598087 ÷ 84 
The aim is to understand the frequency of 84 in 598087.

Going ahead to step 1:
When dividing 5 by 84, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 84

Going ahead to step 2:
84 goes into 59 0 times with a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 84

Moving on to step 3:
When dividing 598 by 84, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 588 from 598 to get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 84

On to step 4:
The number 84 fits into 100 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we subtract 84 from 100, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 84

On to step 5:
If we divide 168 by 84, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 712.0
Subtract 168 from 168 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 84

Step 6:
The number 84 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 7120.0
Subtract 0 from 7 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 84, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 7120.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
When dividing 700 by 84, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 7120.08
Subtracting 672 from 700 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
280 divided by 84 is 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 7120.083
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
280 divided by 84 is 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 7120.0833
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 7120.0833 with a balance of 0.00028.
