We divide 203890 by 19
We're looking to find how many times 19 goes into 203890.

On to step 1:
The number 19 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 19

Step 2:
The number 19 fits into 20 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 19 from 20, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 19

Let's proceed to step 3:
If we divide 13 by 19, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 19

Going ahead to step 4:
If we divide 138 by 19, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtract 133 from 138 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 19

Step 5:
When dividing 59 by 19, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1073.0
The remainder is 2 after subtracting 57 from 59.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 19

On to step 6:
20 divided by 19 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 10731.0
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 19, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10731.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 19 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 10731.05
Subtract 95 from 100 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
19 can be fit into 50 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 10731.052
Deduct 38 from 50 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
19 goes into 120 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 10731.0526
If we subtract 114 from 120, we 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.

Step 11:
19 can be fit into 60 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 10731.05263
If we subtract 57 from 60, we 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.

On to step 12:
30 divided by 19 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 10731.052631
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.

Let's proceed to step 13:
19 goes into 110 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 10731.0526315
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 14:
19 goes into 150 7 times with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 10731.05263157
Subtract 133 from 150 to 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.

Our division results in 10731.05263157 with a remaining 1.7e-08.
