491317 divided by 84 
The aim is to understand the frequency of 84 in 491317.

On to step 1:
4 divided by 84 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 84

Advancing to step 2:
The number 84 fits into 49 0 times, leaving a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 84

Let's proceed to step 3:
The number 84 fits into 491 5 times, leaving a remainder of 71.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 420 from 491 and we're left with 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 84

Going ahead to step 4:
713 divided by 84 is 8 with a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Subtract 672 from 713 to get 41.
Fetch the next digit (1) from the dividend, attach it to 41 and continue: 411 / 84

Advancing to step 5:
If we divide 411 by 84, we get 4 and a remainder of 75.
The next digit of our result is 4. 
Result so far: 584.0
The remainder is 75 after subtracting 336 from 411.
Fetch the next digit (7) from the dividend, attach it to 75 and continue: 757 / 84

Step 6:
84 can be fit into 757 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 5849.0
If we take 756 away from 757, we end up 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.

On 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: 5849.0
Subtract 0 from 10 to get 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:
84 can be fit into 100 1 times, resulting in a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 5849.01
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
160 divided by 84 is 1 with a remainder of 76.
The next digit of our result is 1. 
Result so far: 5849.011
Subtract 84 from 160 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.

The final result is 5849.011 with a remainder of 0.0076.
