734800 divided by 19 
The aim is to understand the frequency of 19 in 734800.

Let's proceed to step 1:
7 divided by 19 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 19

Advancing to step 2:
19 can be fit into 73 3 times, resulting in a remainder of 16.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 57 from 73 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 19

Step 3:
When dividing 164 by 19, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 152 away from 164, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 19

On to step 4:
When dividing 128 by 19, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 386.0
If we subtract 114 from 128, we get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 19

Advancing to step 5:
When dividing 140 by 19, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 3867.0
If we subtract 133 from 140, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 19

Step 6:
19 goes into 70 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 38673.0
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.

Going ahead to step 7:
When dividing 130 by 19, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 38673.6
The remainder is 16 after subtracting 114 from 130.
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 8:
If we divide 160 by 19, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 38673.68
Subtract 152 from 160 to get 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 9:
When dividing 80 by 19, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 38673.684
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.

Going ahead to step 10:
The number 19 fits into 40 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 38673.6842
Deduct 38 from 40 and we're left 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.

Let's proceed to step 11:
19 can be fit into 20 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 38673.68421
The remainder is 1 after subtracting 19 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
10 divided by 19 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 38673.68421
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
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: 38673.6842105
Deduct 95 from 100 and we're left with 5.
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 14:
50 divided by 19 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 38673.68421052
Subtracting 38 from 50 leaves us 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.

Our division results in 38673.68421052 with a remaining 1.2e-08.
