We look at the division of 347993 by 19 
The aim is to understand the frequency of 19 in 347993.

On to step 1:
19 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 19

On to step 2:
When dividing 34 by 19, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 15 after subtracting 19 from 34.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 19

Advancing to step 3:
When dividing 157 by 19, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 152 from 157 to get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 19

On to step 4:
19 can be fit into 59 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 183.0
If we subtract 57 from 59, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 19

Let's proceed to step 5:
19 goes into 29 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1831.0
If we take 19 away from 29, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 19

Let's proceed to step 6:
103 divided by 19 is 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 18315.0
Subtract 95 from 103 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
When dividing 80 by 19, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 18315.4
If we take 76 away from 80, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
If we divide 40 by 19, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 18315.42
Subtracting 38 from 40 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
When dividing 20 by 19, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 18315.421
Subtracting 19 from 20 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
10 divided by 19 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 18315.421
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
100 divided by 19 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 18315.42105
If we take 95 away from 100, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
50 divided by 19 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 18315.421052
Deduct 38 from 50 and we're left 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.

On to step 13:
The number 19 fits into 120 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 18315.4210526
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 14:
When dividing 60 by 19, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 18315.42105263
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.

The final result is 18315.42105263 with a remainder of 3e-09.
