We're dividing 730288 by 84 
The aim is to understand the frequency of 84 in 730288.

Step 1:
7 divided by 84 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 84

Step 2:
84 can be fit into 73 0 times, resulting in a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 84

Step 3:
84 goes into 730 8 times with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 672 from 730, we get 58.
Take the next digit (2) from the dividend and append it to 58, then repeat: 582 / 84

Going ahead to step 4:
The number 84 fits into 582 6 times, leaving a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtract 504 from 582 to get 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 84

Moving on to step 5:
788 divided by 84 is 9 with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 869.0
If we take 756 away from 788, we end up with 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 84

On to step 6:
328 divided by 84 is 3 with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 8693.0
Subtract 252 from 328 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 7:
84 can be fit into 760 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 8693.9
Deduct 756 from 760 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
84 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 8693.9
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
If we divide 400 by 84, we get 4 and a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 8693.904
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
84 goes into 640 7 times with a remainder of 52.
The next digit of our result is 7. 
Result so far: 8693.9047
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
The number 84 fits into 520 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 8693.90476
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
84 can be fit into 160 1 times, resulting in a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 8693.904761
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
If we divide 760 by 84, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 8693.9047619
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
The number 84 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 8693.9047619
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 8693.9047619 and a remainder of 4e-08.
