Let's divide 72880 by 19
The aim is to understand the frequency of 19 in 72880.

Step 1:
19 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 19

Advancing to step 2:
The number 19 fits into 72 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 57 away from 72, we end up with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 19

On to step 3:
If we divide 158 by 19, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we subtract 152 from 158, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 19

On to step 4:
19 goes into 68 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 383.0
The remainder is 11 after subtracting 57 from 68.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 19

Step 5:
The number 19 fits into 110 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3835.0
Subtracting 95 from 110 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 6:
When dividing 150 by 19, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 3835.7
Deduct 133 from 150 and we're left with 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 7:
19 goes into 170 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 3835.78
Subtracting 152 from 170 leaves us 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 8:
180 divided by 19 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 3835.789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
If we divide 90 by 19, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 3835.7894
Subtract 76 from 90 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 3835.78947
Subtracting 133 from 140 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.

Moving on to step 11:
19 can be fit into 70 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3835.789473
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 12:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 3835.7894736
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
160 divided by 19 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 3835.78947368
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 3835.78947368, and the remainder is 8e-09.
