We look at the division of 712160 by 40 
We want to figure out the number of times 712160 can be divided by 40.

Moving on to step 1:
If we divide 7 by 40, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 40

On 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.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 40

Advancing to step 3:
40 goes into 312 7 times with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 280 from 312 and we're left with 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 40

Moving on to step 4:
When dividing 321 by 40, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
Subtract 320 from 321 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 40

Going ahead to step 5:
40 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 1780.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 40

Advancing to step 6:
40 can be fit into 160 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 17804.0
If we take 160 away from 160, 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.

Going ahead to step 7:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17804.0
Deduct 0 from 0 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.

Step 8:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17804.0
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 17804.0, and the remainder is 0.0.
