We look at the division of 651294 by 84 
The aim is to understand the frequency of 84 in 651294.

Let's proceed to step 1:
When dividing 6 by 84, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 84

Going ahead to step 2:
The number 84 fits into 65 0 times, leaving a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 84

Step 3:
84 goes into 651 7 times with a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 588 from 651, we get 63.
Take the next digit (2) from the dividend and append it to 63, then repeat: 632 / 84

Moving on to step 4:
If we divide 632 by 84, we get 7 and a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Subtracting 588 from 632 leaves us with 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 84

Let's proceed to step 5:
If we divide 449 by 84, we get 5 and a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 775.0
If we subtract 420 from 449, we get 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 84

Moving on to step 6:
The number 84 fits into 294 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 7753.0
Subtract 252 from 294 to 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.

Advancing to step 7:
84 can be fit into 420 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 7753.5
The remainder is 0 after subtracting 420 from 420.
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 8:
84 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7753.5
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.

Advancing to step 9:
0 divided by 84 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7753.5
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 quotient of the division is 7753.5, and the remainder is 0.0.
