We look at the division of 51439745 by 132 
The aim is to understand the frequency of 132 in 51439745.

Step 1:
When dividing 5 by 132, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 132

Moving on to step 2:
If we divide 51 by 132, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 132

Let's proceed to step 3:
If we divide 514 by 132, we get 3 and a remainder of 118.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 396 from 514 leaves us with 118.
Append the next digit (3) from the dividend to 118 and continue with: 1183 / 132

Moving on to step 4:
When dividing 1183 by 132, we get 8 with a remainder of 127.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtracting 1056 from 1183 leaves us with 127.
Grab the next digit (9) from the dividend, add it to 127, then carry on: 1279 / 132

Moving on to step 5:
If we divide 1279 by 132, we get 9 and a remainder of 91.
Put 9 as the next digit of the answer. 
Result so far: 389.0
Subtracting 1188 from 1279 leaves us with 91.
Grab the next digit (7) from the dividend, add it to 91, then carry on: 917 / 132

Step 6:
132 can be fit into 917 6 times, resulting in a remainder of 125.
Write down 6 as next digit of the result. 
Result so far: 3896.0
The remainder is 125 after subtracting 792 from 917.
Grab the next digit (4) from the dividend, add it to 125, then carry on: 1254 / 132

Advancing to step 7:
132 goes into 1254 9 times with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 38969.0
If we subtract 1188 from 1254, we get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 132

Going ahead to step 8:
The number 132 fits into 665 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 389695.0
Deduct 660 from 665 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
The number 132 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 389695.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
132 goes into 500 3 times with a remainder of 104.
Write down 3 as next digit of the result. 
Result so far: 389695.03
The remainder is 104 after subtracting 396 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 11:
If we divide 1040 by 132, we get 7 and a remainder of 116.
Record the quotient 7 as the next digit in the result. 
Result so far: 389695.037
Deduct 924 from 1040 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 12:
When dividing 1160 by 132, we get 8 with a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 389695.0378
If we take 1056 away from 1160, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 13:
132 can be fit into 1040 7 times, resulting in a remainder of 116.
The number 7 becomes the next digit in our result. 
Result so far: 389695.03787
The remainder is 116 after subtracting 924 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 14:
132 can be fit into 1160 8 times, resulting in a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 389695.037878
If we take 1056 away from 1160, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 15:
If we divide 1040 by 132, we get 7 and a remainder of 116.
Write down 7 as next digit of the result. 
Result so far: 389695.0378787
Subtract 924 from 1040 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 16:
1160 divided by 132 is 8 with a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 389695.03787878
The remainder is 104 after subtracting 1056 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 389695.03787878 and a remainder of 1.04e-07.
