Let's divide 640180 by 19
We want to divide 640180 by 19.

Going ahead to step 1:
6 divided by 19 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 19

Let's proceed to step 2:
64 divided by 19 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 57 from 64, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 19

Step 3:
19 goes into 70 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 57 away from 70, we end up with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 19

Moving on to step 4:
131 divided by 19 is 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 336.0
The remainder is 17 after subtracting 114 from 131.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 19

Moving on to step 5:
The number 19 fits into 178 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 3369.0
Subtracting 171 from 178 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 19

Moving on to step 6:
When dividing 70 by 19, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 33693.0
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
If we divide 130 by 19, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 33693.6
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 next digit of our result is 8. 
Result so far: 33693.68
Deduct 152 from 160 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 19 fits into 80 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 33693.684
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 33693.6842
If we subtract 38 from 40, we get 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 11:
19 goes into 20 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 33693.68421
If we take 19 away from 20, we end up 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 12:
10 divided by 19 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 33693.68421
Deduct 0 from 10 and we're left 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.

Moving on to step 13:
When dividing 100 by 19, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 33693.6842105
Deduct 95 from 100 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
50 divided by 19 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 33693.68421052
Subtract 38 from 50 to 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 33693.68421052 with a remainder of 1.2e-08.
