We're dividing 742544 by 19 
The aim is to understand the frequency of 19 in 742544.

Going ahead to step 1:
19 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 19

On to step 2:
When dividing 74 by 19, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 17 after subtracting 57 from 74.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 19

Step 3:
19 goes into 172 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 171 from 172 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 19

Advancing to step 4:
15 divided by 19 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 390.0
If we subtract 0 from 15, we get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 19

Moving on to step 5:
When dividing 154 by 19, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 3908.0
Deduct 152 from 154 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 19

Moving on to step 6:
When dividing 24 by 19, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 39081.0
If we subtract 19 from 24, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 39081.2
Subtracting 38 from 50 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
120 divided by 19 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 39081.26
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
19 can be fit into 60 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 39081.263
If we take 57 away from 60, we end up 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.

Let's proceed to step 10:
When dividing 30 by 19, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 39081.2631
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
19 can be fit into 110 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 39081.26315
If we take 95 away from 110, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
When dividing 150 by 19, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 39081.263157
Subtracting 133 from 150 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 39081.2631578
Subtracting 152 from 170 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 39081.26315789
If we take 171 away from 180, 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.

The final result is 39081.26315789 with a remainder of 9e-09.
