Let's divide 722437 by 84
The aim is to understand the frequency of 84 in 722437.

Advancing to step 1:
84 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 84

Going ahead to step 2:
The number 84 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 84

On to step 3:
84 can be fit into 722 8 times, resulting in a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 50 after subtracting 672 from 722.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 84

Let's proceed to step 4:
If we divide 504 by 84, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 86.0
Deduct 504 from 504 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 84

Moving on to step 5:
84 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 860.0
If we subtract 0 from 3, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 84

Let's proceed to step 6:
If we divide 37 by 84, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 8600.0
Subtracting 0 from 37 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
If we divide 370 by 84, we get 4 and a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 8600.4
Subtract 336 from 370 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
If we divide 340 by 84, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 8600.44
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 8600.44 and a remainder of 0.004.
