305852 divided by 19 
The aim is to understand the frequency of 19 in 305852.

Step 1:
When dividing 3 by 19, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 19

Moving on to step 2:
If we divide 30 by 19, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 19 from 30 to get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 19

Moving on to step 3:
The number 19 fits into 115 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 114 from 115 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 19

Advancing to step 4:
18 divided by 19 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 160.0
Subtract 0 from 18 to get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 19

Advancing to step 5:
19 goes into 185 9 times with a remainder of 14.
The next digit of our result is 9. 
Result so far: 1609.0
If we take 171 away from 185, we end up with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 19

Moving on to step 6:
142 divided by 19 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 16097.0
Subtracting 133 from 142 leaves us with 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 7:
19 goes into 90 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 16097.4
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.

Moving on to step 8:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 16097.47
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.

On to step 9:
If we divide 70 by 19, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 16097.473
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.

Advancing to step 10:
When dividing 130 by 19, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 16097.4736
Subtracting 114 from 130 leaves us with 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 11:
When dividing 160 by 19, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 16097.47368
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.

Step 12:
When dividing 80 by 19, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 16097.473684
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
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: 16097.4736842
If we take 38 away from 40, we end up with 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 14:
When dividing 20 by 19, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 16097.47368421
If we take 19 away from 20, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 16097.47368421, and the remainder is 1e-09.
