972909 divided by 84 
The aim is to understand the frequency of 84 in 972909.

On to step 1:
84 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 84

Step 2:
The number 84 fits into 97 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 84 from 97 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 84

Moving on to step 3:
84 goes into 132 1 times with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 48 after subtracting 84 from 132.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 84

Step 4:
84 can be fit into 489 5 times, resulting in a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 115.0
If we subtract 420 from 489, we get 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 84

Let's proceed to step 5:
84 goes into 690 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 1158.0
Subtracting 672 from 690 leaves us with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 84

Step 6:
If we divide 189 by 84, we get 2 and a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 11582.0
Subtract 168 from 189 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
If we divide 210 by 84, we get 2 and a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 11582.2
If we subtract 168 from 210, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
When dividing 420 by 84, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11582.25
Subtracting 420 from 420 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.

Moving on to step 9:
84 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11582.25
Subtracting 0 from 0 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.

Moving on to step 10:
84 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11582.25
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 quotient of the division is 11582.25, and the remainder is 0.0.
