40587457 ÷ 125 
Let's see how many times 125 fits into 40587457.

Going ahead to step 1:
4 divided by 125 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 125

Step 2:
The number 125 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 125

Going ahead to step 3:
125 can be fit into 405 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 375 from 405 to get 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 125

Moving on to step 4:
If we divide 308 by 125, we get 2 and a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Deduct 250 from 308 and we're left with 58.
Include the next digit (7) from the dividend after 58, then repeat: 587 / 125

Let's proceed to step 5:
125 can be fit into 587 4 times, resulting in a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 324.0
The remainder is 87 after subtracting 500 from 587.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 125

Moving on to step 6:
If we divide 874 by 125, we get 6 and a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 3246.0
Subtract 750 from 874 to get 124.
Append the next digit (5) from the dividend to 124 and continue with: 1245 / 125

Going ahead to step 7:
125 goes into 1245 9 times with a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 32469.0
Deduct 1125 from 1245 and we're left with 120.
Fetch the next digit (7) from the dividend, attach it to 120 and continue: 1207 / 125

Step 8:
1207 divided by 125 is 9 with a remainder of 82.
Write down 9 as next digit of the result. 
Result so far: 324699.0
The remainder is 82 after subtracting 1125 from 1207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
When dividing 820 by 125, we get 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 324699.6
Subtracting 750 from 820 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
The number 125 fits into 700 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 324699.65
Subtracting 625 from 700 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
125 goes into 750 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 324699.656
If we subtract 750 from 750, 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.

Step 12:
If we divide 0 by 125, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 324699.656
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.

Step 13:
125 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: 324699.656
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.

In conclusion, the division gives 324699.656 with a balance of 0.0.
