We're dividing 259255 by 66 
Let's see how many times 66 fits into 259255.

Going ahead to step 1:
66 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 66

Advancing to step 2:
25 divided by 66 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 66

Let's proceed to step 3:
When dividing 259 by 66, we get 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 198 from 259 to get 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 66

Advancing to step 4:
66 can be fit into 612 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 18 after subtracting 594 from 612.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 66

Moving on to step 5:
66 can be fit into 185 2 times, resulting in a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 392.0
If we subtract 132 from 185, we get 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 66

Going ahead to step 6:
66 can be fit into 535 8 times, resulting in a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 3928.0
If we subtract 528 from 535, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 66 fits into 70 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 3928.1
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
66 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3928.1
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
If we divide 400 by 66, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3928.106
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
66 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3928.106
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
66 goes into 400 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 3928.10606
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
If we divide 40 by 66, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3928.10606
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
When dividing 400 by 66, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3928.1060606
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
When dividing 40 by 66, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3928.1060606
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 3928.1060606 with a remainder of 4e-08.
