382121 divided by 19 
We want to figure out the number of times 382121 can be divided by 19.

On to step 1:
If we divide 3 by 19, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 19

On to step 2:
The number 19 fits into 38 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 38 away from 38, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 19

Moving on to step 3:
19 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 19

Advancing to step 4:
21 divided by 19 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 201.0
If we take 19 away from 21, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 19

On to step 5:
When dividing 22 by 19, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 2011.0
If we subtract 19 from 22, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 19

Moving on to step 6:
The number 19 fits into 31 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 20111.0
The remainder is 12 after subtracting 19 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
19 goes into 120 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 20111.6
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 20111.63
If we take 57 away from 60, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
30 divided by 19 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 20111.631
Subtract 19 from 30 to get 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 10:
If we divide 110 by 19, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 20111.6315
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.

Let's proceed to step 11:
19 goes into 150 7 times with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 20111.63157
If we take 133 away from 150, we end up 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 12:
19 goes into 170 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 20111.631578
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.

Advancing to step 13:
When dividing 180 by 19, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 20111.6315789
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.

On to step 14:
The number 19 fits into 90 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 20111.63157894
Subtracting 76 from 90 leaves us 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.

The final outcome is 20111.63157894, with a leftover of 1.4e-08.
