We look at the division of 51182 by 84 
The aim is to understand the frequency of 84 in 51182.

Advancing to step 1:
5 divided by 84 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 84

Advancing to step 2:
51 divided by 84 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 84

Let's proceed to step 3:
511 divided by 84 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 504 from 511, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 84

On to step 4:
If we divide 78 by 84, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 60.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 84

Advancing to step 5:
The number 84 fits into 782 9 times, leaving a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 609.0
If we subtract 756 from 782, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 6:
260 divided by 84 is 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 609.3
Deduct 252 from 260 and we're left 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.

On to step 7:
84 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 609.3
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.

Advancing to step 8:
84 goes into 800 9 times with a remainder of 44.
The next digit of our result is 9. 
Result so far: 609.309
If we subtract 756 from 800, we 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.

Advancing to step 9:
The number 84 fits into 440 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 609.3095
If we take 420 away from 440, we end up 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 10:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 609.30952
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.

Step 11:
The number 84 fits into 320 3 times, leaving a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 609.309523
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.

Let's proceed to step 12:
84 can be fit into 680 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 609.3095238
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.

Moving on to step 13:
The number 84 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 609.3095238
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.

The final outcome is 609.3095238, with a leftover of 8e-08.
