We're dividing 42084016 by 510 
We want to divide 42084016 by 510.

Advancing to step 1:
The number 510 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 510

Going ahead to step 2:
510 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 510

Moving on to step 3:
If we divide 420 by 510, we get 0 and a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 420 after subtracting 0 from 420.
Fetch the next digit (8) from the dividend, attach it to 420 and continue: 4208 / 510

Advancing to step 4:
510 can be fit into 4208 8 times, resulting in a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 4080 from 4208, we get 128.
Take the next digit (4) from the dividend and append it to 128, then repeat: 1284 / 510

Let's proceed to step 5:
1284 divided by 510 is 2 with a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtract 1020 from 1284 to get 264.
Append the next digit (0) from the dividend to 264 and continue with: 2640 / 510

Let's proceed to step 6:
2640 divided by 510 is 5 with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 825.0
If we subtract 2550 from 2640, we get 90.
Bring next digit (1) of the dividend behind the 90 and repeat the process: 901 / 510

Let's proceed to step 7:
When dividing 901 by 510, we get 1 with a remainder of 391.
The number 1 becomes the next digit in our result. 
Result so far: 8251.0
Subtract 510 from 901 to get 391.
Fetch the next digit (6) from the dividend, attach it to 391 and continue: 3916 / 510

Let's proceed to step 8:
510 goes into 3916 7 times with a remainder of 346.
Use 7 as the next digit of our solution. 
Result so far: 82517.0
Deduct 3570 from 3916 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 9:
If we divide 3460 by 510, we get 6 and a remainder of 400.
The number 6 becomes the next digit in our result. 
Result so far: 82517.6
The remainder is 400 after subtracting 3060 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 10:
510 goes into 4000 7 times with a remainder of 430.
Write down 7 as next digit of the result. 
Result so far: 82517.67
If we take 3570 away from 4000, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 11:
If we divide 4300 by 510, we get 8 and a remainder of 220.
The number 8 becomes the next digit in our result. 
Result so far: 82517.678
If we take 4080 away from 4300, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 12:
If we divide 2200 by 510, we get 4 and a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 82517.6784
If we take 2040 away from 2200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
When dividing 1600 by 510, we get 3 with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 82517.67843
Subtracting 1530 from 1600 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.

Let's proceed to step 14:
The number 510 fits into 700 1 times, leaving a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 82517.678431
Subtracting 510 from 700 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 15:
The number 510 fits into 1900 3 times, leaving a remainder of 370.
The number 3 becomes the next digit in our result. 
Result so far: 82517.6784313
Subtract 1530 from 1900 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 16:
When dividing 3700 by 510, we get 7 with a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 82517.67843137
Subtract 3570 from 3700 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

After the division, we end up with 82517.67843137 and a remainder of 1.3e-07.
