Let's divide 40870 by 1
Our goal is to divide 40870 by 1.

On to step 1:
When dividing 4 by 1, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Let's proceed to step 2:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 0 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

On to step 3:
If we divide 8 by 1, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 408.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

On to step 4:
7 divided by 1 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 4087.0
Subtracting 7 from 7 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Let's proceed to step 5:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40870.0
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.

Advancing to step 6:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40870.0
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.

On to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40870.0
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.

The final result is 40870.0 with a remainder of 0.0.
