Let's divide 216232 by 19
The aim is to understand the frequency of 19 in 216232.

Advancing 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
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 19

Advancing to step 2:
The number 19 fits into 21 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 19 away from 21, we end up with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 19

Step 3:
26 divided by 19 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 19 from 26 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 19

On to step 4:
72 divided by 19 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we take 57 away from 72, we end up with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 19

Advancing to step 5:
153 divided by 19 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1138.0
Deduct 152 from 153 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 19

On to step 6:
12 divided by 19 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 11380.0
If we subtract 0 from 12, 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 7:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 11380.6
Subtracting 114 from 120 leaves us 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.

Let's proceed to step 8:
60 divided by 19 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 11380.63
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.

Step 9:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 11380.631
If we take 19 away from 30, we end up 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.

Step 10:
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: 11380.6315
The remainder is 15 after subtracting 95 from 110.
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 11:
When dividing 150 by 19, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 11380.63157
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.

Advancing to step 12:
When dividing 170 by 19, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 11380.631578
If we subtract 152 from 170, we 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 13:
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: 11380.6315789
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
If we divide 90 by 19, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 11380.63157894
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.

After the division, we end up with 11380.63157894 and a remainder of 1.4e-08.
