278128 ÷ 66 
We're looking to find how many times 66 goes into 278128.

Going ahead to step 1:
When dividing 2 by 66, we get 0 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 (7) from the dividend to 2 and continue with: 27 / 66

Advancing to step 2:
When dividing 27 by 66, we get 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 66

Going ahead to step 3:
66 can be fit into 278 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 264 from 278 and we're left with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 66

Advancing to step 4:
The number 66 fits into 141 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 9 after subtracting 132 from 141.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 66

Advancing to step 5:
66 goes into 92 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 421.0
The remainder is 26 after subtracting 66 from 92.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 66

Let's proceed to step 6:
66 can be fit into 268 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4214.0
Deduct 264 from 268 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.

Moving on to step 7:
66 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 4214.0
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.

Advancing to step 8:
The number 66 fits into 400 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 4214.06
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.

Advancing to step 9:
The number 66 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4214.06
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.

Advancing to step 10:
400 divided by 66 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 4214.0606
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.

Let's proceed to step 11:
66 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4214.0606
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.

On to step 12:
66 can be fit into 400 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4214.060606
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.

Moving on to step 13:
When dividing 40 by 66, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 4214.060606
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.

Going ahead to step 14:
66 can be fit into 400 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 4214.06060606
Deduct 396 from 400 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.

Our division results in 4214.06060606 with a remaining 4e-09.
