678878 divided by 66 
Our goal is to divide 678878 by 66.

Moving on to step 1:
6 divided by 66 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 66

Let's proceed to step 2:
66 can be fit into 67 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 66 away from 67, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 66

Let's proceed to step 3:
66 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 66

Moving on to step 4:
66 can be fit into 188 2 times, resulting in a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 102.0
Subtracting 132 from 188 leaves us with 56.
Fetch the next digit (7) from the dividend, attach it to 56 and continue: 567 / 66

Advancing to step 5:
The number 66 fits into 567 8 times, leaving a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 1028.0
Deduct 528 from 567 and we're left with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 66

On to step 6:
The number 66 fits into 398 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 10286.0
If we take 396 away from 398, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 66 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10286.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 66 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 10286.03
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
The number 66 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 10286.03
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
When dividing 200 by 66, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 10286.0303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10286.0303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
66 can be fit into 200 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 10286.030303
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
If we divide 20 by 66, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 10286.030303
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
When dividing 200 by 66, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 10286.03030303
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 10286.03030303 and a remainder of 2e-09.
