640963 divided by 27 
We want to figure out the number of times 640963 can be divided by 27.

Going ahead to step 1:
27 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 27

Let's proceed to step 2:
If we divide 64 by 27, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 54 from 64 to get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 27

Moving on to step 3:
100 divided by 27 is 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 81 from 100 leaves us with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 27

Moving on to step 4:
199 divided by 27 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 237.0
If we take 189 away from 199, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 27

Advancing to step 5:
If we divide 106 by 27, we get 3 and a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 2373.0
The remainder is 25 after subtracting 81 from 106.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 27

Let's proceed to step 6:
27 goes into 253 9 times with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 23739.0
Subtracting 243 from 253 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.

Advancing to step 7:
When dividing 100 by 27, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 23739.3
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
27 can be fit into 190 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 23739.37
Subtract 189 from 190 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.

Let's proceed to step 9:
The number 27 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 23739.37
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.

Going ahead to step 10:
27 can be fit into 100 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 23739.3703
Subtract 81 from 100 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
27 can be fit into 190 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 23739.37037
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
27 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 23739.37037
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:
If we divide 100 by 27, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 23739.3703703
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
The number 27 fits into 190 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 23739.37037037
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 23739.37037037 and a remainder of 1e-09.
