We're dividing 132504 by 84 
The aim is to understand the frequency of 84 in 132504.

On to step 1:
84 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 84

On to step 2:
The number 84 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 84

Going ahead to step 3:
132 divided by 84 is 1 with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 84 from 132 and we're left with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 84

Advancing to step 4:
485 divided by 84 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 420 away from 485, we end up with 65.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 84

Going ahead to step 5:
If we divide 650 by 84, we get 7 and a remainder of 62.
The next digit of our result is 7. 
Result so far: 157.0
If we subtract 588 from 650, we get 62.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 84

Advancing to step 6:
624 divided by 84 is 7 with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 1577.0
If we take 588 away from 624, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
When dividing 360 by 84, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1577.4
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
When dividing 240 by 84, we get 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 1577.42
Subtracting 168 from 240 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
The number 84 fits into 720 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1577.428
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
If we divide 480 by 84, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 1577.4285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
600 divided by 84 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 1577.42857
Subtract 588 from 600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
84 goes into 120 1 times with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1577.428571
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
360 divided by 84 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 1577.4285714
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 1577.42857142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 1577.42857142, and the remainder is 7.2e-08.
