We look at the division of 510536 by 66 
We want to figure out the number of times 510536 can be divided by 66.

Advancing to step 1:
66 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 66

Moving on to step 2:
66 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 66

Moving on to step 3:
66 can be fit into 510 7 times, resulting in a remainder of 48.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 462 from 510 and we're left with 48.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 66

On to step 4:
If we divide 485 by 66, we get 7 and a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 462 from 485 to get 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 66

Let's proceed to step 5:
The number 66 fits into 233 3 times, leaving a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 773.0
The remainder is 35 after subtracting 198 from 233.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 66

Step 6:
When dividing 356 by 66, we get 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 7735.0
Deduct 330 from 356 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
If we divide 260 by 66, we get 3 and a remainder of 62.
The next digit of our result is 3. 
Result so far: 7735.3
The remainder is 62 after subtracting 198 from 260.
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 66 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 7735.39
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
260 divided by 66 is 3 with a remainder of 62.
The next digit of our result is 3. 
Result so far: 7735.393
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
66 goes into 620 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 7735.3939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 7735.39393
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
620 divided by 66 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 7735.393939
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
260 divided by 66 is 3 with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 7735.3939393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 14:
If we divide 620 by 66, we get 9 and a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 7735.39393939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 7735.39393939 with a balance of 2.6e-08.
