We divide 833891 by 84
The aim is to understand the frequency of 84 in 833891.

Going ahead to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 84

Moving on to step 2:
83 divided by 84 is 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Bring next digit (3) of the dividend behind the 83 and repeat the process: 833 / 84

Going ahead to step 3:
If we divide 833 by 84, we get 9 and a remainder of 77.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 756 from 833 to get 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 84

Moving on to step 4:
84 goes into 778 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtract 756 from 778 to get 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 84

Advancing to step 5:
When dividing 229 by 84, we get 2 with a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 992.0
Subtract 168 from 229 to get 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 84

On to step 6:
84 can be fit into 611 7 times, resulting in a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 9927.0
Subtract 588 from 611 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
84 can be fit into 230 2 times, resulting in a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 9927.2
If we subtract 168 from 230, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
620 divided by 84 is 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 9927.27
The remainder is 32 after subtracting 588 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
When dividing 320 by 84, we get 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 9927.273
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 10:
84 goes into 680 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 9927.2738
Deduct 672 from 680 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
84 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 9927.2738
If we take 0 away from 80, we end up 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.

Step 12:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 9927.273809
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.

Moving on to step 13:
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: 9927.2738095
Subtract 420 from 440 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
If we divide 200 by 84, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 9927.27380952
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 9927.27380952, with a leftover of 3.2e-08.
