We divide 19621 by 19
The aim is to understand the frequency of 19 in 19621.

Moving on to step 1:
If we divide 1 by 19, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 19

Let's proceed to step 2:
19 goes into 19 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 19 from 19, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 19

Moving on to step 3:
If we divide 6 by 19, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 19

Let's proceed to step 4:
19 goes into 62 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Subtracting 57 from 62 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 19

Going ahead to step 5:
51 divided by 19 is 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 1032.0
Subtract 38 from 51 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 6:
The number 19 fits into 130 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 1032.6
Deduct 114 from 130 and we're left with 16.
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 7:
19 goes into 160 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1032.68
If we take 152 away from 160, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
19 goes into 80 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 1032.684
Subtracting 76 from 80 leaves us 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.

On to step 9:
When dividing 40 by 19, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 1032.6842
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.

Advancing to step 10:
19 goes into 20 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1032.68421
Deduct 19 from 20 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1032.68421
If we take 0 away from 10, we end up with 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:
If we divide 100 by 19, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1032.6842105
If we subtract 95 from 100, we 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.

Step 13:
50 divided by 19 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1032.68421052
If we take 38 away from 50, we end up 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.

The final outcome is 1032.68421052, with a leftover of 1.2e-08.
