782142 ÷ 19 
The aim is to understand the frequency of 19 in 782142.

Going ahead to step 1:
The number 19 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 19

Let's proceed to step 2:
78 divided by 19 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 76 from 78 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 19

Moving on to step 3:
The number 19 fits into 22 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtracting 19 from 22 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 19

Moving on to step 4:
19 goes into 31 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 411.0
If we take 19 away from 31, we end up with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 19

Step 5:
19 can be fit into 124 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 4116.0
Deduct 114 from 124 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 19

On to step 6:
If we divide 102 by 19, we get 5 and a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 41165.0
Deduct 95 from 102 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.

Let's proceed to step 7:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 41165.3
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
19 goes into 130 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 41165.36
The remainder is 16 after subtracting 114 from 130.
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 9:
19 can be fit into 160 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 41165.368
The remainder is 8 after subtracting 152 from 160.
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 10:
If we divide 80 by 19, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 41165.3684
Subtracting 76 from 80 leaves us with 4.
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 11:
If we divide 40 by 19, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 41165.36842
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.

Moving on to step 12:
If we divide 20 by 19, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 41165.368421
The remainder is 1 after subtracting 19 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
When dividing 10 by 19, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 41165.368421
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.

On to step 14:
19 goes into 100 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 41165.36842105
The remainder is 5 after subtracting 95 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 41165.36842105, with a leftover of 5e-09.
