We divide 311489 by 19
The aim is to understand the frequency of 19 in 311489.

Step 1:
If we divide 3 by 19, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 19

Advancing to step 2:
When dividing 31 by 19, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 19 away from 31, we end up with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 19

Let's proceed to step 3:
The number 19 fits into 121 6 times, leaving a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 114 from 121 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 19

Going ahead to step 4:
The number 19 fits into 74 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
If we take 57 away from 74, we end up with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 19

Advancing to step 5:
178 divided by 19 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 1639.0
Deduct 171 from 178 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 19

Advancing to step 6:
If we divide 79 by 19, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 16394.0
Deduct 76 from 79 and we're left 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.

On to step 7:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 16394.1
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
110 divided by 19 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 16394.15
Subtracting 95 from 110 leaves us 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.

Step 9:
If we divide 150 by 19, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 16394.157
Subtract 133 from 150 to 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.

Moving on to step 10:
170 divided by 19 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 16394.1578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 16394.15789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
If we divide 90 by 19, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 16394.157894
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.

Let's proceed to step 13:
19 can be fit into 140 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 16394.1578947
If we take 133 away from 140, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 16394.15789473
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 16394.15789473 with a remainder of 1.3e-08.
