We divide 485405 by 19
The aim is to understand the frequency of 19 in 485405.

Going ahead to step 1:
The number 19 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 19

Advancing to step 2:
19 can be fit into 48 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 38 from 48 and we're left with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 19

Moving on to step 3:
19 goes into 105 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 95 from 105, we get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 19

Going ahead to step 4:
19 goes into 104 5 times with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 255.0
Subtracting 95 from 104 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 19

Moving on to step 5:
19 can be fit into 90 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 2554.0
If we take 76 away from 90, we end up with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 19

Let's proceed to step 6:
When dividing 145 by 19, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 25547.0
The remainder is 12 after subtracting 133 from 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
120 divided by 19 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 25547.6
Subtracting 114 from 120 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 19 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 25547.63
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 25547.631
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
If we divide 110 by 19, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 25547.6315
The remainder is 15 after subtracting 95 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
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: 25547.63157
If we subtract 133 from 150, we 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.

On to step 12:
If we divide 170 by 19, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 25547.631578
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.

Going ahead to step 13:
19 can be fit into 180 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 25547.6315789
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.

Moving on to step 14:
19 goes into 90 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 25547.63157894
Deduct 76 from 90 and we're left 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.

After the division, we end up with 25547.63157894 and a remainder of 1.4e-08.
