We divide 105531 by 20
We're looking to find how many times 20 goes into 105531.

Moving on to step 1:
20 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 20

Step 2:
20 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 20

Advancing to step 3:
20 can be fit into 105 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 5 after subtracting 100 from 105.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 20

Let's proceed to step 4:
55 divided by 20 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 40 away from 55, we end up with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 20

Advancing to step 5:
The number 20 fits into 153 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 527.0
If we subtract 140 from 153, we get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 20

Moving on to step 6:
20 can be fit into 131 6 times, resulting in a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 5276.0
Deduct 120 from 131 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
20 goes into 110 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 5276.5
If we subtract 100 from 110, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5276.55
If we take 100 away from 100, 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.

The final outcome is 5276.55, with a leftover of 0.0.
