We divide 643914 by 33
Let's see how many times 33 fits into 643914.

On to step 1:
33 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.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 33

Going ahead to step 2:
When dividing 64 by 33, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 33 from 64 and we're left with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 33

Let's proceed to step 3:
33 goes into 313 9 times with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 297 away from 313, we end up with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 33

On to step 4:
The number 33 fits into 169 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
If we take 165 away from 169, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 33

Advancing to step 5:
33 goes into 41 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1951.0
Subtract 33 from 41 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 33

Moving on to step 6:
The number 33 fits into 84 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 19512.0
Subtracting 66 from 84 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
If we divide 180 by 33, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 19512.5
Subtracting 165 from 180 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
150 divided by 33 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 19512.54
The remainder is 18 after subtracting 132 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
When dividing 180 by 33, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 19512.545
Subtract 165 from 180 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.

Going ahead to step 10:
The number 33 fits into 150 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 19512.5454
Subtract 132 from 150 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
33 can be fit into 180 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 19512.54545
Subtracting 165 from 180 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
33 goes into 150 4 times with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 19512.545454
If we subtract 132 from 150, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
33 can be fit into 180 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 19512.5454545
Subtract 165 from 180 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.

Going ahead to step 14:
The number 33 fits into 150 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 19512.54545454
If we subtract 132 from 150, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 19512.54545454 and a remainder of 1.8e-08.
