We look at the division of 66605831 by 1 
Our goal is to divide 66605831 by 1.

Advancing to step 1:
1 goes into 6 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

On to step 2:
When dividing 6 by 1, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 6 from 6 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Moving on to step 3:
6 divided by 1 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 666.0
The remainder is 0 after subtracting 6 from 6.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Advancing to step 4:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6660.0
Subtract 0 from 0 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Step 5:
The number 1 fits into 5 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 66605.0
If we take 5 away from 5, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Going ahead to step 6:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 666058.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Step 7:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 6660583.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Moving on to step 8:
If we divide 1 by 1, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 66605831.0
If we subtract 1 from 1, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 66605831.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 66605831.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 66605831.0 with a remainder of 0.0.
