We look at the division of 42846012 by 510 
We're looking to find how many times 510 goes into 42846012.

Going ahead to step 1:
510 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 510

On to step 2:
If we divide 42 by 510, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 510

Step 3:
The number 510 fits into 428 0 times, leaving a remainder of 428.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 428 after subtracting 0 from 428.
Bring next digit (4) of the dividend behind the 428 and repeat the process: 4284 / 510

Moving on to step 4:
4284 divided by 510 is 8 with a remainder of 204.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 4080 from 4284 leaves us with 204.
Take the next digit (6) from the dividend and append it to 204, then repeat: 2046 / 510

Going ahead to step 5:
If we divide 2046 by 510, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtracting 2040 from 2046 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 510

Step 6:
When dividing 60 by 510, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 840.0
If we subtract 0 from 60, we get 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 510

Let's proceed to step 7:
When dividing 601 by 510, we get 1 with a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 8401.0
If we take 510 away from 601, we end up with 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 510

Going ahead to step 8:
510 goes into 912 1 times with a remainder of 402.
Record the quotient 1 as the next digit in the result. 
Result so far: 84011.0
Deduct 510 from 912 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 9:
The number 510 fits into 4020 7 times, leaving a remainder of 450.
Use 7 as the next digit of our solution. 
Result so far: 84011.7
Subtract 3570 from 4020 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 10:
510 goes into 4500 8 times with a remainder of 420.
Put 8 as the next digit of the answer. 
Result so far: 84011.78
Subtracting 4080 from 4500 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
When dividing 4200 by 510, we get 8 with a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 84011.788
The remainder is 120 after subtracting 4080 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 84011.788, with a leftover of 0.012.
