Let's divide 121350 by 19
The aim is to understand the frequency of 19 in 121350.

Moving on to step 1:
When dividing 1 by 19, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 19

Advancing to step 2:
19 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 19

Going ahead to step 3:
The number 19 fits into 121 6 times, leaving a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 7 after subtracting 114 from 121.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 19

Step 4:
19 can be fit into 73 3 times, resulting in a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we take 57 away from 73, we end up with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 19

Going ahead to step 5:
19 can be fit into 165 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 638.0
If we take 152 away from 165, we end up with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 19

Step 6:
When dividing 130 by 19, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 6386.0
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
If we divide 160 by 19, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 6386.8
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.

Going ahead to step 8:
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: 6386.84
Deduct 76 from 80 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 6386.842
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
The number 19 fits into 20 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 6386.8421
If we subtract 19 from 20, we 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 11:
The number 19 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 6386.8421
Subtract 0 from 10 to 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 12:
When dividing 100 by 19, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6386.842105
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.

Moving on to step 13:
50 divided by 19 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 6386.8421052
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.

Let's proceed to step 14:
When dividing 120 by 19, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 6386.84210526
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 6386.84210526 with a remaining 6e-09.
