Let's divide 751241 by 19
The aim is to understand the frequency of 19 in 751241.

Going ahead to step 1:
If we divide 7 by 19, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 19

Advancing to step 2:
The number 19 fits into 75 3 times, leaving a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 57 from 75 and we're left with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 19

Advancing to step 3:
If we divide 181 by 19, we get 9 and a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 171 from 181 leaves us with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 19

Moving on to step 4:
19 goes into 102 5 times with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 395.0
Subtract 95 from 102 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 19

Step 5:
19 can be fit into 74 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3953.0
The remainder is 17 after subtracting 57 from 74.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 19

Let's proceed to step 6:
171 divided by 19 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 39539.0
The remainder is 0 after subtracting 171 from 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
If we divide 0 by 19, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 39539.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 19 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39539.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 39539.0 with a remainder of 0.0.
