845802 ÷ 19 
The aim is to understand the frequency of 19 in 845802.

Going ahead to step 1:
8 divided by 19 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 19

Advancing to step 2:
The number 19 fits into 84 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 76 from 84, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 19

Let's proceed to step 3:
When dividing 85 by 19, we get 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 76 from 85 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 19

Going ahead to step 4:
19 goes into 98 5 times with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 445.0
Subtract 95 from 98 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 19

Moving on to step 5:
19 goes into 30 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 4451.0
If we subtract 19 from 30, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 19

Step 6:
19 goes into 112 5 times with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 44515.0
Subtract 95 from 112 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.

Step 7:
The number 19 fits into 170 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 44515.8
Subtract 152 from 170 to get 18.
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 8:
180 divided by 19 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 44515.89
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:
When dividing 90 by 19, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 44515.894
The remainder is 14 after subtracting 76 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
140 divided by 19 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 44515.8947
If we subtract 133 from 140, we get 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 11:
19 goes into 70 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 44515.89473
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
If we divide 130 by 19, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 44515.894736
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.

Advancing to step 13:
19 goes into 160 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 44515.8947368
Subtracting 152 from 160 leaves us 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.

On to step 14:
19 can be fit into 80 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 44515.89473684
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.

The final result is 44515.89473684 with a remainder of 4e-09.
