We divide 454586 by 19
The aim is to understand the frequency of 19 in 454586.

On to step 1:
19 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 19

On to step 2:
If we divide 45 by 19, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 38 from 45 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 19

Going ahead to step 3:
19 can be fit into 74 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 57 from 74 leaves us with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 19

Moving on to step 4:
The number 19 fits into 175 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 239.0
Deduct 171 from 175 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 19

Going ahead to step 5:
When dividing 48 by 19, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2392.0
If we take 38 away from 48, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 19

Going ahead to step 6:
When dividing 106 by 19, we get 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 23925.0
Deduct 95 from 106 and we're left 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.

Advancing to step 7:
If we divide 110 by 19, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 23925.5
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.

On to step 8:
The number 19 fits into 150 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 23925.57
Deduct 133 from 150 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.

Advancing to step 9:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 23925.578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
If we divide 180 by 19, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 23925.5789
Subtracting 171 from 180 leaves us 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.

Going ahead to step 11:
90 divided by 19 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 23925.57894
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.

Step 12:
When dividing 140 by 19, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 23925.578947
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.

Advancing to step 13:
If we divide 70 by 19, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 23925.5789473
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 14:
If we divide 130 by 19, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 23925.57894736
If we subtract 114 from 130, we 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.

The final outcome is 23925.57894736, with a leftover of 1.6e-08.
