Let's divide 210164 by 19
The aim is to understand the frequency of 19 in 210164.

On to step 1:
2 divided by 19 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 19

Moving on to step 2:
19 goes into 21 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 19 from 21 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 19

Advancing to step 3:
If we divide 20 by 19, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 19 from 20 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 19

Going ahead to step 4:
If we divide 11 by 19, we get 0 and a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 110.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 19

Going ahead to step 5:
116 divided by 19 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 1106.0
Deduct 114 from 116 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 19

Going ahead to step 6:
24 divided by 19 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 11061.0
If we take 19 away from 24, we end up 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 7:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 11061.2
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.

Advancing to step 8:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 11061.26
Subtract 114 from 120 to get 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 9:
When dividing 60 by 19, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 11061.263
If we take 57 away from 60, we end up 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.

Let's proceed to step 10:
When dividing 30 by 19, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 11061.2631
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.

Advancing to step 11:
The number 19 fits into 110 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 11061.26315
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 12:
19 can be fit into 150 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 11061.263157
If we take 133 away from 150, we end up 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.

On to step 13:
170 divided by 19 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 11061.2631578
Subtract 152 from 170 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
19 goes into 180 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 11061.26315789
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.

Our division results in 11061.26315789 with a remaining 9e-09.
