Let's divide 503821 by 19
The aim is to understand the frequency of 19 in 503821.

Going ahead to step 1:
19 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 19

Step 2:
19 goes into 50 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 38 from 50, we get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 19

Moving on to step 3:
19 can be fit into 123 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 9 after subtracting 114 from 123.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 19

Going ahead to step 4:
When dividing 98 by 19, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
Subtract 95 from 98 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 19

On to step 5:
19 goes into 32 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 2651.0
Deduct 19 from 32 and we're left with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 19

Step 6:
When dividing 131 by 19, we get 6 with a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 26516.0
Deduct 114 from 131 and we're left 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.

Let's proceed to step 7:
170 divided by 19 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 26516.8
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.

On to step 8:
When dividing 180 by 19, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 26516.89
If we subtract 171 from 180, we get 9.
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 9:
19 goes into 90 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 26516.894
If we take 76 away from 90, we end up 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.

On to step 10:
140 divided by 19 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 26516.8947
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.

Moving on to step 11:
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: 26516.89473
Subtracting 57 from 70 leaves us 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 12:
19 goes into 130 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 26516.894736
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 26516.8947368
If we take 152 away from 160, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
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: 26516.89473684
Deduct 76 from 80 and we're left 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.

The quotient of the division is 26516.89473684, and the remainder is 4e-09.
