We're dividing 141999 by 19 
The aim is to understand the frequency of 19 in 141999.

Going ahead to step 1:
1 divided by 19 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 19

Let's proceed to step 2:
14 divided by 19 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 19

Going ahead to step 3:
When dividing 141 by 19, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 8 after subtracting 133 from 141.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 19

Let's proceed to step 4:
When dividing 89 by 19, we get 4 with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 76 from 89 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 19

Moving on to step 5:
139 divided by 19 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 747.0
Deduct 133 from 139 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 19

Moving on to step 6:
The number 19 fits into 69 3 times, leaving a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 7473.0
If we subtract 57 from 69, 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.

Advancing to step 7:
If we divide 120 by 19, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 7473.6
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 19, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 7473.63
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.

Moving on to step 9:
30 divided by 19 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 7473.631
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
19 goes into 110 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7473.6315
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
When dividing 150 by 19, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 7473.63157
If we subtract 133 from 150, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
When dividing 170 by 19, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 7473.631578
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.

Moving on to step 13:
19 can be fit into 180 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 7473.6315789
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
19 can be fit into 90 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 7473.63157894
Subtracting 76 from 90 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 7473.63157894, and the remainder is 1.4e-08.
