We look at the division of 653948 by 84 
The aim is to understand the frequency of 84 in 653948.

Let's proceed to step 1:
If we divide 6 by 84, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 84

On to step 2:
If we divide 65 by 84, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 84

Advancing to step 3:
The number 84 fits into 653 7 times, leaving a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 588 from 653 to get 65.
Append the next digit (9) from the dividend to 65 and continue with: 659 / 84

Advancing to step 4:
659 divided by 84 is 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
The remainder is 71 after subtracting 588 from 659.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 84

Moving on to step 5:
84 goes into 714 8 times with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 778.0
The remainder is 42 after subtracting 672 from 714.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 84

Moving on to step 6:
If we divide 428 by 84, we get 5 and a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 7785.0
Subtracting 420 from 428 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
When dividing 80 by 84, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 7785.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
If we divide 800 by 84, we get 9 and a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 7785.09
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
84 goes into 440 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 7785.095
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 7785.0952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
320 divided by 84 is 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 7785.09523
Subtract 252 from 320 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 12:
When dividing 680 by 84, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 7785.095238
The remainder is 8 after subtracting 672 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
If we divide 80 by 84, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 7785.095238
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
When dividing 800 by 84, we get 9 with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 7785.09523809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 7785.09523809 with a remainder of 4.4e-08.
