Let's divide 663004 by 19
The aim is to understand the frequency of 19 in 663004.

Moving on to step 1:
19 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 19

Step 2:
19 can be fit into 66 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 9 after subtracting 57 from 66.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 19

Moving on to step 3:
If we divide 93 by 19, we get 4 and a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
The remainder is 17 after subtracting 76 from 93.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 19

Let's proceed to step 4:
170 divided by 19 is 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 348.0
Subtracting 152 from 170 leaves us with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 19

Going ahead to step 5:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 3489.0
Subtracting 171 from 180 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 19

Step 6:
If we divide 94 by 19, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 34894.0
The remainder is 18 after subtracting 76 from 94.
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 7:
19 goes into 180 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 34894.9
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
19 goes into 90 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 34894.94
The remainder is 14 after subtracting 76 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 34894.947
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.

Moving on to step 10:
70 divided by 19 is 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 34894.9473
Deduct 57 from 70 and we're left 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.

Advancing to step 11:
When dividing 130 by 19, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 34894.94736
Subtracting 114 from 130 leaves us with 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 12:
19 can be fit into 160 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 34894.947368
If we subtract 152 from 160, we get 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 13:
If we divide 80 by 19, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 34894.9473684
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
If we divide 40 by 19, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 34894.94736842
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 34894.94736842 and a remainder of 2e-09.
