We look at the division of 510451 by 64 
We want to divide 510451 by 64.

On to step 1:
The number 64 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 64

Moving on to step 2:
The number 64 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 64

Going ahead to step 3:
When dividing 510 by 64, we get 7 with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 448 away from 510, we end up with 62.
Include the next digit (4) from the dividend after 62, then repeat: 624 / 64

Step 4:
If we divide 624 by 64, we get 9 and a remainder of 48.
The next digit of our result is 9. 
Result so far: 79.0
Deduct 576 from 624 and we're left with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 64

Moving on to step 5:
64 goes into 485 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 797.0
Deduct 448 from 485 and we're left with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 64

Step 6:
The number 64 fits into 371 5 times, leaving a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 7975.0
Subtract 320 from 371 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
When dividing 510 by 64, we get 7 with a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 7975.7
Subtract 448 from 510 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
620 divided by 64 is 9 with a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 7975.79
If we take 576 away from 620, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
64 can be fit into 440 6 times, resulting in a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 7975.796
The remainder is 56 after subtracting 384 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
64 goes into 560 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 7975.7968
Subtract 512 from 560 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
When dividing 480 by 64, we get 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 7975.79687
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7975.796875
Subtracting 320 from 320 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7975.796875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7975.796875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 7975.796875, with a leftover of 0.0.
