We're dividing 715553 by 40 
We want to divide 715553 by 40.

Step 1:
The number 40 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 40

Advancing to step 2:
40 can be fit into 71 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 40 from 71 leaves us with 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 40

Advancing to step 3:
315 divided by 40 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 280 from 315 and we're left with 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 40

Going ahead to step 4:
40 can be fit into 355 8 times, resulting in a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Subtract 320 from 355 to get 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 40

Going ahead to step 5:
If we divide 355 by 40, we get 8 and a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 1788.0
Subtracting 320 from 355 leaves us with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 40

Going ahead to step 6:
If we divide 353 by 40, we get 8 and a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 17888.0
Deduct 320 from 353 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
If we divide 330 by 40, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 17888.8
If we take 320 away from 330, we end up 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.

Moving on to step 8:
The number 40 fits into 100 2 times, leaving a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 17888.82
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 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 17888.825
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.

Step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17888.825
Subtracting 0 from 0 leaves us 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.

On to step 11:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17888.825
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.

The quotient of the division is 17888.825, and the remainder is 0.0.
