We're dividing 715743 by 40 
Our goal is to divide 715743 by 40.

On to 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
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 40

Step 2:
71 divided by 40 is 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 31 after subtracting 40 from 71.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 40

Moving on 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
Subtract 280 from 315 to get 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 40

Advancing to step 4:
When dividing 357 by 40, we get 8 with a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 178.0
Subtract 320 from 357 to get 37.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 40

On to step 5:
374 divided by 40 is 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 1789.0
Subtracting 360 from 374 leaves us with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 40

On to step 6:
When dividing 143 by 40, we get 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 17893.0
The remainder is 23 after subtracting 120 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
230 divided by 40 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 17893.5
Subtracting 200 from 230 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
When dividing 300 by 40, we get 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 17893.57
Subtract 280 from 300 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.

Moving on to step 9:
When dividing 200 by 40, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 17893.575
Subtracting 200 from 200 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.

Let's proceed to step 10:
0 divided by 40 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17893.575
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.

On to step 11:
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: 17893.575
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.

Our division results in 17893.575 with a remaining 0.0.
