690471 divided by 66 
Let's see how many times 66 fits into 690471.

On to step 1:
6 divided by 66 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 66

Moving on to step 2:
When dividing 69 by 66, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 66 from 69 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 66

Advancing to step 3:
If we divide 30 by 66, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 66

Going ahead to step 4:
66 can be fit into 304 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Subtracting 264 from 304 leaves us with 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 66

Step 5:
407 divided by 66 is 6 with a remainder of 11.
The next digit of our result is 6. 
Result so far: 1046.0
Subtracting 396 from 407 leaves us with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 66

Let's proceed to step 6:
111 divided by 66 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 10461.0
The remainder is 45 after subtracting 66 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
The number 66 fits into 450 6 times, leaving a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 10461.6
The remainder is 54 after subtracting 396 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
540 divided by 66 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 10461.68
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
66 goes into 120 1 times with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 10461.681
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 10461.6818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
The number 66 fits into 120 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 10461.68181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 12:
When dividing 540 by 66, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 10461.681818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
66 can be fit into 120 1 times, resulting in a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 10461.6818181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 14:
If we divide 540 by 66, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 10461.68181818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 10461.68181818, with a leftover of 1.2e-08.
