263259 ÷ 66 
We're looking to find how many times 66 goes into 263259.

Moving on to step 1:
66 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 66

Advancing to step 2:
The number 66 fits into 26 0 times, leaving a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 66

Advancing to step 3:
When dividing 263 by 66, we get 3 with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 198 from 263 to get 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 66

Advancing to step 4:
66 goes into 652 9 times with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 58 after subtracting 594 from 652.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 66

On to step 5:
66 goes into 585 8 times with a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 398.0
Subtracting 528 from 585 leaves us with 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 66

Going ahead to step 6:
66 can be fit into 579 8 times, resulting in a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 3988.0
Subtract 528 from 579 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.

Advancing to step 7:
When dividing 510 by 66, we get 7 with a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 3988.7
The remainder is 48 after subtracting 462 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
480 divided by 66 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 3988.77
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 3988.77 with a balance of 0.018.
