We look at the division of 588597 by 84 
The aim is to understand the frequency of 84 in 588597.

Moving on to step 1:
The number 84 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 84

On to step 2:
If we divide 58 by 84, we get 0 and a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 84

Going ahead to step 3:
When dividing 588 by 84, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 588 from 588, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 84

Moving on to step 4:
The number 84 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we take 0 away from 5, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 84

Moving on to step 5:
When dividing 59 by 84, we get 0 with a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 700.0
If we take 0 away from 59, we end up with 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 84

On to step 6:
When dividing 597 by 84, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 7007.0
The remainder is 9 after subtracting 588 from 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 84, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 7007.1
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
84 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 7007.1
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
If we divide 600 by 84, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 7007.107
Subtract 588 from 600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
The number 84 fits into 120 1 times, leaving a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 7007.1071
Deduct 84 from 120 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.

On to step 11:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 7007.10714
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.

Moving on to step 12:
The number 84 fits into 240 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 7007.107142
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 13:
When dividing 720 by 84, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 7007.1071428
Deduct 672 from 720 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 14:
84 goes into 480 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 7007.10714285
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 7007.10714285 with a remainder of 6e-08.
