Let's divide 387138 by 19
Our goal is to divide 387138 by 19.

Moving on to step 1:
19 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 19

Moving 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
Subtract 38 from 38 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 19

Step 3:
19 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 19

Let's proceed to step 4:
19 goes into 71 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
If we take 57 away from 71, we end up with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 19

Advancing to step 5:
If we divide 143 by 19, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 2037.0
Subtracting 133 from 143 leaves us with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 19

Let's proceed to step 6:
108 divided by 19 is 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 20375.0
Subtracting 95 from 108 leaves us 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.

Going ahead to step 7:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 20375.6
Subtracting 114 from 130 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
160 divided by 19 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 20375.68
If we subtract 152 from 160, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 19, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 20375.684
Subtracting 76 from 80 leaves us with 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 10:
19 can be fit into 40 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 20375.6842
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
If we divide 20 by 19, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 20375.68421
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 12:
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: 20375.68421
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
100 divided by 19 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 20375.6842105
The remainder is 5 after subtracting 95 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
When dividing 50 by 19, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 20375.68421052
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.

The final result is 20375.68421052 with a remainder of 1.2e-08.
