Let's divide 66909865 by 560
We're looking to find how many times 560 goes into 66909865.

Step 1:
560 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 560

Going ahead to step 2:
560 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 560

Let's proceed to step 3:
560 can be fit into 669 1 times, resulting in a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 560 from 669 and we're left with 109.
Take the next digit (0) from the dividend and append it to 109, then repeat: 1090 / 560

Advancing to step 4:
The number 560 fits into 1090 1 times, leaving a remainder of 530.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 560 from 1090 leaves us with 530.
Include the next digit (9) from the dividend after 530, then repeat: 5309 / 560

Moving on to step 5:
When dividing 5309 by 560, we get 9 with a remainder of 269.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
The remainder is 269 after subtracting 5040 from 5309.
Include the next digit (8) from the dividend after 269, then repeat: 2698 / 560

Moving on to step 6:
The number 560 fits into 2698 4 times, leaving a remainder of 458.
Put 4 as the next digit of the answer. 
Result so far: 1194.0
Subtracting 2240 from 2698 leaves us with 458.
Fetch the next digit (6) from the dividend, attach it to 458 and continue: 4586 / 560

Moving on to step 7:
560 goes into 4586 8 times with a remainder of 106.
Record the quotient 8 as the next digit in the result. 
Result so far: 11948.0
Subtracting 4480 from 4586 leaves us with 106.
Fetch the next digit (5) from the dividend, attach it to 106 and continue: 1065 / 560

Step 8:
1065 divided by 560 is 1 with a remainder of 505.
Record the quotient 1 as the next digit in the result. 
Result so far: 119481.0
If we take 560 away from 1065, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 9:
If we divide 5050 by 560, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 119481.9
Subtract 5040 from 5050 to 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:
The number 560 fits into 100 0 times, leaving a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 119481.9
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
560 goes into 1000 1 times with a remainder of 440.
Put 1 as the next digit of the answer. 
Result so far: 119481.901
Subtract 560 from 1000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
If we divide 4400 by 560, we get 7 and a remainder of 480.
Put 7 as the next digit of the answer. 
Result so far: 119481.9017
The remainder is 480 after subtracting 3920 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
4800 divided by 560 is 8 with a remainder of 320.
The next digit of our result is 8. 
Result so far: 119481.90178
Deduct 4480 from 4800 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
If we divide 3200 by 560, we get 5 and a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 119481.901785
If we take 2800 away from 3200, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 15:
When dividing 4000 by 560, we get 7 with a remainder of 80.
The number 7 becomes the next digit in our result. 
Result so far: 119481.9017857
Subtract 3920 from 4000 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
800 divided by 560 is 1 with a remainder of 240.
Record the quotient 1 as the next digit in the result. 
Result so far: 119481.90178571
Subtract 560 from 800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The quotient of the division is 119481.90178571, and the remainder is 2.4e-07.
