722953 ÷ 84 
The aim is to understand the frequency of 84 in 722953.

Let's proceed to step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 84

On to step 2:
84 can be fit into 72 0 times, resulting in a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 84

Moving on to step 3:
When dividing 722 by 84, we get 8 with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 672 away from 722, we end up with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 84

Step 4:
509 divided by 84 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 86.0
If we take 504 away from 509, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 84

Advancing to step 5:
84 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 860.0
If we take 0 away from 55, we end up with 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 84

Advancing to step 6:
When dividing 553 by 84, we get 6 with a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 8606.0
If we take 504 away from 553, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
490 divided by 84 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 8606.5
Subtract 420 from 490 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
When dividing 700 by 84, we get 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 8606.58
Subtract 672 from 700 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
280 divided by 84 is 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 8606.583
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
When dividing 280 by 84, we get 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 8606.5833
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 8606.5833 with a remainder of 0.00028.
