52156658 divided by 666 
Our goal is to divide 52156658 by 666.

Going ahead to step 1:
5 divided by 666 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 666

Advancing to step 2:
52 divided by 666 is 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 666

Moving on to step 3:
666 goes into 521 0 times with a remainder of 521.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 521 and we're left with 521.
Bring next digit (5) of the dividend behind the 521 and repeat the process: 5215 / 666

Moving on to step 4:
666 goes into 5215 7 times with a remainder of 553.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 553 after subtracting 4662 from 5215.
Grab the next digit (6) from the dividend, add it to 553, then carry on: 5536 / 666

Let's proceed to step 5:
666 goes into 5536 8 times with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we subtract 5328 from 5536, we get 208.
Take the next digit (6) from the dividend and append it to 208, then repeat: 2086 / 666

Step 6:
2086 divided by 666 is 3 with a remainder of 88.
Use 3 as the next digit of our solution. 
Result so far: 783.0
The remainder is 88 after subtracting 1998 from 2086.
Grab the next digit (5) from the dividend, add it to 88, then carry on: 885 / 666

Let's proceed to step 7:
The number 666 fits into 885 1 times, leaving a remainder of 219.
Use 1 as the next digit of our solution. 
Result so far: 7831.0
If we subtract 666 from 885, we get 219.
Fetch the next digit (8) from the dividend, attach it to 219 and continue: 2198 / 666

On to step 8:
666 can be fit into 2198 3 times, resulting in a remainder of 200.
Write down 3 as next digit of the result. 
Result so far: 78313.0
If we take 1998 away from 2198, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 9:
The number 666 fits into 2000 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 78313.3
Deduct 1998 from 2000 and we're left 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.

On to step 10:
If we divide 20 by 666, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 78313.3
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.

Advancing to step 11:
If we divide 200 by 666, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 78313.3
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 78313.3 with a remaining 0.02.
