16685326 ÷ 19 
The aim is to understand the frequency of 19 in 16685326.

Moving on to step 1:
1 divided by 19 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 19

Let's proceed to step 2:
19 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 19

Moving on to step 3:
If we divide 166 by 19, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 152 from 166, we get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 19

Step 4:
148 divided by 19 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtracting 133 from 148 leaves us with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 19

Step 5:
19 can be fit into 155 8 times, resulting in a remainder of 3.
The next digit of our result is 8. 
Result so far: 878.0
Subtracting 152 from 155 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 19

Going ahead to step 6:
The number 19 fits into 33 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 8781.0
Deduct 19 from 33 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 19

Moving on to step 7:
The number 19 fits into 142 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 87817.0
Deduct 133 from 142 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 19

Step 8:
The number 19 fits into 96 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 878175.0
Subtract 95 from 96 to 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.

Going ahead to step 9:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 878175.0
If we take 0 away from 10, we end up 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.

Let's proceed to step 10:
19 can be fit into 100 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 878175.05
Deduct 95 from 100 and we're left with 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 11:
50 divided by 19 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 878175.052
If we subtract 38 from 50, we 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.

Step 12:
19 goes into 120 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 878175.0526
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
19 can be fit into 60 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 878175.05263
Deduct 57 from 60 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.

Going ahead to step 14:
If we divide 30 by 19, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 878175.052631
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.

Advancing to step 15:
When dividing 110 by 19, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 878175.0526315
Deduct 95 from 110 and we're left 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 16:
19 goes into 150 7 times with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 878175.05263157
Subtracting 133 from 150 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 878175.05263157, and the remainder is 1.7e-08.
