We look at the division of 64420032 by 510 
Let's see how many times 510 fits into 64420032.

Advancing to step 1:
If we divide 6 by 510, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 510

Step 2:
510 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 510

Step 3:
510 can be fit into 644 1 times, resulting in a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 510 from 644 and we're left with 134.
Include the next digit (2) from the dividend after 134, then repeat: 1342 / 510

Moving on to step 4:
510 goes into 1342 2 times with a remainder of 322.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 322 after subtracting 1020 from 1342.
Take the next digit (0) from the dividend and append it to 322, then repeat: 3220 / 510

Moving on to step 5:
3220 divided by 510 is 6 with a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 126.0
Subtracting 3060 from 3220 leaves us with 160.
Fetch the next digit (0) from the dividend, attach it to 160 and continue: 1600 / 510

Going ahead to step 6:
When dividing 1600 by 510, we get 3 with a remainder of 70.
The next digit of our result is 3. 
Result so far: 1263.0
If we take 1530 away from 1600, we end up with 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 510

Going ahead to step 7:
If we divide 703 by 510, we get 1 and a remainder of 193.
Record the quotient 1 as the next digit in the result. 
Result so far: 12631.0
Subtracting 510 from 703 leaves us with 193.
Include the next digit (2) from the dividend after 193, then repeat: 1932 / 510

Going ahead to step 8:
510 can be fit into 1932 3 times, resulting in a remainder of 402.
The next digit of our result is 3. 
Result so far: 126313.0
Subtract 1530 from 1932 to get 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:
510 can be fit into 4020 7 times, resulting in a remainder of 450.
Write down 7 as next digit of the result. 
Result so far: 126313.7
If we take 3570 away from 4020, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
If we divide 4500 by 510, we get 8 and a remainder of 420.
Record the quotient 8 as the next digit in the result. 
Result so far: 126313.78
If we subtract 4080 from 4500, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 11:
The number 510 fits into 4200 8 times, leaving a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 126313.788
Subtract 4080 from 4200 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 126313.788 and a remainder of 0.012.
