550902 ÷ 40 
Let's see how many times 40 fits into 550902.

Going ahead to step 1:
40 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 40

Let's proceed to step 2:
The number 40 fits into 55 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 40 from 55 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 40

Going ahead to step 3:
The number 40 fits into 150 3 times, leaving a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 120 away from 150, we end up with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 40

On to step 4:
40 can be fit into 309 7 times, resulting in a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtracting 280 from 309 leaves us with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 40

Going ahead to step 5:
40 can be fit into 290 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 1377.0
If we subtract 280 from 290, we get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 40

Moving on to step 6:
When dividing 102 by 40, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 13772.0
Subtract 80 from 102 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
When dividing 220 by 40, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 13772.5
Deduct 200 from 220 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 8:
200 divided by 40 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 13772.55
Deduct 200 from 200 and we're left 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 13772.55, and the remainder is 0.0.
