Let's divide 669761 by 66
Our goal is to divide 669761 by 66.

Advancing to step 1:
If we divide 6 by 66, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 66

Moving on to step 2:
66 goes into 66 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 66 from 66 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 66

Moving on to step 3:
66 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 66

Let's proceed to step 4:
97 divided by 66 is 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we take 66 away from 97, we end up with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 66

Step 5:
66 can be fit into 316 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 1014.0
If we subtract 264 from 316, we get 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 66

Going ahead to step 6:
The number 66 fits into 521 7 times, leaving a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 10147.0
Deduct 462 from 521 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
When dividing 590 by 66, we get 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 10147.8
The remainder is 62 after subtracting 528 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
If we divide 620 by 66, we get 9 and a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 10147.89
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
260 divided by 66 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 10147.893
Subtract 198 from 260 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
620 divided by 66 is 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 10147.8939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 10147.89393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
If we divide 620 by 66, we get 9 and a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 10147.893939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
260 divided by 66 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 10147.8939393
Subtract 198 from 260 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 14:
66 can be fit into 620 9 times, resulting in a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 10147.89393939
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 10147.89393939 with a remainder of 2.6e-08.
