531773 ÷ 40 
Our goal is to divide 531773 by 40.

Advancing to step 1:
The number 40 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 40

Moving on to step 2:
40 can be fit into 53 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 40 away from 53, we end up with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 40

On to step 3:
40 goes into 131 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 120 away from 131, we end up with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 40

Going ahead to step 4:
40 goes into 117 2 times with a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 132.0
If we take 80 away from 117, we end up with 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 40

Step 5:
40 can be fit into 377 9 times, resulting in a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 1329.0
Deduct 360 from 377 and we're left with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 40

Going ahead to step 6:
When dividing 173 by 40, we get 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 13294.0
The remainder is 13 after subtracting 160 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
When dividing 130 by 40, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 13294.3
Subtract 120 from 130 to 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.

Advancing to step 8:
When dividing 100 by 40, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 13294.32
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 13294.325
If we subtract 200 from 200, 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.

Going ahead to step 10:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13294.325
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.

Let's proceed to step 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13294.325
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.

The quotient of the division is 13294.325, and the remainder is 0.0.
