12502715 divided by 40 
We want to divide 12502715 by 40.

Step 1:
If we divide 1 by 40, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 40

Advancing to step 2:
12 divided by 40 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 40

Advancing to step 3:
40 can be fit into 125 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 120 from 125 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 40

Step 4:
The number 40 fits into 50 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 40 from 50 leaves us with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 40

Moving on to step 5:
When dividing 102 by 40, we get 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 312.0
If we take 80 away from 102, we end up with 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 40

Let's proceed to step 6:
40 goes into 227 5 times with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 3125.0
If we take 200 away from 227, we end up with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 40

Advancing to step 7:
When dividing 271 by 40, we get 6 with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 31256.0
If we subtract 240 from 271, we get 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 40

Step 8:
315 divided by 40 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 312567.0
If we subtract 280 from 315, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
40 goes into 350 8 times with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 312567.8
Subtract 320 from 350 to get 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.
The next digit of our result is 7. 
Result so far: 312567.87
If we subtract 280 from 300, we 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:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 312567.875
Subtract 200 from 200 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.

On to step 12:
When dividing 0 by 40, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 312567.875
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.

Moving on to step 13:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 312567.875
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.

Our division results in 312567.875 with a remaining 0.0.
