We look at the division of 42302419 by 515 
Let's see how many times 515 fits into 42302419.

Advancing to step 1:
The number 515 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 515

Going ahead to step 2:
42 divided by 515 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 515

On to step 3:
423 divided by 515 is 0 with a remainder of 423.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 423, we get 423.
Bring next digit (0) of the dividend behind the 423 and repeat the process: 4230 / 515

Moving on to step 4:
The number 515 fits into 4230 8 times, leaving a remainder of 110.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 4120 from 4230 and we're left with 110.
Append the next digit (2) from the dividend to 110 and continue with: 1102 / 515

Going ahead to step 5:
1102 divided by 515 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Deduct 1030 from 1102 and we're left with 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 515

Advancing to step 6:
515 can be fit into 724 1 times, resulting in a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 821.0
If we take 515 away from 724, we end up with 209.
Include the next digit (1) from the dividend after 209, then repeat: 2091 / 515

Moving on to step 7:
515 can be fit into 2091 4 times, resulting in a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 8214.0
Deduct 2060 from 2091 and we're left with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 515

Let's proceed to step 8:
319 divided by 515 is 0 with a remainder of 319.
Write down 0 as next digit of the result. 
Result so far: 82140.0
Subtract 0 from 319 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

On to step 9:
515 goes into 3190 6 times with a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 82140.6
Subtracting 3090 from 3190 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
When dividing 1000 by 515, we get 1 with a remainder of 485.
Use 1 as the next digit of our solution. 
Result so far: 82140.61
If we take 515 away from 1000, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 11:
515 goes into 4850 9 times with a remainder of 215.
Use 9 as the next digit of our solution. 
Result so far: 82140.619
Deduct 4635 from 4850 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 12:
If we divide 2150 by 515, we get 4 and a remainder of 90.
Use 4 as the next digit of our solution. 
Result so far: 82140.6194
Subtract 2060 from 2150 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 13:
900 divided by 515 is 1 with a remainder of 385.
Record the quotient 1 as the next digit in the result. 
Result so far: 82140.61941
Subtracting 515 from 900 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 14:
515 goes into 3850 7 times with a remainder of 245.
The number 7 becomes the next digit in our result. 
Result so far: 82140.619417
If we subtract 3605 from 3850, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 15:
When dividing 2450 by 515, we get 4 with a remainder of 390.
Write down 4 as next digit of the result. 
Result so far: 82140.6194174
Deduct 2060 from 2450 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 16:
515 can be fit into 3900 7 times, resulting in a remainder of 295.
The next digit of our result is 7. 
Result so far: 82140.61941747
Subtracting 3605 from 3900 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

The final outcome is 82140.61941747, with a leftover of 2.95e-07.
