We look at the division of 904835 by 84 
The aim is to understand the frequency of 84 in 904835.

Let's proceed to step 1:
The number 84 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 84

Let's proceed to step 2:
84 goes into 90 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 84 from 90 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 84

Step 3:
64 divided by 84 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 84

Going ahead to step 4:
84 goes into 648 7 times with a remainder of 60.
The next digit of our result is 7. 
Result so far: 107.0
Subtract 588 from 648 to get 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 84

Moving on to step 5:
84 goes into 603 7 times with a remainder of 15.
The next digit of our result is 7. 
Result so far: 1077.0
Deduct 588 from 603 and we're left with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 84

Advancing to step 6:
84 can be fit into 155 1 times, resulting in a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 10771.0
If we subtract 84 from 155, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 7:
When dividing 710 by 84, we get 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 10771.8
Deduct 672 from 710 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
380 divided by 84 is 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 10771.84
Subtract 336 from 380 to get 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 9:
84 goes into 440 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 10771.845
If we subtract 420 from 440, we 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.

Advancing to step 10:
When dividing 200 by 84, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 10771.8452
Deduct 168 from 200 and we're left 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.

Let's proceed to step 11:
The number 84 fits into 320 3 times, leaving a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 10771.84523
Subtracting 252 from 320 leaves us 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.

On to step 12:
When dividing 680 by 84, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10771.845238
The remainder is 8 after subtracting 672 from 680.
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 13:
When dividing 80 by 84, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10771.845238
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.

Moving on to step 14:
800 divided by 84 is 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 10771.84523809
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.

The final outcome is 10771.84523809, with a leftover of 4.4e-08.
