We divide 503960 by 19
The aim is to understand the frequency of 19 in 503960.

Going ahead to step 1:
19 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 19

On to step 2:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 38 from 50 leaves us with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 19

Let's proceed to step 3:
19 can be fit into 123 6 times, resulting in a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 114 away from 123, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 19

On to step 4:
19 goes into 99 5 times with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
If we take 95 away from 99, we end up with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 19

On to step 5:
19 goes into 46 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2652.0
Deduct 38 from 46 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 19

Going ahead to step 6:
When dividing 80 by 19, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 26524.0
Subtracting 76 from 80 leaves us 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.

On to step 7:
If we divide 40 by 19, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 26524.2
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.

On to step 8:
20 divided by 19 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 26524.21
If we take 19 away from 20, we end up 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.

Let's proceed to step 9:
If we divide 10 by 19, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 26524.21
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 19, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 26524.2105
If we take 95 away from 100, we end up 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.

Moving on to step 11:
If we divide 50 by 19, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 26524.21052
Deduct 38 from 50 and we're left 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.

Advancing to step 12:
19 goes into 120 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 26524.210526
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.

Let's proceed to step 13:
When dividing 60 by 19, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 26524.2105263
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.

Moving on to step 14:
30 divided by 19 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 26524.21052631
Subtract 19 from 30 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 26524.21052631 with a remainder of 1.1e-08.
