We look at the division of 20784771 by 132 
The aim is to understand the frequency of 132 in 20784771.

Advancing to step 1:
132 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 132

Moving on to step 2:
132 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 132

Moving on to step 3:
If we divide 207 by 132, we get 1 and a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 75 after subtracting 132 from 207.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 132

Step 4:
If we divide 758 by 132, we get 5 and a remainder of 98.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 660 from 758 to get 98.
Include the next digit (4) from the dividend after 98, then repeat: 984 / 132

Step 5:
The number 132 fits into 984 7 times, leaving a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 157.0
Subtracting 924 from 984 leaves us with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 132

Going ahead to step 6:
If we divide 607 by 132, we get 4 and a remainder of 79.
Use 4 as the next digit of our solution. 
Result so far: 1574.0
Subtracting 528 from 607 leaves us with 79.
Fetch the next digit (7) from the dividend, attach it to 79 and continue: 797 / 132

Going ahead to step 7:
When dividing 797 by 132, we get 6 with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 15746.0
Deduct 792 from 797 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 132

Step 8:
51 divided by 132 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 157460.0
If we take 0 away from 51, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
132 can be fit into 510 3 times, resulting in a remainder of 114.
Put 3 as the next digit of the answer. 
Result so far: 157460.3
The remainder is 114 after subtracting 396 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
The number 132 fits into 1140 8 times, leaving a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 157460.38
Subtracting 1056 from 1140 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
If we divide 840 by 132, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 157460.386
The remainder is 48 after subtracting 792 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
132 can be fit into 480 3 times, resulting in a remainder of 84.
Use 3 as the next digit of our solution. 
Result so far: 157460.3863
If we take 396 away from 480, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 13:
840 divided by 132 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 157460.38636
Deduct 792 from 840 and we're left 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.

Moving on to step 14:
480 divided by 132 is 3 with a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 157460.386363
Deduct 396 from 480 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 15:
The number 132 fits into 840 6 times, leaving a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 157460.3863636
If we take 792 away from 840, 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.

Moving on to step 16:
When dividing 480 by 132, we get 3 with a remainder of 84.
The next digit of our result is 3. 
Result so far: 157460.38636363
If we take 396 away from 480, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 157460.38636363 with a remainder of 8.4e-08.
