We look at the division of 155471 by 19 
The aim is to understand the frequency of 19 in 155471.

Going ahead to step 1:
1 divided by 19 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 19

Going ahead to step 2:
If we divide 15 by 19, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 19

Let's proceed to step 3:
The number 19 fits into 155 8 times, leaving a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 152 from 155, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 19

On to step 4:
The number 19 fits into 34 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Deduct 19 from 34 and we're left with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 19

Going ahead to step 5:
When dividing 157 by 19, we get 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 818.0
Subtract 152 from 157 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 19

Step 6:
19 can be fit into 51 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 8182.0
The remainder is 13 after subtracting 38 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 19, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 8182.6
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8182.68
If we take 152 away from 160, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
If we divide 80 by 19, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 8182.684
Subtracting 76 from 80 leaves us 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.

On to step 10:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 8182.6842
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.

Let's proceed to step 11:
19 can be fit into 20 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 8182.68421
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:
10 divided by 19 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 8182.68421
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.

Step 13:
19 goes into 100 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 8182.6842105
Subtract 95 from 100 to 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.

Advancing to step 14:
50 divided by 19 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 8182.68421052
Subtract 38 from 50 to 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.

The final outcome is 8182.68421052, with a leftover of 1.2e-08.
