Let's divide 66392371 by 305
Our goal is to divide 66392371 by 305.

Let's proceed to step 1:
6 divided by 305 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 305

Moving on to step 2:
305 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 305

Going ahead to step 3:
When dividing 663 by 305, we get 2 with a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 53 after subtracting 610 from 663.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 305

Going ahead to step 4:
The number 305 fits into 539 1 times, leaving a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 234 after subtracting 305 from 539.
Take the next digit (2) from the dividend and append it to 234, then repeat: 2342 / 305

Going ahead to step 5:
305 can be fit into 2342 7 times, resulting in a remainder of 207.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
Deduct 2135 from 2342 and we're left with 207.
Include the next digit (3) from the dividend after 207, then repeat: 2073 / 305

On to step 6:
305 goes into 2073 6 times with a remainder of 243.
Write down 6 as next digit of the result. 
Result so far: 2176.0
Subtract 1830 from 2073 to get 243.
Bring next digit (7) of the dividend behind the 243 and repeat the process: 2437 / 305

Moving on to step 7:
When dividing 2437 by 305, we get 7 with a remainder of 302.
Record the quotient 7 as the next digit in the result. 
Result so far: 21767.0
Subtract 2135 from 2437 to get 302.
Include the next digit (1) from the dividend after 302, then repeat: 3021 / 305

Moving on to step 8:
3021 divided by 305 is 9 with a remainder of 276.
Record the quotient 9 as the next digit in the result. 
Result so far: 217679.0
Subtract 2745 from 3021 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 9:
If we divide 2760 by 305, we get 9 and a remainder of 15.
The next digit of our result is 9. 
Result so far: 217679.9
Subtract 2745 from 2760 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
If we divide 150 by 305, we get 0 and a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 217679.9
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
If we divide 1500 by 305, we get 4 and a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 217679.904
Subtract 1220 from 1500 to 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.

Let's proceed to step 12:
The number 305 fits into 2800 9 times, leaving a remainder of 55.
The next digit of our result is 9. 
Result so far: 217679.9049
Subtract 2745 from 2800 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
The number 305 fits into 550 1 times, leaving a remainder of 245.
Write down 1 as next digit of the result. 
Result so far: 217679.90491
Subtract 305 from 550 to get 245.
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 14:
305 can be fit into 2450 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 217679.904918
Subtracting 2440 from 2450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 15:
The number 305 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 217679.904918
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 16:
305 goes into 1000 3 times with a remainder of 85.
The number 3 becomes the next digit in our result. 
Result so far: 217679.90491803
If we take 915 away from 1000, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 217679.90491803 and a remainder of 8.5e-08.
