133599 ÷ 3 
We're looking to find how many times 3 goes into 133599.

On to step 1:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Advancing to step 2:
3 goes into 13 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 12 from 13, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 3

Advancing to step 3:
13 divided by 3 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtract 12 from 13 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Step 4:
3 can be fit into 15 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 445.0
Deduct 15 from 15 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Going ahead to step 5:
If we divide 9 by 3, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 4453.0
Deduct 9 from 9 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

On to step 6:
3 can be fit into 9 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 44533.0
If we subtract 9 from 9, 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:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 44533.0
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.

Step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 44533.0
If we take 0 away from 0, we end up 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.

Our division results in 44533.0 with a remaining 0.0.
