73449 ÷ 51 
The aim is to understand the frequency of 51 in 73449.

Going ahead to step 1:
7 divided by 51 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 51

Going ahead to step 2:
When dividing 73 by 51, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 51 from 73 leaves us with 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 51

Let's proceed to step 3:
51 can be fit into 224 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 204 from 224 to get 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 51

Going ahead to step 4:
204 divided by 51 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we subtract 204 from 204, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 51

Step 5:
51 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 1440.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 6:
51 goes into 90 1 times with a remainder of 39.
The next digit of our result is 1. 
Result so far: 1440.1
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
390 divided by 51 is 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 1440.17
If we take 357 away from 390, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 8:
51 goes into 330 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 1440.176
Subtract 306 from 330 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.

Advancing to step 9:
51 can be fit into 240 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 1440.1764
The remainder is 36 after subtracting 204 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
51 can be fit into 360 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 1440.17647
Subtracting 357 from 360 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
51 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1440.17647
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
The number 51 fits into 300 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 1440.1764705
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
450 divided by 51 is 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 1440.17647058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 1440.17647058 with a remainder of 4.2e-08.
