42950724 ÷ 509 
Our goal is to divide 42950724 by 509.

Going ahead to step 1:
When dividing 4 by 509, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 509

On to step 2:
42 divided by 509 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 509

On to step 3:
509 goes into 429 0 times with a remainder of 429.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 429 leaves us with 429.
Grab the next digit (5) from the dividend, add it to 429, then carry on: 4295 / 509

On to step 4:
When dividing 4295 by 509, we get 8 with a remainder of 223.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 4072 from 4295 to get 223.
Append the next digit (0) from the dividend to 223 and continue with: 2230 / 509

Going ahead to step 5:
When dividing 2230 by 509, we get 4 with a remainder of 194.
Use 4 as the next digit of our solution. 
Result so far: 84.0
The remainder is 194 after subtracting 2036 from 2230.
Include the next digit (7) from the dividend after 194, then repeat: 1947 / 509

Advancing to step 6:
The number 509 fits into 1947 3 times, leaving a remainder of 420.
Put 3 as the next digit of the answer. 
Result so far: 843.0
If we subtract 1527 from 1947, we get 420.
Take the next digit (2) from the dividend and append it to 420, then repeat: 4202 / 509

Moving on to step 7:
509 goes into 4202 8 times with a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 8438.0
Deduct 4072 from 4202 and we're left with 130.
Include the next digit (4) from the dividend after 130, then repeat: 1304 / 509

Let's proceed to step 8:
1304 divided by 509 is 2 with a remainder of 286.
Use 2 as the next digit of our solution. 
Result so far: 84382.0
If we take 1018 away from 1304, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 9:
When dividing 2860 by 509, we get 5 with a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 84382.5
Subtract 2545 from 2860 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 10:
509 goes into 3150 6 times with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 84382.56
The remainder is 96 after subtracting 3054 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
960 divided by 509 is 1 with a remainder of 451.
Write down 1 as next digit of the result. 
Result so far: 84382.561
The remainder is 451 after subtracting 509 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Step 12:
If we divide 4510 by 509, we get 8 and a remainder of 438.
Put 8 as the next digit of the answer. 
Result so far: 84382.5618
Subtracting 4072 from 4510 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Advancing to step 13:
The number 509 fits into 4380 8 times, leaving a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 84382.56188
Deduct 4072 from 4380 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The final outcome is 84382.56188, with a leftover of 0.000308.
