We look at the division of 31187 by 19 
We want to divide 31187 by 19.

Let's proceed to step 1:
3 divided by 19 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 19

Let's proceed to step 2:
If we divide 31 by 19, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 19 from 31 leaves us with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 19

Going ahead to step 3:
If we divide 121 by 19, we get 6 and a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 114 away from 121, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 19

Step 4:
The number 19 fits into 78 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Deduct 76 from 78 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 19

Step 5:
When dividing 27 by 19, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1641.0
The remainder is 8 after subtracting 19 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 6:
80 divided by 19 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 1641.4
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
19 goes into 40 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 1641.42
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
19 goes into 20 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1641.421
Deduct 19 from 20 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
19 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1641.421
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
19 goes into 100 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1641.42105
If we subtract 95 from 100, we 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.

Advancing to step 11:
If we divide 50 by 19, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 1641.421052
If we subtract 38 from 50, we get 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 12:
When dividing 120 by 19, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 1641.4210526
If we take 114 away from 120, we end up 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.

Step 13:
19 goes into 60 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1641.42105263
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.

After the division, we end up with 1641.42105263 and a remainder of 3e-09.
