We look at the division of 20509540 by 192 
The aim is to understand the frequency of 192 in 20509540.

Step 1:
2 divided by 192 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 192

On to step 2:
The number 192 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 192

Going ahead to step 3:
The number 192 fits into 205 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 192 from 205 to get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 192

Step 4:
The number 192 fits into 130 0 times, leaving a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 130 and we're left with 130.
Fetch the next digit (9) from the dividend, attach it to 130 and continue: 1309 / 192

Moving on to step 5:
If we divide 1309 by 192, we get 6 and a remainder of 157.
The next digit of our result is 6. 
Result so far: 106.0
Subtract 1152 from 1309 to get 157.
Bring next digit (5) of the dividend behind the 157 and repeat the process: 1575 / 192

Let's proceed to step 6:
The number 192 fits into 1575 8 times, leaving a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 1068.0
Subtracting 1536 from 1575 leaves us with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 192

Going ahead to step 7:
192 can be fit into 394 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 10682.0
Subtracting 384 from 394 leaves us with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 192

Moving on to step 8:
If we divide 100 by 192, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 106820.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 9:
192 can be fit into 1000 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 106820.5
Subtract 960 from 1000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
400 divided by 192 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 106820.52
If we take 384 away from 400, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
If we divide 160 by 192, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 106820.52
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
1600 divided by 192 is 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 106820.5208
Deduct 1536 from 1600 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
If we divide 640 by 192, we get 3 and a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 106820.52083
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
If we divide 640 by 192, we get 3 and a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 106820.520833
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 106820.520833, with a leftover of 6.4e-06.
