We're dividing 21593072 by 19 
The aim is to understand the frequency of 19 in 21593072.

Going ahead to step 1:
If we divide 2 by 19, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 19

Let's proceed to step 2:
19 goes into 21 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 19 from 21 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 19

Advancing to step 3:
When dividing 25 by 19, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 19 from 25 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 19

Moving on to step 4:
19 goes into 69 3 times with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Subtracting 57 from 69 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 19

On to step 5:
19 goes into 123 6 times with a remainder of 9.
The next digit of our result is 6. 
Result so far: 1136.0
Deduct 114 from 123 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 19

Let's proceed to step 6:
19 goes into 90 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 11364.0
Deduct 76 from 90 and we're left with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 19

Going ahead to step 7:
147 divided by 19 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 113647.0
Deduct 133 from 147 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 19

On to step 8:
If we divide 142 by 19, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 1136477.0
The remainder is 9 after subtracting 133 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
When dividing 90 by 19, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 1136477.4
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.

Let's proceed to step 10:
When dividing 140 by 19, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1136477.47
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.

Step 11:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 1136477.473
If we subtract 57 from 70, we 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.

Moving on to step 12:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 1136477.4736
Subtracting 114 from 130 leaves us 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.

Moving on to step 13:
When dividing 160 by 19, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 1136477.47368
Subtracting 152 from 160 leaves us 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.

On to step 14:
If we divide 80 by 19, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 1136477.473684
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.

Moving on to step 15:
19 goes into 40 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1136477.4736842
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 16:
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: 1136477.47368421
Subtract 19 from 20 to 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.

In conclusion, the division gives 1136477.47368421 with a balance of 1e-09.
