Let's divide 843357 by 19
The aim is to understand the frequency of 19 in 843357.

On to step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 19

Going ahead to step 2:
19 goes into 84 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 76 from 84, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 19

Going ahead to step 3:
83 divided by 19 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 76 away from 83, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 19

Let's proceed to step 4:
If we divide 73 by 19, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 443.0
Deduct 57 from 73 and we're left with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 19

Moving on to step 5:
The number 19 fits into 165 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 4438.0
Subtract 152 from 165 to get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 19

On to step 6:
If we divide 137 by 19, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 44387.0
The remainder is 4 after subtracting 133 from 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
40 divided by 19 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 44387.2
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.

Moving on to step 8:
If we divide 20 by 19, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 44387.21
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 44387.21
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
19 goes into 100 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 44387.2105
If we take 95 away from 100, 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.

Moving on to step 11:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 44387.21052
The remainder is 12 after subtracting 38 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 44387.210526
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 44387.2105263
Deduct 57 from 60 and we're left with 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 14:
30 divided by 19 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 44387.21052631
If we subtract 19 from 30, we 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.

Our division results in 44387.21052631 with a remaining 1.1e-08.
