901916 ÷ 19 
The aim is to understand the frequency of 19 in 901916.

Moving on to step 1:
The number 19 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 19

Advancing to step 2:
When dividing 90 by 19, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 76 from 90, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 19

Moving on to step 3:
If we divide 141 by 19, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 47.0
If we subtract 133 from 141, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 19

Going ahead to step 4:
The number 19 fits into 89 4 times, leaving a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
If we subtract 76 from 89, we get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 19

Moving on to step 5:
The number 19 fits into 131 6 times, leaving a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 4746.0
If we take 114 away from 131, we end up with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 19

On to step 6:
The number 19 fits into 176 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 47469.0
If we take 171 away from 176, 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.

On to step 7:
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: 47469.2
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.

Moving on to step 8:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 47469.26
Subtracting 114 from 120 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
When dividing 60 by 19, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 47469.263
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 10:
19 can be fit into 30 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 47469.2631
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.

On to step 11:
When dividing 110 by 19, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 47469.26315
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 12:
When dividing 150 by 19, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 47469.263157
Subtract 133 from 150 to 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 13:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 47469.2631578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 47469.26315789
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 47469.26315789, and the remainder is 9e-09.
