352018 divided by 19 
The aim is to understand the frequency of 19 in 352018.

Step 1:
If we divide 3 by 19, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 19

Advancing to step 2:
19 goes into 35 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 19 from 35, we get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 19

Moving on to step 3:
The number 19 fits into 162 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 152 from 162, we get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 19

On to step 4:
If we divide 100 by 19, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Subtract 95 from 100 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 19

Advancing to step 5:
If we divide 51 by 19, we get 2 and a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 1852.0
Deduct 38 from 51 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 19

Step 6:
19 can be fit into 138 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 18527.0
The remainder is 5 after subtracting 133 from 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 18527.2
Deduct 38 from 50 and we're left with 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 8:
19 can be fit into 120 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 18527.26
If we subtract 114 from 120, we 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:
60 divided by 19 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 18527.263
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
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: 18527.2631
Subtract 19 from 30 to 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.

On to step 11:
19 goes into 110 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 18527.26315
If we subtract 95 from 110, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
The number 19 fits into 150 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 18527.263157
If we subtract 133 from 150, we 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.

Step 13:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 18527.2631578
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 14:
19 goes into 180 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 18527.26315789
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.

The final outcome is 18527.26315789, with a leftover of 9e-09.
