557846 ÷ 19 
The aim is to understand the frequency of 19 in 557846.

Advancing to step 1:
5 divided by 19 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 19

On to step 2:
19 goes into 55 2 times with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 38 from 55, we get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 19

Advancing to step 3:
The number 19 fits into 177 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtracting 171 from 177 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 19

On to step 4:
If we divide 68 by 19, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 293.0
The remainder is 11 after subtracting 57 from 68.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 19

Let's proceed to step 5:
19 can be fit into 114 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 2936.0
If we subtract 114 from 114, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 19

Moving on to step 6:
The number 19 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 29360.0
Subtracting 0 from 6 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.

Moving on to step 7:
60 divided by 19 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 29360.3
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
19 goes into 30 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 29360.31
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.

Going ahead to step 9:
110 divided by 19 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 29360.315
If we take 95 away from 110, we end up 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.

Advancing to step 10:
If we divide 150 by 19, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 29360.3157
Subtracting 133 from 150 leaves us with 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 11:
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: 29360.31578
Deduct 152 from 170 and we're left with 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 12:
19 goes into 180 9 times with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 29360.315789
If we take 171 away from 180, we end up 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.

Step 13:
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: 29360.3157894
Subtracting 76 from 90 leaves us 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.

Let's proceed to step 14:
140 divided by 19 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 29360.31578947
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.

The final outcome is 29360.31578947, with a leftover of 7e-09.
