667591 ÷ 66 
Our goal is to divide 667591 by 66.

Going ahead to step 1:
If we divide 6 by 66, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 66

Let's proceed to step 2:
When dividing 66 by 66, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 66 away from 66, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 66

On to step 3:
66 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 66

Advancing to step 4:
When dividing 75 by 66, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
The remainder is 9 after subtracting 66 from 75.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 66

Advancing to step 5:
99 divided by 66 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1011.0
The remainder is 33 after subtracting 66 from 99.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 66

Moving on to step 6:
66 can be fit into 331 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 10115.0
Deduct 330 from 331 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 66 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10115.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 66, we get 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 10115.01
If we subtract 66 from 100, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
When dividing 340 by 66, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10115.015
If we subtract 330 from 340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
66 goes into 100 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 10115.0151
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
When dividing 340 by 66, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10115.01515
If we subtract 330 from 340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
66 can be fit into 100 1 times, resulting in a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 10115.015151
Subtract 66 from 100 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
When dividing 340 by 66, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10115.0151515
Subtracting 330 from 340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 66 fits into 100 1 times, leaving a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 10115.01515151
Subtract 66 from 100 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 10115.01515151 with a remaining 3.4e-08.
