

Advancing to step 6:
3 divided by 4 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 121730.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 4

Advancing to step 7:
When dividing 34 by 4, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 1217308.0
If we take 32 away from 34, we end up 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.
Put 5 as the next digit of the answer. 
Result so far: 1217308.5
If we take 20 away from 20, 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 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1217308.5
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.

On to step 10:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1217308.5
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 outcome is 1217308.5, with a leftover of 0.0.
