We're dividing 132621 by 4 
Let's see how many times 4 fits into 132621.

Moving on to step 1:
The number 4 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 4

Going ahead to step 2:
The number 4 fits into 13 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 12 from 13 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

Advancing to step 3:
If we divide 12 by 4, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Deduct 12 from 12 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 4

On to step 4:
The number 4 fits into 6 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 331.0
The remainder is 2 after subtracting 4 from 6.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 4

Going ahead to step 5:
If we divide 22 by 4, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 3315.0
The remainder is 2 after subtracting 20 from 22.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 4

Moving on to step 6:
4 can be fit into 21 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 33155.0
Deduct 20 from 21 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 33155.2
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 4, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 33155.25
Subtract 20 from 20 to 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.

Let's proceed to step 9:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33155.25
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.

Moving on to step 10:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33155.25
If we subtract 0 from 0, 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.

The final result is 33155.25 with a remainder of 0.0.
