We divide 815330 by 40
Let's see how many times 40 fits into 815330.

Advancing to step 1:
The number 40 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 40

Advancing to step 2:
81 divided by 40 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 80 from 81 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 40

Moving on to step 3:
The number 40 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 40

On to step 4:
If we divide 153 by 40, we get 3 and a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
Subtract 120 from 153 to get 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 40

Let's proceed to step 5:
40 goes into 333 8 times with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 2038.0
If we take 320 away from 333, we end up with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 40

Going ahead to step 6:
130 divided by 40 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 20383.0
If we subtract 120 from 130, 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.

Advancing to step 7:
100 divided by 40 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 20383.2
Subtracting 80 from 100 leaves us 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.

On to step 8:
40 goes into 200 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 20383.25
If we take 200 away from 200, 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.

Moving on to step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20383.25
Subtract 0 from 0 to 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:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20383.25
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.

After the division, we end up with 20383.25 and a remainder of 0.0.
