657102 ÷ 84 
The aim is to understand the frequency of 84 in 657102.

Moving on to step 1:
If we divide 6 by 84, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 84

Advancing to step 2:
65 divided by 84 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 84

Step 3:
If we divide 657 by 84, we get 7 and a remainder of 69.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 588 from 657, we get 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 84

Advancing to step 4:
When dividing 691 by 84, we get 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 78.0
The remainder is 19 after subtracting 672 from 691.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 84

Moving on to step 5:
84 goes into 190 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 782.0
Deduct 168 from 190 and we're left with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 84

Going ahead to step 6:
84 goes into 222 2 times with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 7822.0
Deduct 168 from 222 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
84 can be fit into 540 6 times, resulting in a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 7822.6
Deduct 504 from 540 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 7822.64
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
When dividing 240 by 84, we get 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 7822.642
Deduct 168 from 240 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
If we divide 720 by 84, we get 8 and a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 7822.6428
If we subtract 672 from 720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
When dividing 480 by 84, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 7822.64285
Subtracting 420 from 480 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
84 goes into 600 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 7822.642857
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
The number 84 fits into 120 1 times, leaving a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 7822.6428571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 7822.64285714
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 7822.64285714 with a remaining 2.4e-08.
