Let's divide 159005 by 19
The aim is to understand the frequency of 19 in 159005.

Step 1:
The number 19 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 19

Moving on to step 2:
The number 19 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 19

Moving on to step 3:
When dividing 159 by 19, we get 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 152 from 159 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 19

Let's proceed to step 4:
The number 19 fits into 70 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 83.0
Deduct 57 from 70 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 19

Going ahead to step 5:
When dividing 130 by 19, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 836.0
Subtracting 114 from 130 leaves us with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 19

On to step 6:
The number 19 fits into 165 8 times, leaving a remainder of 13.
The next digit of our result is 8. 
Result so far: 8368.0
Subtract 152 from 165 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
19 can be fit into 130 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 8368.6
If we take 114 away from 130, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
19 goes into 160 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8368.68
If we subtract 152 from 160, we 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.

On to step 9:
80 divided by 19 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 8368.684
Deduct 76 from 80 and we're left 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 10:
When dividing 40 by 19, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 8368.6842
If we take 38 away from 40, we end up 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.

Step 11:
19 goes into 20 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 8368.68421
If we subtract 19 from 20, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
If we divide 10 by 19, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 8368.68421
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
If we divide 100 by 19, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 8368.6842105
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.

On to step 14:
The number 19 fits into 50 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 8368.68421052
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.

Our division results in 8368.68421052 with a remaining 1.2e-08.
