We look at the division of 510465 by 69 
We want to figure out the number of times 510465 can be divided by 69.

Step 1:
5 divided by 69 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 69

Step 2:
69 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 69

On to step 3:
The number 69 fits into 510 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 483 from 510, we get 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 69

Let's proceed to step 4:
When dividing 274 by 69, we get 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we take 207 away from 274, we end up with 67.
Append the next digit (6) from the dividend to 67 and continue with: 676 / 69

Let's proceed to step 5:
When dividing 676 by 69, we get 9 with a remainder of 55.
The next digit of our result is 9. 
Result so far: 739.0
If we subtract 621 from 676, we get 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 69

Going ahead to step 6:
69 goes into 555 8 times with a remainder of 3.
The next digit of our result is 8. 
Result so far: 7398.0
Subtract 552 from 555 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 69, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7398.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 69 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 7398.04
Subtract 276 from 300 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
When dividing 240 by 69, we get 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 7398.043
If we take 207 away from 240, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
330 divided by 69 is 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 7398.0434
Subtract 276 from 330 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
540 divided by 69 is 7 with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 7398.04347
Subtracting 483 from 540 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 12:
69 can be fit into 570 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 7398.043478
The remainder is 18 after subtracting 552 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
69 goes into 180 2 times with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 7398.0434782
Subtracting 138 from 180 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
420 divided by 69 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 7398.04347826
The remainder is 6 after subtracting 414 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 7398.04347826 and a remainder of 6e-09.
