29193421 ÷ 19 
The aim is to understand the frequency of 19 in 29193421.

On to step 1:
19 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 19

On to step 2:
If we divide 29 by 19, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 19 away from 29, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 19

Going ahead to step 3:
When dividing 101 by 19, we get 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 6 after subtracting 95 from 101.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 19

Step 4:
19 can be fit into 69 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
If we subtract 57 from 69, we get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 19

Let's proceed to step 5:
19 can be fit into 123 6 times, resulting in a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 1536.0
Deduct 114 from 123 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 19

Moving on to step 6:
If we divide 94 by 19, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 15364.0
The remainder is 18 after subtracting 76 from 94.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 19

Let's proceed to step 7:
182 divided by 19 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 153649.0
If we take 171 away from 182, we end up with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 19

Advancing to step 8:
19 goes into 111 5 times with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 1536495.0
Subtract 95 from 111 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.

On to step 9:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1536495.8
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
If we divide 80 by 19, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 1536495.84
If we take 76 away from 80, we end up 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.

Step 11:
The number 19 fits into 40 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 1536495.842
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.

Let's proceed to step 12:
19 goes into 20 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1536495.8421
If we take 19 away from 20, we end up 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.

Let's proceed to step 13:
If we divide 10 by 19, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1536495.8421
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.

Moving on to step 14:
If we divide 100 by 19, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1536495.842105
The remainder is 5 after subtracting 95 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 15:
19 goes into 50 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 1536495.8421052
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.

Going ahead to step 16:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 1536495.84210526
Subtracting 114 from 120 leaves us with 6.
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 1536495.84210526 with a remaining 6e-09.
