Let's divide 311907 by 19
The aim is to understand the frequency of 19 in 311907.

Moving on to step 1:
When dividing 3 by 19, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 19

On to step 2:
The number 19 fits into 31 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 19 away from 31, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 19

Step 3:
19 can be fit into 121 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 114 from 121 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 19

Advancing to step 4:
79 divided by 19 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 164.0
If we subtract 76 from 79, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 19

Going ahead to step 5:
When dividing 30 by 19, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1641.0
If we subtract 19 from 30, we get 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 19

Let's proceed to step 6:
When dividing 117 by 19, we get 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 16416.0
The remainder is 3 after subtracting 114 from 117.
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:
When dividing 30 by 19, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 16416.1
If we subtract 19 from 30, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
19 can be fit into 110 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 16416.15
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.

On to step 9:
19 goes into 150 7 times with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 16416.157
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.

Let's proceed to step 10:
19 can be fit into 170 8 times, resulting in a remainder of 18.
The next digit of our result is 8. 
Result so far: 16416.1578
If we take 152 away from 170, we end up 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 11:
If we divide 180 by 19, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 16416.15789
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.

Going ahead to step 12:
19 goes into 90 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 16416.157894
Deduct 76 from 90 and we're left 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.

Going ahead 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: 16416.1578947
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.

Going ahead to step 14:
70 divided by 19 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 16416.15789473
Subtracting 57 from 70 leaves us 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.

In conclusion, the division gives 16416.15789473 with a balance of 1.3e-08.
