80070585 ÷ 40 
We want to divide 80070585 by 40.

Step 1:
40 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 40

Advancing to step 2:
40 can be fit into 80 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 80 from 80, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 40

Let's proceed to step 3:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 40

Moving on to step 4:
If we divide 7 by 40, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 200.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 40

On to step 5:
When dividing 70 by 40, we get 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 2001.0
Subtract 40 from 70 to get 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 40

Moving on to step 6:
40 can be fit into 305 7 times, resulting in a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 20017.0
If we take 280 away from 305, we end up with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 40

Going ahead to step 7:
The number 40 fits into 258 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 200176.0
If we subtract 240 from 258, we get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 40

Step 8:
The number 40 fits into 185 4 times, leaving a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 2001764.0
The remainder is 25 after subtracting 160 from 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
If we divide 250 by 40, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 2001764.6
If we take 240 away from 250, 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.

Advancing to step 10:
The number 40 fits into 100 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2001764.62
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.

Let's proceed to step 11:
If we divide 200 by 40, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2001764.625
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.

Advancing to step 12:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2001764.625
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.

Let's proceed to step 13:
If we divide 0 by 40, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2001764.625
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.

In conclusion, the division gives 2001764.625 with a balance of 0.0.
