We're dividing 151744 by 19 
The aim is to understand the frequency of 19 in 151744.

Step 1:
When dividing 1 by 19, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 19

Going ahead to step 2:
19 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 19

Moving on to step 3:
The number 19 fits into 151 7 times, leaving a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 133 from 151 and we're left with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 19

Moving on to step 4:
19 goes into 187 9 times with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 171 from 187 leaves us with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 19

Step 5:
19 goes into 164 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 798.0
Deduct 152 from 164 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 19

Going ahead to step 6:
19 goes into 124 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 7986.0
If we subtract 114 from 124, we 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.

Let's proceed to step 7:
When dividing 100 by 19, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 7986.5
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.

Going ahead to step 8:
When dividing 50 by 19, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 7986.52
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.

Step 9:
120 divided by 19 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 7986.526
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.

Advancing to step 10:
19 can be fit into 60 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 7986.5263
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 7986.52631
Deduct 19 from 30 and we're left 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.

Going ahead to step 12:
If we divide 110 by 19, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 7986.526315
If we take 95 away from 110, we end up with 15.
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:
The number 19 fits into 150 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 7986.5263157
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.

Step 14:
When dividing 170 by 19, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 7986.52631578
Deduct 152 from 170 and we're left 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.

The final result is 7986.52631578 with a remainder of 1.8e-08.
