We look at the division of 91466 by 19 
The aim is to understand the frequency of 19 in 91466.

Going ahead to step 1:
The number 19 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 19

On to step 2:
If we divide 91 by 19, we get 4 and a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 76 from 91 leaves us with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 19

Step 3:
19 can be fit into 154 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtract 152 from 154 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 19

Step 4:
26 divided by 19 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 481.0
Subtracting 19 from 26 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 19

Moving on to step 5:
If we divide 76 by 19, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4814.0
If we take 76 away from 76, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 6:
The number 19 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4814.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
19 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 4814.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4814.0, and the remainder is 0.0.
