We divide 734579 by 84
The aim is to understand the frequency of 84 in 734579.

Going ahead to step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 84

Moving on to step 2:
73 divided by 84 is 0 with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Append the next digit (4) from the dividend to 73 and continue with: 734 / 84

Advancing to step 3:
When dividing 734 by 84, we get 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 62 after subtracting 672 from 734.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 84

Let's proceed to step 4:
84 goes into 625 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we subtract 588 from 625, we get 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 84

Advancing to step 5:
84 can be fit into 377 4 times, resulting in a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 874.0
Subtracting 336 from 377 leaves us with 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 84

Step 6:
419 divided by 84 is 4 with a remainder of 83.
The number 4 becomes the next digit in our result. 
Result so far: 8744.0
Subtract 336 from 419 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 7:
84 goes into 830 9 times with a remainder of 74.
Write down 9 as next digit of the result. 
Result so far: 8744.9
Deduct 756 from 830 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 8:
If we divide 740 by 84, we get 8 and a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 8744.98
Deduct 672 from 740 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
84 goes into 680 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 8744.988
If we take 672 away from 680, we end up 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.

The final result is 8744.988 with a remainder of 0.0008.
