Let's divide 545612 by 19
The aim is to understand the frequency of 19 in 545612.

On to step 1:
The number 19 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 19

Step 2:
The number 19 fits into 54 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 38 from 54 leaves us with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 19

Step 3:
165 divided by 19 is 8 with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 152 from 165 and we're left with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 19

Moving on to step 4:
When dividing 136 by 19, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
If we subtract 133 from 136, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 19

Let's proceed to step 5:
When dividing 31 by 19, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 2871.0
The remainder is 12 after subtracting 19 from 31.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 19

Let's proceed to step 6:
If we divide 122 by 19, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 28716.0
If we take 114 away from 122, we end up 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.

Moving on to step 7:
If we divide 80 by 19, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 28716.4
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
If we divide 40 by 19, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 28716.42
Subtracting 38 from 40 leaves us 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.

Step 9:
When dividing 20 by 19, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 28716.421
Deduct 19 from 20 and we're left 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.

On to step 10:
19 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 28716.421
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.

Advancing to step 11:
The number 19 fits into 100 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 28716.42105
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.

Going ahead to step 12:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 28716.421052
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.

Moving on to step 13:
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: 28716.4210526
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
60 divided by 19 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 28716.42105263
If we take 57 away from 60, we end up 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.

The final outcome is 28716.42105263, with a leftover of 3e-09.
