Let's divide 723524 by 84
The aim is to understand the frequency of 84 in 723524.

Step 1:
84 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 84

Going ahead to step 2:
72 divided by 84 is 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Fetch the next digit (3) from the dividend, attach it to 72 and continue: 723 / 84

Step 3:
When dividing 723 by 84, we get 8 with a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 672 from 723 and we're left with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 84

Step 4:
If we divide 515 by 84, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Subtract 504 from 515 to get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 84

Going ahead to step 5:
84 goes into 112 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 861.0
Deduct 84 from 112 and we're left with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 84

Let's proceed to step 6:
The number 84 fits into 284 3 times, leaving a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 8613.0
Deduct 252 from 284 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
The number 84 fits into 320 3 times, leaving a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 8613.3
Deduct 252 from 320 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.

Step 8:
The number 84 fits into 680 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 8613.38
If we subtract 672 from 680, we get 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 9:
If we divide 80 by 84, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 8613.38
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.

Let's proceed to step 10:
84 can be fit into 800 9 times, resulting in a remainder of 44.
The next digit of our result is 9. 
Result so far: 8613.3809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
If we divide 440 by 84, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 8613.38095
The remainder is 20 after subtracting 420 from 440.
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 12:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 8613.380952
Subtracting 168 from 200 leaves us with 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 13:
84 can be fit into 320 3 times, resulting in a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 8613.3809523
Deduct 252 from 320 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.

On to step 14:
The number 84 fits into 680 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 8613.38095238
The remainder is 8 after subtracting 672 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 8613.38095238 with a balance of 8e-09.
