We look at the division of 255800 by 66 
Let's see how many times 66 fits into 255800.

Going ahead to step 1:
The number 66 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 66

Moving on to step 2:
66 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 66

Let's proceed to step 3:
255 divided by 66 is 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 198 from 255 leaves us with 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 66

Let's proceed to step 4:
578 divided by 66 is 8 with a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Deduct 528 from 578 and we're left with 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 66

On to step 5:
66 goes into 500 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 387.0
Deduct 462 from 500 and we're left with 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 66

Advancing to step 6:
If we divide 380 by 66, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 3875.0
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
66 goes into 500 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 3875.7
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 3875.75
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 3875.757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
380 divided by 66 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 3875.7575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 66, we get 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 3875.75757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
380 divided by 66 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3875.757575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
When dividing 500 by 66, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 3875.7575757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 3875.75757575
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 3875.75757575 with a remaining 5e-08.
