We divide 20040251 by 40
Our goal is to divide 20040251 by 40.

Moving on to step 1:
40 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 40

Advancing to step 2:
When dividing 20 by 40, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 40

Let's proceed to step 3:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 200 from 200 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 40

Step 4:
40 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 40

On to step 5:
40 goes into 40 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 501.0
Subtracting 40 from 40 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 40

Let's proceed to step 6:
If we divide 2 by 40, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 5010.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 40

Moving on to step 7:
If we divide 25 by 40, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 50100.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 40

Let's proceed to step 8:
40 goes into 251 6 times with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 501006.0
If we take 240 away from 251, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
40 goes into 110 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 501006.2
If we take 80 away from 110, we end up 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.

Step 10:
When dividing 300 by 40, we get 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 501006.27
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 501006.275
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 12:
0 divided by 40 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 501006.275
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.

Step 13:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 501006.275
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.

The final outcome is 501006.275, with a leftover of 0.0.
