We look at the division of 993010 by 19 
The aim is to understand the frequency of 19 in 993010.

On to step 1:
19 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 19

Advancing to step 2:
The number 19 fits into 99 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 4 after subtracting 95 from 99.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 19

Advancing to step 3:
43 divided by 19 is 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 52.0
The remainder is 5 after subtracting 38 from 43.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 19

Let's proceed to step 4:
50 divided by 19 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 522.0
Subtract 38 from 50 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 19

Going ahead to step 5:
When dividing 121 by 19, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 5226.0
Subtracting 114 from 121 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 19

Advancing to step 6:
70 divided by 19 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 52263.0
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.

Advancing to step 7:
19 goes into 130 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 52263.6
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
If we divide 160 by 19, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 52263.68
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 52263.684
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 19, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 52263.6842
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
When dividing 20 by 19, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 52263.68421
Subtract 19 from 20 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.

Let's proceed to step 12:
19 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 52263.68421
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
100 divided by 19 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 52263.6842105
Subtract 95 from 100 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
The number 19 fits into 50 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 52263.68421052
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.

The final outcome is 52263.68421052, with a leftover of 1.2e-08.
