Let's divide 51381 by 19
The aim is to understand the frequency of 19 in 51381.

Let's proceed to step 1:
19 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 19

Going ahead to step 2:
When dividing 51 by 19, we get 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 38 from 51 to get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 19

Advancing to step 3:
The number 19 fits into 133 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 133 from 133, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 19

On to step 4:
19 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 270.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 19

Moving on to step 5:
When dividing 81 by 19, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 2704.0
If we subtract 76 from 81, we get 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 6:
When dividing 50 by 19, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2704.2
Subtract 38 from 50 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
19 goes into 120 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 2704.26
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.

Advancing to step 8:
If we divide 60 by 19, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2704.263
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
The number 19 fits into 30 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 2704.2631
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.

Let's proceed to step 10:
19 goes into 110 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2704.26315
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
The number 19 fits into 150 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 2704.263157
If we subtract 133 from 150, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 2704.2631578
If we take 152 away from 170, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 2704.26315789
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 2704.26315789 with a remaining 9e-09.
