We divide 181632 by 19
The aim is to understand the frequency of 19 in 181632.

Going ahead to step 1:
When dividing 1 by 19, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 19

On to step 2:
19 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 19

Going ahead to step 3:
If we divide 181 by 19, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 10 after subtracting 171 from 181.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 19

Step 4:
The number 19 fits into 106 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 95.0
The remainder is 11 after subtracting 95 from 106.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 19

On to step 5:
If we divide 113 by 19, we get 5 and a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 955.0
The remainder is 18 after subtracting 95 from 113.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 19

Step 6:
The number 19 fits into 182 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 9559.0
Deduct 171 from 182 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.

Moving on to step 7:
The number 19 fits into 110 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 9559.5
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.

Advancing to step 8:
When dividing 150 by 19, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 9559.57
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 goes into 170 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 9559.578
Subtracting 152 from 170 leaves us 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.

Moving on to step 10:
180 divided by 19 is 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 9559.5789
Deduct 171 from 180 and we're left 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.

Moving on to step 11:
The number 19 fits into 90 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 9559.57894
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.

Let's proceed to step 12:
19 goes into 140 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 9559.578947
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.

On to step 13:
70 divided by 19 is 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 9559.5789473
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:
The number 19 fits into 130 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 9559.57894736
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.

The final outcome is 9559.57894736, with a leftover of 1.6e-08.
