We're dividing 657044 by 84 
The aim is to understand the frequency of 84 in 657044.

Moving on to step 1:
84 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 84

Going ahead to step 2:
When dividing 65 by 84, we get 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 84

Step 3:
The number 84 fits into 657 7 times, leaving a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 588 away from 657, we end up with 69.
Include the next digit (0) from the dividend after 69, then repeat: 690 / 84

On to step 4:
If we divide 690 by 84, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 78.0
The remainder is 18 after subtracting 672 from 690.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 84

Let's proceed to step 5:
84 goes into 184 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 782.0
The remainder is 16 after subtracting 168 from 184.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 84

Let's proceed to step 6:
164 divided by 84 is 1 with a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 7821.0
If we subtract 84 from 164, 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.

On to step 7:
84 can be fit into 800 9 times, resulting in a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 7821.9
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 8:
84 goes into 440 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 7821.95
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.

On to step 9:
When dividing 200 by 84, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 7821.952
The remainder is 32 after subtracting 168 from 200.
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 10:
320 divided by 84 is 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 7821.9523
Deduct 252 from 320 and we're left 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.

Let's proceed to step 11:
The number 84 fits into 680 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 7821.95238
If we take 672 away from 680, we end up 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.

Going ahead to step 12:
84 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 7821.95238
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 13:
84 can be fit into 800 9 times, resulting in a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 7821.9523809
If we subtract 756 from 800, we 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.

Step 14:
If we divide 440 by 84, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 7821.95238095
Subtract 420 from 440 to 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.

The final outcome is 7821.95238095, with a leftover of 2e-08.
