We divide 507569 by 66
We want to divide 507569 by 66.

Moving on to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 66

On to step 2:
66 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 66

Advancing to step 3:
The number 66 fits into 507 7 times, leaving a remainder of 45.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 462 from 507 and we're left with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 66

Moving on to step 4:
66 can be fit into 455 6 times, resulting in a remainder of 59.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 396 from 455 to get 59.
Include the next digit (6) from the dividend after 59, then repeat: 596 / 66

Step 5:
If we divide 596 by 66, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 769.0
Deduct 594 from 596 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 66

Going ahead to step 6:
29 divided by 66 is 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 7690.0
If we take 0 away from 29, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
66 can be fit into 290 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 7690.4
Subtracting 264 from 290 leaves us 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.

Let's proceed to step 8:
If we divide 260 by 66, we get 3 and a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 7690.43
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.

Let's proceed to step 9:
620 divided by 66 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 7690.439
Subtracting 594 from 620 leaves us 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.

Moving on to step 10:
260 divided by 66 is 3 with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 7690.4393
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.

On to step 11:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 7690.43939
Subtracting 594 from 620 leaves us 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.

Let's proceed to step 12:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 7690.439393
Subtracting 198 from 260 leaves us 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.

Moving on to step 13:
When dividing 620 by 66, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 7690.4393939
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.

Let's proceed to step 14:
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: 7690.43939393
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.

After the division, we end up with 7690.43939393 and a remainder of 6.2e-08.
