We look at the division of 97758719 by 84 
The aim is to understand the frequency of 84 in 97758719.

Advancing to step 1:
84 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 84

Step 2:
84 goes into 97 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 13 after subtracting 84 from 97.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 84

Step 3:
84 goes into 137 1 times with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 84 from 137 leaves us with 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 84

Advancing to step 4:
84 can be fit into 535 6 times, resulting in a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Subtract 504 from 535 to get 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 84

Advancing to step 5:
The number 84 fits into 318 3 times, leaving a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 1163.0
The remainder is 66 after subtracting 252 from 318.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 84

Let's proceed to step 6:
84 can be fit into 667 7 times, resulting in a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 11637.0
The remainder is 79 after subtracting 588 from 667.
Fetch the next digit (1) from the dividend, attach it to 79 and continue: 791 / 84

Step 7:
791 divided by 84 is 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 116379.0
Deduct 756 from 791 and we're left with 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 84

Going ahead to step 8:
359 divided by 84 is 4 with a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 1163794.0
Subtract 336 from 359 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
84 can be fit into 230 2 times, resulting in a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 1163794.2
Subtracting 168 from 230 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
84 goes into 620 7 times with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 1163794.27
The remainder is 32 after subtracting 588 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
84 can be fit into 320 3 times, resulting in a remainder of 68.
The next digit of our result is 3. 
Result so far: 1163794.273
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.

On to step 12:
If we divide 680 by 84, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1163794.2738
Subtracting 672 from 680 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.

Advancing to step 13:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 1163794.2738
Subtracting 0 from 80 leaves us 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.

Going ahead to step 14:
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: 1163794.273809
Subtracting 756 from 800 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 15:
The number 84 fits into 440 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1163794.2738095
Deduct 420 from 440 and we're left 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.

Advancing to step 16:
If we divide 200 by 84, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1163794.27380952
Subtract 168 from 200 to 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.

After the division, we end up with 1163794.27380952 and a remainder of 3.2e-08.
