Let's divide 821458 by 19
The aim is to understand the frequency of 19 in 821458.

On to step 1:
If we divide 8 by 19, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 19

Step 2:
The number 19 fits into 82 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 76 from 82 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 19

On to step 3:
61 divided by 19 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 57 away from 61, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 19

Advancing to step 4:
If we divide 44 by 19, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 432.0
If we take 38 away from 44, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 19

Moving on to step 5:
When dividing 65 by 19, we get 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 4323.0
If we take 57 away from 65, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 19

On to step 6:
88 divided by 19 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 43234.0
If we take 76 away from 88, 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.

Let's proceed to step 7:
120 divided by 19 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 43234.6
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.

Advancing to step 8:
19 goes into 60 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 43234.63
Deduct 57 from 60 and we're left 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.

Advancing to step 9:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 43234.631
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.

Moving on to step 10:
19 goes into 110 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 43234.6315
If we take 95 away from 110, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving 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: 43234.63157
Subtract 133 from 150 to 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.

On to step 12:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 43234.631578
Subtracting 152 from 170 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 43234.6315789
If we take 171 away from 180, we end up 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.

Moving on to step 14:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 43234.63157894
Deduct 76 from 90 and we're left 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.

Our division results in 43234.63157894 with a remaining 1.4e-08.
