66385417 divided by 665 
We want to divide 66385417 by 665.

On to step 1:
665 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 665

Step 2:
66 divided by 665 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 665

Step 3:
The number 665 fits into 663 0 times, leaving a remainder of 663.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 663 to get 663.
Append the next digit (8) from the dividend to 663 and continue with: 6638 / 665

On to step 4:
The number 665 fits into 6638 9 times, leaving a remainder of 653.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 5985 from 6638 to get 653.
Take the next digit (5) from the dividend and append it to 653, then repeat: 6535 / 665

On to step 5:
6535 divided by 665 is 9 with a remainder of 550.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 5985 from 6535, we get 550.
Grab the next digit (4) from the dividend, add it to 550, then carry on: 5504 / 665

Moving on to step 6:
The number 665 fits into 5504 8 times, leaving a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 998.0
If we subtract 5320 from 5504, we get 184.
Append the next digit (1) from the dividend to 184 and continue with: 1841 / 665

Step 7:
1841 divided by 665 is 2 with a remainder of 511.
The number 2 becomes the next digit in our result. 
Result so far: 9982.0
Subtracting 1330 from 1841 leaves us with 511.
Take the next digit (7) from the dividend and append it to 511, then repeat: 5117 / 665

Step 8:
665 goes into 5117 7 times with a remainder of 462.
Use 7 as the next digit of our solution. 
Result so far: 99827.0
Subtracting 4655 from 5117 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Going ahead to step 9:
665 can be fit into 4620 6 times, resulting in a remainder of 630.
The number 6 becomes the next digit in our result. 
Result so far: 99827.6
The remainder is 630 after subtracting 3990 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 10:
If we divide 6300 by 665, we get 9 and a remainder of 315.
Record the quotient 9 as the next digit in the result. 
Result so far: 99827.69
Deduct 5985 from 6300 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 11:
If we divide 3150 by 665, we get 4 and a remainder of 490.
Write down 4 as next digit of the result. 
Result so far: 99827.694
Subtracting 2660 from 3150 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 12:
The number 665 fits into 4900 7 times, leaving a remainder of 245.
The next digit of our result is 7. 
Result so far: 99827.6947
The remainder is 245 after subtracting 4655 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 13:
665 can be fit into 2450 3 times, resulting in a remainder of 455.
Record the quotient 3 as the next digit in the result. 
Result so far: 99827.69473
If we take 1995 away from 2450, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 14:
The number 665 fits into 4550 6 times, leaving a remainder of 560.
The next digit of our result is 6. 
Result so far: 99827.694736
Subtracting 3990 from 4550 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 15:
665 goes into 5600 8 times with a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 99827.6947368
If we subtract 5320 from 5600, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 16:
665 can be fit into 2800 4 times, resulting in a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 99827.69473684
If we subtract 2660 from 2800, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 99827.69473684 with a remaining 1.4e-07.
