We're dividing 17872712 by 661 
Our goal is to divide 17872712 by 661.

On to step 1:
If we divide 1 by 661, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 661

Advancing to step 2:
If we divide 17 by 661, we get 0 and a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 661

On to step 3:
The number 661 fits into 178 0 times, leaving a remainder of 178.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 178 after subtracting 0 from 178.
Fetch the next digit (7) from the dividend, attach it to 178 and continue: 1787 / 661

Going ahead to step 4:
661 can be fit into 1787 2 times, resulting in a remainder of 465.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1322 away from 1787, we end up with 465.
Fetch the next digit (2) from the dividend, attach it to 465 and continue: 4652 / 661

Advancing to step 5:
661 can be fit into 4652 7 times, resulting in a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 4627 away from 4652, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 661

Advancing to step 6:
When dividing 257 by 661, we get 0 with a remainder of 257.
Use 0 as the next digit of our solution. 
Result so far: 270.0
Deduct 0 from 257 and we're left with 257.
Include the next digit (1) from the dividend after 257, then repeat: 2571 / 661

Advancing to step 7:
The number 661 fits into 2571 3 times, leaving a remainder of 588.
Use 3 as the next digit of our solution. 
Result so far: 2703.0
The remainder is 588 after subtracting 1983 from 2571.
Fetch the next digit (2) from the dividend, attach it to 588 and continue: 5882 / 661

On to step 8:
When dividing 5882 by 661, we get 8 with a remainder of 594.
Use 8 as the next digit of our solution. 
Result so far: 27038.0
If we take 5288 away from 5882, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 9:
The number 661 fits into 5940 8 times, leaving a remainder of 652.
Record the quotient 8 as the next digit in the result. 
Result so far: 27038.8
Deduct 5288 from 5940 and we're left with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Let's proceed to step 10:
661 goes into 6520 9 times with a remainder of 571.
Put 9 as the next digit of the answer. 
Result so far: 27038.89
If we take 5949 away from 6520, we end up with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Moving on to step 11:
661 can be fit into 5710 8 times, resulting in a remainder of 422.
Record the quotient 8 as the next digit in the result. 
Result so far: 27038.898
If we take 5288 away from 5710, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 12:
The number 661 fits into 4220 6 times, leaving a remainder of 254.
The next digit of our result is 6. 
Result so far: 27038.8986
Deduct 3966 from 4220 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 13:
2540 divided by 661 is 3 with a remainder of 557.
Use 3 as the next digit of our solution. 
Result so far: 27038.89863
If we take 1983 away from 2540, we end up with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Let's proceed to step 14:
The number 661 fits into 5570 8 times, leaving a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 27038.898638
The remainder is 282 after subtracting 5288 from 5570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 15:
The number 661 fits into 2820 4 times, leaving a remainder of 176.
Use 4 as the next digit of our solution. 
Result so far: 27038.8986384
If we subtract 2644 from 2820, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 16:
When dividing 1760 by 661, we get 2 with a remainder of 438.
The number 2 becomes the next digit in our result. 
Result so far: 27038.89863842
Subtracting 1322 from 1760 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

In conclusion, the division gives 27038.89863842 with a balance of 4.38e-07.
