20520705 ÷ 132 
Our goal is to divide 20520705 by 132.

Step 1:
132 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 132

Moving on to step 2:
20 divided by 132 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 132

Step 3:
205 divided by 132 is 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 132 from 205, we get 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 132

Moving on to step 4:
The number 132 fits into 732 5 times, leaving a remainder of 72.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 660 from 732, we get 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 132

Advancing to step 5:
132 can be fit into 720 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 155.0
If we take 660 away from 720, we end up with 60.
Fetch the next digit (7) from the dividend, attach it to 60 and continue: 607 / 132

On to step 6:
The number 132 fits into 607 4 times, leaving a remainder of 79.
Write down 4 as next digit of the result. 
Result so far: 1554.0
Subtract 528 from 607 to get 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 132

On to step 7:
790 divided by 132 is 5 with a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 15545.0
The remainder is 130 after subtracting 660 from 790.
Grab the next digit (5) from the dividend, add it to 130, then carry on: 1305 / 132

On to step 8:
132 can be fit into 1305 9 times, resulting in a remainder of 117.
The next digit of our result is 9. 
Result so far: 155459.0
Deduct 1188 from 1305 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 9:
1170 divided by 132 is 8 with a remainder of 114.
Use 8 as the next digit of our solution. 
Result so far: 155459.8
If we subtract 1056 from 1170, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 10:
132 can be fit into 1140 8 times, resulting in a remainder of 84.
The next digit of our result is 8. 
Result so far: 155459.88
Deduct 1056 from 1140 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 155459.88, with a leftover of 0.084.
