803881 divided by 84 
The aim is to understand the frequency of 84 in 803881.

On to step 1:
84 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 84

On to step 2:
84 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 84

Step 3:
84 can be fit into 803 9 times, resulting in a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 47 after subtracting 756 from 803.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 84

Step 4:
If we divide 478 by 84, we get 5 and a remainder of 58.
Write down 5 as next digit of the result. 
Result so far: 95.0
The remainder is 58 after subtracting 420 from 478.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 84

On to step 5:
If we divide 588 by 84, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 957.0
Subtract 588 from 588 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 84

Moving on to step 6:
84 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 9570.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 84 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9570.0
Deduct 0 from 10 and we're left 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.

On 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: 9570.01
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:
If we divide 160 by 84, we get 1 and a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 9570.011
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 outcome is 9570.011, with a leftover of 0.0076.
