141021 divided by 19 
The aim is to understand the frequency of 19 in 141021.

Let's proceed to step 1:
19 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 19

Going ahead to step 2:
14 divided by 19 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 19

Going ahead to step 3:
If we divide 141 by 19, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 133 from 141 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 19

On to step 4:
When dividing 80 by 19, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtracting 76 from 80 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 19

Let's proceed to step 5:
The number 19 fits into 42 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 742.0
If we take 38 away from 42, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 19

On to step 6:
The number 19 fits into 41 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 7422.0
Deduct 38 from 41 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.

Moving on to step 7:
If we divide 30 by 19, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 7422.1
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
19 can be fit into 110 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 7422.15
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.

Advancing to step 9:
19 can be fit into 150 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 7422.157
Subtracting 133 from 150 leaves us with 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 10:
19 goes into 170 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 7422.1578
If we take 152 away from 170, we end up 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 11:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 7422.15789
Subtracting 171 from 180 leaves us 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.

Let's proceed to step 12:
When dividing 90 by 19, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 7422.157894
The remainder is 14 after subtracting 76 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
If we divide 140 by 19, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 7422.1578947
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
If we divide 70 by 19, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 7422.15789473
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.

The final result is 7422.15789473 with a remainder of 1.3e-08.
