We're dividing 487510 by 19 
The aim is to understand the frequency of 19 in 487510.

Let's proceed to step 1:
If we divide 4 by 19, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 19

On to step 2:
19 can be fit into 48 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 38 from 48, we get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 19

Moving on to step 3:
The number 19 fits into 107 5 times, leaving a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 95 from 107 leaves us with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 19

Step 4:
If we divide 125 by 19, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 256.0
If we take 114 away from 125, we end up with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 19

Advancing to step 5:
19 can be fit into 111 5 times, resulting in a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 2565.0
Subtract 95 from 111 to get 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 19

Going ahead to step 6:
160 divided by 19 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 25658.0
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.

Advancing to step 7:
80 divided by 19 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 25658.4
If we subtract 76 from 80, we get 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 8:
If we divide 40 by 19, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 25658.42
If we subtract 38 from 40, we 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.

On to step 9:
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: 25658.421
Subtracting 19 from 20 leaves us 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:
When dividing 10 by 19, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 25658.421
Deduct 0 from 10 and we're left 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.

Let's proceed to step 11:
19 goes into 100 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 25658.42105
Subtracting 95 from 100 leaves us 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.

On to step 12:
50 divided by 19 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 25658.421052
If we take 38 away from 50, we end up 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.

Step 13:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 25658.4210526
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
19 goes into 60 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 25658.42105263
Subtracting 57 from 60 leaves us 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 25658.42105263, with a leftover of 3e-09.
