856280 ÷ 84 
The aim is to understand the frequency of 84 in 856280.

Advancing to step 1:
84 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 84

Going ahead to step 2:
85 divided by 84 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 84 from 85 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 84

Moving on to step 3:
84 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 84

Advancing to step 4:
162 divided by 84 is 1 with a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 84 from 162 and we're left with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 84

Going ahead to step 5:
If we divide 788 by 84, we get 9 and a remainder of 32.
The next digit of our result is 9. 
Result so far: 1019.0
The remainder is 32 after subtracting 756 from 788.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 84

Let's proceed to step 6:
320 divided by 84 is 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 10193.0
Subtract 252 from 320 to 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.

Step 7:
If we divide 680 by 84, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 10193.8
Subtracting 672 from 680 leaves us 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.

On to step 8:
80 divided by 84 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 10193.8
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 10193.809
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 10:
84 can be fit into 440 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 10193.8095
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.

Let's proceed to step 11:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10193.80952
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
84 can be fit into 320 3 times, resulting in a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 10193.809523
Subtract 252 from 320 to 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.

Advancing to step 13:
The number 84 fits into 680 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 10193.8095238
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.

Moving on to step 14:
80 divided by 84 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 10193.8095238
Deduct 0 from 80 and we're left 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.

The final result is 10193.8095238 with a remainder of 8e-08.
