We look at the division of 66889744 by 577 
We want to divide 66889744 by 577.

Let's proceed to step 1:
If we divide 6 by 577, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 577

Step 2:
66 divided by 577 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 577

Let's proceed to step 3:
The number 577 fits into 668 1 times, leaving a remainder of 91.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 91 after subtracting 577 from 668.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 577

Step 4:
918 divided by 577 is 1 with a remainder of 341.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 577 away from 918, we end up with 341.
Grab the next digit (9) from the dividend, add it to 341, then carry on: 3419 / 577

Advancing to step 5:
The number 577 fits into 3419 5 times, leaving a remainder of 534.
The next digit of our result is 5. 
Result so far: 115.0
Subtracting 2885 from 3419 leaves us with 534.
Fetch the next digit (7) from the dividend, attach it to 534 and continue: 5347 / 577

Advancing to step 6:
If we divide 5347 by 577, we get 9 and a remainder of 154.
Write down 9 as next digit of the result. 
Result so far: 1159.0
Deduct 5193 from 5347 and we're left with 154.
Include the next digit (4) from the dividend after 154, then repeat: 1544 / 577

On to step 7:
The number 577 fits into 1544 2 times, leaving a remainder of 390.
Record the quotient 2 as the next digit in the result. 
Result so far: 11592.0
If we take 1154 away from 1544, we end up with 390.
Bring next digit (4) of the dividend behind the 390 and repeat the process: 3904 / 577

Let's proceed to step 8:
577 goes into 3904 6 times with a remainder of 442.
Use 6 as the next digit of our solution. 
Result so far: 115926.0
If we take 3462 away from 3904, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Going ahead to step 9:
If we divide 4420 by 577, we get 7 and a remainder of 381.
Put 7 as the next digit of the answer. 
Result so far: 115926.7
The remainder is 381 after subtracting 4039 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 10:
If we divide 3810 by 577, we get 6 and a remainder of 348.
Use 6 as the next digit of our solution. 
Result so far: 115926.76
Subtracting 3462 from 3810 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 11:
577 can be fit into 3480 6 times, resulting in a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 115926.766
Subtract 3462 from 3480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 115926.766, and the remainder is 0.0018.
