123083 ÷ 19 
The aim is to understand the frequency of 19 in 123083.

Let's proceed to step 1:
1 divided by 19 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 19

Moving on to step 2:
12 divided by 19 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 19

Advancing to step 3:
The number 19 fits into 123 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 114 away from 123, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 19

Advancing to step 4:
19 goes into 90 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we subtract 76 from 90, we get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 19

On to step 5:
The number 19 fits into 148 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 647.0
Deduct 133 from 148 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 19

Let's proceed to step 6:
When dividing 153 by 19, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 6478.0
If we subtract 152 from 153, we 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 7:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 6478.0
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.

On to step 8:
If we divide 100 by 19, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6478.05
Deduct 95 from 100 and we're left 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.

Step 9:
When dividing 50 by 19, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 6478.052
If we subtract 38 from 50, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
120 divided by 19 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 6478.0526
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
When dividing 60 by 19, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 6478.05263
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.

Moving on to step 12:
19 goes into 30 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 6478.052631
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
19 goes into 110 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 6478.0526315
Deduct 95 from 110 and we're left 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.

Going ahead to step 14:
When dividing 150 by 19, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 6478.05263157
Subtract 133 from 150 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.

After the division, we end up with 6478.05263157 and a remainder of 1.7e-08.
