We look at the division of 19412972 by 665 
The aim is to understand the frequency of 665 in 19412972.

Let's proceed to step 1:
If we divide 1 by 665, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 665

Step 2:
The number 665 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 665

Step 3:
665 can be fit into 194 0 times, resulting in a remainder of 194.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 194 leaves us with 194.
Fetch the next digit (1) from the dividend, attach it to 194 and continue: 1941 / 665

Step 4:
665 goes into 1941 2 times with a remainder of 611.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1330 from 1941 leaves us with 611.
Grab the next digit (2) from the dividend, add it to 611, then carry on: 6112 / 665

Going ahead to step 5:
665 can be fit into 6112 9 times, resulting in a remainder of 127.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 5985 from 6112, we get 127.
Grab the next digit (9) from the dividend, add it to 127, then carry on: 1279 / 665

On to step 6:
665 can be fit into 1279 1 times, resulting in a remainder of 614.
Use 1 as the next digit of our solution. 
Result so far: 291.0
Subtract 665 from 1279 to get 614.
Bring next digit (7) of the dividend behind the 614 and repeat the process: 6147 / 665

On to step 7:
665 goes into 6147 9 times with a remainder of 162.
Write down 9 as next digit of the result. 
Result so far: 2919.0
Deduct 5985 from 6147 and we're left with 162.
Include the next digit (2) from the dividend after 162, then repeat: 1622 / 665

Let's proceed to step 8:
665 can be fit into 1622 2 times, resulting in a remainder of 292.
Put 2 as the next digit of the answer. 
Result so far: 29192.0
Subtract 1330 from 1622 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 9:
665 can be fit into 2920 4 times, resulting in a remainder of 260.
The next digit of our result is 4. 
Result so far: 29192.4
If we subtract 2660 from 2920, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 10:
If we divide 2600 by 665, we get 3 and a remainder of 605.
Use 3 as the next digit of our solution. 
Result so far: 29192.43
Subtracting 1995 from 2600 leaves us with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Advancing to step 11:
665 goes into 6050 9 times with a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 29192.439
Subtract 5985 from 6050 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 12:
665 can be fit into 650 0 times, resulting in a remainder of 650.
Write down 0 as next digit of the result. 
Result so far: 29192.439
Deduct 0 from 650 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 13:
6500 divided by 665 is 9 with a remainder of 515.
The next digit of our result is 9. 
Result so far: 29192.43909
The remainder is 515 after subtracting 5985 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 14:
5150 divided by 665 is 7 with a remainder of 495.
The number 7 becomes the next digit in our result. 
Result so far: 29192.439097
Subtracting 4655 from 5150 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 15:
665 can be fit into 4950 7 times, resulting in a remainder of 295.
Record the quotient 7 as the next digit in the result. 
Result so far: 29192.4390977
The remainder is 295 after subtracting 4655 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

In conclusion, the division gives 29192.4390977 with a balance of 2.95e-06.
