We divide 690023 by 66
Let's see how many times 66 fits into 690023.

Moving on to step 1:
66 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 66

Going ahead to step 2:
If we divide 69 by 66, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 66 from 69, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 66

Advancing to step 3:
If we divide 30 by 66, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 30, we end up with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 66

On to step 4:
66 goes into 300 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 104.0
If we subtract 264 from 300, we get 36.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 66

Moving on to step 5:
66 can be fit into 362 5 times, resulting in a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 1045.0
If we subtract 330 from 362, we get 32.
Take the next digit (3) from the dividend and append it to 32, then repeat: 323 / 66

On to step 6:
323 divided by 66 is 4 with a remainder of 59.
The next digit of our result is 4. 
Result so far: 10454.0
Subtract 264 from 323 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
66 can be fit into 590 8 times, resulting in a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 10454.8
Deduct 528 from 590 and we're left with 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 8:
66 can be fit into 620 9 times, resulting in a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 10454.89
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.

On to step 9:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 10454.893
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.

Step 10:
When dividing 620 by 66, we get 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 10454.8939
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.

Going ahead to step 11:
If we divide 260 by 66, we get 3 and a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 10454.89393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
66 goes into 620 9 times with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 10454.893939
Deduct 594 from 620 and we're left 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.

Step 13:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 10454.8939393
Deduct 198 from 260 and we're left with 62.
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 14:
When dividing 620 by 66, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 10454.89393939
The remainder is 26 after subtracting 594 from 620.
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 10454.89393939 with a remainder of 2.6e-08.
