40235042 ÷ 515 
Let's see how many times 515 fits into 40235042.

Let's proceed to step 1:
The number 515 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 515

Step 2:
40 divided by 515 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 515

Moving on to step 3:
When dividing 402 by 515, we get 0 with a remainder of 402.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 402, we get 402.
Grab the next digit (3) from the dividend, add it to 402, then carry on: 4023 / 515

Moving on to step 4:
When dividing 4023 by 515, we get 7 with a remainder of 418.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 3605 away from 4023, we end up with 418.
Fetch the next digit (5) from the dividend, attach it to 418 and continue: 4185 / 515

Step 5:
If we divide 4185 by 515, we get 8 and a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 4120 from 4185 leaves us with 65.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 515

Step 6:
If we divide 650 by 515, we get 1 and a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 781.0
The remainder is 135 after subtracting 515 from 650.
Take the next digit (4) from the dividend and append it to 135, then repeat: 1354 / 515

Let's proceed to step 7:
If we divide 1354 by 515, we get 2 and a remainder of 324.
Record the quotient 2 as the next digit in the result. 
Result so far: 7812.0
Deduct 1030 from 1354 and we're left with 324.
Fetch the next digit (2) from the dividend, attach it to 324 and continue: 3242 / 515

Moving on to step 8:
515 can be fit into 3242 6 times, resulting in a remainder of 152.
Use 6 as the next digit of our solution. 
Result so far: 78126.0
Subtract 3090 from 3242 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 9:
The number 515 fits into 1520 2 times, leaving a remainder of 490.
Write down 2 as next digit of the result. 
Result so far: 78126.2
If we subtract 1030 from 1520, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 10:
4900 divided by 515 is 9 with a remainder of 265.
Use 9 as the next digit of our solution. 
Result so far: 78126.29
If we take 4635 away from 4900, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 11:
The number 515 fits into 2650 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 78126.295
If we subtract 2575 from 2650, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
The number 515 fits into 750 1 times, leaving a remainder of 235.
Use 1 as the next digit of our solution. 
Result so far: 78126.2951
The remainder is 235 after subtracting 515 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 13:
2350 divided by 515 is 4 with a remainder of 290.
Record the quotient 4 as the next digit in the result. 
Result so far: 78126.29514
If we subtract 2060 from 2350, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 14:
2900 divided by 515 is 5 with a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 78126.295145
The remainder is 325 after subtracting 2575 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 15:
3250 divided by 515 is 6 with a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 78126.2951456
Subtract 3090 from 3250 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
If we divide 1600 by 515, we get 3 and a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 78126.29514563
If we take 1545 away from 1600, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

In conclusion, the division gives 78126.29514563 with a balance of 5.5e-08.
