We divide 16485 by 40
We want to figure out the number of times 16485 can be divided by 40.

Let's proceed to step 1:
When dividing 1 by 40, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 40

Going ahead to step 2:
16 divided by 40 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 40

Going ahead to step 3:
The number 40 fits into 164 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 160 from 164 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 40

Moving on to step 4:
If we divide 48 by 40, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Deduct 40 from 48 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 40

Let's proceed to step 5:
40 can be fit into 85 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 412.0
If we subtract 80 from 85, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 6:
If we divide 50 by 40, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 412.1
Subtracting 40 from 50 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
40 goes into 100 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 412.12
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 412.125
The remainder is 0 after subtracting 200 from 200.
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 9:
0 divided by 40 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 412.125
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.

Let's proceed to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 412.125
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 quotient of the division is 412.125, and the remainder is 0.0.
