644535 divided by 33 
Let's see how many times 33 fits into 644535.

Advancing to step 1:
33 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 33

Going ahead to step 2:
33 can be fit into 64 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 31 after subtracting 33 from 64.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 33

Let's proceed to step 3:
33 can be fit into 314 9 times, resulting in a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 297 away from 314, we end up with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 33

Moving on to step 4:
When dividing 175 by 33, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 195.0
Subtract 165 from 175 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 33

Let's proceed to step 5:
If we divide 103 by 33, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1953.0
Subtract 99 from 103 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 33

Going ahead to step 6:
When dividing 45 by 33, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 19531.0
Deduct 33 from 45 and we're left 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 7:
If we divide 120 by 33, we get 3 and a remainder of 21.
The next digit of our result is 3. 
Result so far: 19531.3
The remainder is 21 after subtracting 99 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 8:
When dividing 210 by 33, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 19531.36
If we take 198 away from 210, we end up 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.

Let's proceed to step 9:
When dividing 120 by 33, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 19531.363
The remainder is 21 after subtracting 99 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
The number 33 fits into 210 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 19531.3636
If we take 198 away from 210, we end up 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.

On to step 11:
33 can be fit into 120 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 19531.36363
If we subtract 99 from 120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
The number 33 fits into 210 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 19531.363636
If we take 198 away from 210, we end up 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.

Let's proceed to step 13:
If we divide 120 by 33, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 19531.3636363
The remainder is 21 after subtracting 99 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
210 divided by 33 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 19531.36363636
If we subtract 198 from 210, we 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.

The final result is 19531.36363636 with a remainder of 1.2e-08.
