66362609 ÷ 977 
We want to divide 66362609 by 977.

Step 1:
6 divided by 977 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 977

Let's proceed to step 2:
When dividing 66 by 977, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 977

On to step 3:
977 goes into 663 0 times with a remainder of 663.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 663, we end up with 663.
Append the next digit (6) from the dividend to 663 and continue with: 6636 / 977

Advancing to step 4:
6636 divided by 977 is 6 with a remainder of 774.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 774 after subtracting 5862 from 6636.
Take the next digit (2) from the dividend and append it to 774, then repeat: 7742 / 977

Advancing to step 5:
When dividing 7742 by 977, we get 7 with a remainder of 903.
Put 7 as the next digit of the answer. 
Result so far: 67.0
If we take 6839 away from 7742, we end up with 903.
Append the next digit (6) from the dividend to 903 and continue with: 9036 / 977

Going ahead to step 6:
When dividing 9036 by 977, we get 9 with a remainder of 243.
The next digit of our result is 9. 
Result so far: 679.0
The remainder is 243 after subtracting 8793 from 9036.
Include the next digit (0) from the dividend after 243, then repeat: 2430 / 977

Advancing to step 7:
The number 977 fits into 2430 2 times, leaving a remainder of 476.
The number 2 becomes the next digit in our result. 
Result so far: 6792.0
Deduct 1954 from 2430 and we're left with 476.
Take the next digit (9) from the dividend and append it to 476, then repeat: 4769 / 977

Advancing to step 8:
If we divide 4769 by 977, we get 4 and a remainder of 861.
The number 4 becomes the next digit in our result. 
Result so far: 67924.0
The remainder is 861 after subtracting 3908 from 4769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8610, and continue the process.

Step 9:
If we divide 8610 by 977, we get 8 and a remainder of 794.
Record the quotient 8 as the next digit in the result. 
Result so far: 67924.8
If we take 7816 away from 8610, we end up with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Going ahead to step 10:
The number 977 fits into 7940 8 times, leaving a remainder of 124.
The number 8 becomes the next digit in our result. 
Result so far: 67924.88
Subtract 7816 from 7940 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

In conclusion, the division gives 67924.88 with a balance of 0.124.
