We're dividing 836626 by 4 
The aim is to understand the frequency of 4 in 836626.

Step 1:
4 goes into 8 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 8 from 8 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 4

Step 2:
3 divided by 4 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 3, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 4

Step 3:
When dividing 36 by 4, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 209.0
Subtracting 36 from 36 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 4

Let's proceed to step 4:
If we divide 6 by 4, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 2091.0
Subtracting 4 from 6 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 4

Going ahead to step 5:
4 goes into 22 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 20915.0
Subtracting 20 from 22 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 4

Step 6:
When dividing 26 by 4, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 209156.0
Deduct 24 from 26 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.

Let's proceed to step 7:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 209156.5
Subtracting 20 from 20 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.

Step 8:
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: 209156.5
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.

Going ahead to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 209156.5
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 result is 209156.5 with a remainder of 0.0.
