We look at the division of 640435 by 19 
Our goal is to divide 640435 by 19.

Advancing to step 1:
If we divide 6 by 19, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 19

Going ahead to step 2:
19 can be fit into 64 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 57 from 64 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 19

On to step 3:
When dividing 70 by 19, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 57 from 70, we get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 19

Let's proceed to step 4:
When dividing 134 by 19, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 337.0
The remainder is 1 after subtracting 133 from 134.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 19

Let's proceed to step 5:
The number 19 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 3370.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 19

Moving on to step 6:
The number 19 fits into 135 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 33707.0
The remainder is 2 after subtracting 133 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
When dividing 20 by 19, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 33707.1
Subtracting 19 from 20 leaves us 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.

Going ahead to step 8:
19 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 33707.1
If we take 0 away from 10, we end up 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.

Step 9:
The number 19 fits into 100 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 33707.105
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.

On to step 10:
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: 33707.1052
Subtracting 38 from 50 leaves us 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.

Going ahead to step 11:
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: 33707.10526
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 12:
19 can be fit into 60 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 33707.105263
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.

Going ahead to step 13:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 33707.1052631
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
When dividing 110 by 19, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 33707.10526315
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 33707.10526315 and a remainder of 1.5e-08.
