753251 divided by 84 
The aim is to understand the frequency of 84 in 753251.

Let's proceed to step 1:
84 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 84

Step 2:
When dividing 75 by 84, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 84

Step 3:
The number 84 fits into 753 8 times, leaving a remainder of 81.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 672 from 753, we get 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 84

Step 4:
84 goes into 812 9 times with a remainder of 56.
The next digit of our result is 9. 
Result so far: 89.0
The remainder is 56 after subtracting 756 from 812.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 84

Advancing to step 5:
84 goes into 565 6 times with a remainder of 61.
Write down 6 as next digit of the result. 
Result so far: 896.0
The remainder is 61 after subtracting 504 from 565.
Take the next digit (1) from the dividend and append it to 61, then repeat: 611 / 84

Moving on to step 6:
84 goes into 611 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 8967.0
Subtracting 588 from 611 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
When dividing 230 by 84, we get 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 8967.2
Subtracting 168 from 230 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
84 can be fit into 620 7 times, resulting in a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 8967.27
Subtract 588 from 620 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
The number 84 fits into 320 3 times, leaving a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 8967.273
If we subtract 252 from 320, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
680 divided by 84 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 8967.2738
Subtract 672 from 680 to 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.

Step 11:
80 divided by 84 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 8967.2738
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
If we divide 800 by 84, we get 9 and a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 8967.273809
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
The number 84 fits into 440 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 8967.2738095
Subtracting 420 from 440 leaves us with 20.
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 14:
If we divide 200 by 84, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 8967.27380952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 8967.27380952, with a leftover of 3.2e-08.
