We're dividing 640802 by 19 
Our goal is to divide 640802 by 19.

Going ahead to step 1:
The number 19 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 19

Advancing to step 2:
The number 19 fits into 64 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 7 after subtracting 57 from 64.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 19

On to step 3:
When dividing 70 by 19, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 57 from 70, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 19

Moving on to step 4:
19 goes into 138 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 337.0
Subtract 133 from 138 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 19

On to step 5:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3372.0
Subtracting 38 from 50 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 19

Going ahead to step 6:
The number 19 fits into 122 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 33726.0
If we subtract 114 from 122, 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.

Step 7:
19 can be fit into 80 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 33726.4
If we take 76 away from 80, we end up 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 8:
19 goes into 40 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 33726.42
Subtract 38 from 40 to 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.

Going ahead to step 9:
If we divide 20 by 19, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 33726.421
If we subtract 19 from 20, we 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.

Let's proceed to step 10:
If we divide 10 by 19, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 33726.421
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.

Let's proceed to step 11:
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: 33726.42105
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.

Advancing to step 12:
50 divided by 19 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 33726.421052
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.

On to step 13:
When dividing 120 by 19, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 33726.4210526
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.

Going ahead to step 14:
If we divide 60 by 19, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 33726.42105263
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.

The final outcome is 33726.42105263, with a leftover of 3e-09.
