We're dividing 928579 by 84 
The aim is to understand the frequency of 84 in 928579.

Step 1:
9 divided by 84 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 84

Step 2:
84 can be fit into 92 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 84 away from 92, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 84

Going ahead to step 3:
If we divide 88 by 84, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 84 from 88 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 84

Advancing to step 4:
If we divide 45 by 84, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 110.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 84

Step 5:
84 goes into 457 5 times with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 1105.0
Subtract 420 from 457 to get 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 84

Going ahead to step 6:
If we divide 379 by 84, we get 4 and a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 11054.0
If we take 336 away from 379, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
The number 84 fits into 430 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11054.5
If we take 420 away from 430, we end up 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.

Going ahead to step 8:
84 can be fit into 100 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 11054.51
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.

Going ahead to step 9:
When dividing 160 by 84, we get 1 with a remainder of 76.
The next digit of our result is 1. 
Result so far: 11054.511
If we subtract 84 from 160, we 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.

After the division, we end up with 11054.511 and a remainder of 0.0076.
