We divide 831625 by 19
The aim is to understand the frequency of 19 in 831625.

Let's proceed to step 1:
19 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 19

Step 2:
If we divide 83 by 19, we get 4 and a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 76 from 83, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 19

On to step 3:
If we divide 71 by 19, we get 3 and a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 57 from 71 to get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 19

Moving on to step 4:
19 can be fit into 146 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 437.0
Subtract 133 from 146 to get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 19

Moving on to step 5:
The number 19 fits into 132 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 4376.0
The remainder is 18 after subtracting 114 from 132.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 19

Advancing to step 6:
19 can be fit into 185 9 times, resulting in a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 43769.0
Deduct 171 from 185 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
19 goes into 140 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 43769.7
Deduct 133 from 140 and we're left 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.

Advancing to step 8:
The number 19 fits into 70 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 43769.73
If we take 57 away from 70, we end up 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.

Step 9:
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: 43769.736
Subtract 114 from 130 to 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.

Going ahead to step 10:
If we divide 160 by 19, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 43769.7368
Deduct 152 from 160 and we're left 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 11:
19 goes into 80 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 43769.73684
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.

Going ahead to step 12:
When dividing 40 by 19, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 43769.736842
Deduct 38 from 40 and we're left 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 13:
When dividing 20 by 19, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 43769.7368421
Subtracting 19 from 20 leaves us 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.

Going ahead to step 14:
The number 19 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 43769.7368421
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 43769.7368421, with a leftover of 1e-08.
