We divide 418042 by 40
Our goal is to divide 418042 by 40.

Moving on to step 1:
40 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 40

Moving on to step 2:
40 goes into 41 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 40 from 41.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 40

On to step 3:
18 divided by 40 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 40

On to step 4:
180 divided by 40 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtract 160 from 180 to get 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 40

Let's proceed to step 5:
204 divided by 40 is 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 1045.0
If we take 200 away from 204, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 40

Moving on to step 6:
If we divide 42 by 40, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 10451.0
If we take 40 away from 42, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 40, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10451.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
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: 10451.05
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.

Moving on to step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10451.05
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.

Moving on to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10451.05
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 10451.05 with a remainder of 0.0.
