We divide 66509767 by 669
We want to divide 66509767 by 669.

On to step 1:
669 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 669

Moving on to step 2:
The number 669 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 669

Step 3:
When dividing 665 by 669, we get 0 with a remainder of 665.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 665, we get 665.
Bring next digit (0) of the dividend behind the 665 and repeat the process: 6650 / 669

Going ahead to step 4:
When dividing 6650 by 669, we get 9 with a remainder of 629.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 6021 away from 6650, we end up with 629.
Bring next digit (9) of the dividend behind the 629 and repeat the process: 6299 / 669

On to step 5:
If we divide 6299 by 669, we get 9 and a remainder of 278.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 6021 from 6299, we get 278.
Take the next digit (7) from the dividend and append it to 278, then repeat: 2787 / 669

Advancing to step 6:
If we divide 2787 by 669, we get 4 and a remainder of 111.
Put 4 as the next digit of the answer. 
Result so far: 994.0
Deduct 2676 from 2787 and we're left with 111.
Append the next digit (6) from the dividend to 111 and continue with: 1116 / 669

On to step 7:
If we divide 1116 by 669, we get 1 and a remainder of 447.
Record the quotient 1 as the next digit in the result. 
Result so far: 9941.0
Deduct 669 from 1116 and we're left with 447.
Include the next digit (7) from the dividend after 447, then repeat: 4477 / 669

On to step 8:
When dividing 4477 by 669, we get 6 with a remainder of 463.
Record the quotient 6 as the next digit in the result. 
Result so far: 99416.0
If we take 4014 away from 4477, we end up with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Going ahead to step 9:
669 can be fit into 4630 6 times, resulting in a remainder of 616.
Write down 6 as next digit of the result. 
Result so far: 99416.6
The remainder is 616 after subtracting 4014 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Going ahead to step 10:
669 can be fit into 6160 9 times, resulting in a remainder of 139.
The next digit of our result is 9. 
Result so far: 99416.69
If we take 6021 away from 6160, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 11:
669 can be fit into 1390 2 times, resulting in a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 99416.692
Subtract 1338 from 1390 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
If we divide 520 by 669, we get 0 and a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 99416.692
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 13:
The number 669 fits into 5200 7 times, leaving a remainder of 517.
The next digit of our result is 7. 
Result so far: 99416.69207
The remainder is 517 after subtracting 4683 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Going ahead to step 14:
669 can be fit into 5170 7 times, resulting in a remainder of 487.
The number 7 becomes the next digit in our result. 
Result so far: 99416.692077
Subtracting 4683 from 5170 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

The quotient of the division is 99416.692077, and the remainder is 4.87e-05.
