905858 ÷ 84 
The aim is to understand the frequency of 84 in 905858.

Let's proceed to step 1:
If we divide 9 by 84, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 84

On to step 2:
The number 84 fits into 90 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 84 from 90, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 84

Going ahead to step 3:
If we divide 65 by 84, we get 0 and a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 65 leaves us with 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 84

On to step 4:
If we divide 658 by 84, we get 7 and a remainder of 70.
The next digit of our result is 7. 
Result so far: 107.0
Subtracting 588 from 658 leaves us with 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 84

On to step 5:
If we divide 705 by 84, we get 8 and a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 1078.0
Subtract 672 from 705 to get 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 84

Advancing to step 6:
When dividing 338 by 84, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 10784.0
If we subtract 336 from 338, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 84, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10784.0
If we take 0 away from 20, we end up 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 8:
When dividing 200 by 84, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 10784.02
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.

Advancing to step 9:
320 divided by 84 is 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 10784.023
If we subtract 252 from 320, we 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.

Going ahead to step 10:
When dividing 680 by 84, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 10784.0238
Subtract 672 from 680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
84 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10784.0238
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.

On to 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: 10784.023809
Subtracting 756 from 800 leaves us 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.

Let's proceed to step 13:
84 can be fit into 440 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 10784.0238095
If we take 420 away from 440, we end up 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 14:
If we divide 200 by 84, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 10784.02380952
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.

Our division results in 10784.02380952 with a remaining 3.2e-08.
