66421578 divided by 385 
We want to divide 66421578 by 385.

On to step 1:
The number 385 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 385

On to step 2:
385 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
The remainder is 66 after subtracting 0 from 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 385

Let's proceed to step 3:
When dividing 664 by 385, we get 1 with a remainder of 279.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 385 from 664 to get 279.
Grab the next digit (2) from the dividend, add it to 279, then carry on: 2792 / 385

Advancing to step 4:
385 goes into 2792 7 times with a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 2695 away from 2792, we end up with 97.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 385

Moving on to step 5:
The number 385 fits into 971 2 times, leaving a remainder of 201.
Write down 2 as next digit of the result. 
Result so far: 172.0
Subtract 770 from 971 to get 201.
Fetch the next digit (5) from the dividend, attach it to 201 and continue: 2015 / 385

Moving on to step 6:
385 goes into 2015 5 times with a remainder of 90.
The next digit of our result is 5. 
Result so far: 1725.0
If we subtract 1925 from 2015, we get 90.
Bring next digit (7) of the dividend behind the 90 and repeat the process: 907 / 385

Going ahead to step 7:
907 divided by 385 is 2 with a remainder of 137.
Record the quotient 2 as the next digit in the result. 
Result so far: 17252.0
The remainder is 137 after subtracting 770 from 907.
Grab the next digit (8) from the dividend, add it to 137, then carry on: 1378 / 385

Let's proceed to step 8:
1378 divided by 385 is 3 with a remainder of 223.
Write down 3 as next digit of the result. 
Result so far: 172523.0
The remainder is 223 after subtracting 1155 from 1378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 9:
385 goes into 2230 5 times with a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 172523.5
If we take 1925 away from 2230, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 10:
The number 385 fits into 3050 7 times, leaving a remainder of 355.
Use 7 as the next digit of our solution. 
Result so far: 172523.57
Subtract 2695 from 3050 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 11:
The number 385 fits into 3550 9 times, leaving a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 172523.579
Deduct 3465 from 3550 and we're left 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.

Moving on to step 12:
The number 385 fits into 850 2 times, leaving a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 172523.5792
Subtract 770 from 850 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.

Going ahead to step 13:
The number 385 fits into 800 2 times, leaving a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 172523.57922
If we subtract 770 from 800, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 172523.57922, and the remainder is 3e-05.
