We look at the division of 71637 by 19 
The aim is to understand the frequency of 19 in 71637.

Going ahead to step 1:
19 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 19

On to step 2:
The number 19 fits into 71 3 times, leaving a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 14 after subtracting 57 from 71.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 19

Step 3:
19 goes into 146 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtracting 133 from 146 leaves us with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 19

Moving on to step 4:
19 goes into 133 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 377.0
If we subtract 133 from 133, we get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 19

Advancing to step 5:
When dividing 7 by 19, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 3770.0
Subtracting 0 from 7 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 6:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3770.3
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.

On to step 7:
When dividing 130 by 19, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 3770.36
If we subtract 114 from 130, we get 16.
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:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 3770.368
Deduct 152 from 160 and we're left 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.

Step 9:
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: 3770.3684
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.

Advancing to step 10:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 3770.36842
Subtract 38 from 40 to 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 11:
20 divided by 19 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 3770.368421
If we subtract 19 from 20, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
If we divide 10 by 19, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3770.368421
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.

Step 13:
The number 19 fits into 100 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3770.36842105
Subtract 95 from 100 to 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.

The quotient of the division is 3770.36842105, and the remainder is 5e-09.
