726937 divided by 84 
The aim is to understand the frequency of 84 in 726937.

On to step 1:
84 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 84

Let's proceed to step 2:
The number 84 fits into 72 0 times, leaving a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Take the next digit (6) from the dividend and append it to 72, then repeat: 726 / 84

On to step 3:
726 divided by 84 is 8 with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 54 after subtracting 672 from 726.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 84

Going ahead to step 4:
The number 84 fits into 549 6 times, leaving a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 504 from 549 leaves us with 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 84

Going ahead to step 5:
84 goes into 453 5 times with a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 865.0
Deduct 420 from 453 and we're left with 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 84

Going ahead to step 6:
337 divided by 84 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 8654.0
Subtracting 336 from 337 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 84, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 8654.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 84, we get 1 and a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 8654.01
If we subtract 84 from 100, we get 16.
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 9:
When dividing 160 by 84, we get 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 8654.011
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.

The final outcome is 8654.011, with a leftover of 0.0076.
