Let's divide 640737 by 19
Our goal is to divide 640737 by 19.

Moving on to step 1:
19 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 19

Advancing to step 2:
When dividing 64 by 19, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 57 from 64 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 19

Moving on to step 3:
70 divided by 19 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 57 from 70 and we're left with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 19

Moving on to step 4:
137 divided by 19 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 337.0
Subtracting 133 from 137 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 19

Let's proceed to step 5:
When dividing 43 by 19, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 3372.0
Subtract 38 from 43 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 19

Let's proceed to step 6:
19 goes into 57 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33723.0
If we subtract 57 from 57, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 19 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33723.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 19, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 33723.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 33723.0, with a leftover of 0.0.
