372942 ÷ 19 
The aim is to understand the frequency of 19 in 372942.

Advancing to step 1:
If we divide 3 by 19, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 19

Let's proceed to step 2:
19 can be fit into 37 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 19 from 37 to get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 19

Let's proceed to step 3:
182 divided by 19 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 171 from 182 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 19

Moving on to step 4:
When dividing 119 by 19, we get 6 with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
If we take 114 away from 119, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 19

Moving on to step 5:
19 can be fit into 54 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1962.0
The remainder is 16 after subtracting 38 from 54.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 19

Advancing to step 6:
19 goes into 162 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 19628.0
Subtract 152 from 162 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
19 can be fit into 100 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 19628.5
The remainder is 5 after subtracting 95 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
50 divided by 19 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 19628.52
If we subtract 38 from 50, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 19628.526
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
If we divide 60 by 19, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 19628.5263
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
19 goes into 30 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 19628.52631
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.

Moving on to step 12:
When dividing 110 by 19, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 19628.526315
The remainder is 15 after subtracting 95 from 110.
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 13:
150 divided by 19 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 19628.5263157
The remainder is 17 after subtracting 133 from 150.
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 14:
19 goes into 170 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 19628.52631578
If we subtract 152 from 170, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 19628.52631578 with a balance of 1.8e-08.
