64966796 ÷ 990 
Our goal is to divide 64966796 by 990.

Let's proceed to step 1:
6 divided by 990 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 990

On to step 2:
The number 990 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 990

Going ahead to step 3:
990 goes into 649 0 times with a remainder of 649.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 649 after subtracting 0 from 649.
Take the next digit (6) from the dividend and append it to 649, then repeat: 6496 / 990

Moving on to step 4:
6496 divided by 990 is 6 with a remainder of 556.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 5940 from 6496 to get 556.
Fetch the next digit (6) from the dividend, attach it to 556 and continue: 5566 / 990

Moving on to step 5:
The number 990 fits into 5566 5 times, leaving a remainder of 616.
Put 5 as the next digit of the answer. 
Result so far: 65.0
If we take 4950 away from 5566, we end up with 616.
Fetch the next digit (7) from the dividend, attach it to 616 and continue: 6167 / 990

Let's proceed to step 6:
990 goes into 6167 6 times with a remainder of 227.
Put 6 as the next digit of the answer. 
Result so far: 656.0
The remainder is 227 after subtracting 5940 from 6167.
Grab the next digit (9) from the dividend, add it to 227, then carry on: 2279 / 990

Step 7:
2279 divided by 990 is 2 with a remainder of 299.
The number 2 becomes the next digit in our result. 
Result so far: 6562.0
Deduct 1980 from 2279 and we're left with 299.
Include the next digit (6) from the dividend after 299, then repeat: 2996 / 990

Let's proceed to step 8:
2996 divided by 990 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 65623.0
If we subtract 2970 from 2996, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
990 can be fit into 260 0 times, resulting in a remainder of 260.
The next digit of our result is 0. 
Result so far: 65623.0
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
2600 divided by 990 is 2 with a remainder of 620.
Record the quotient 2 as the next digit in the result. 
Result so far: 65623.02
If we take 1980 away from 2600, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 11:
990 goes into 6200 6 times with a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 65623.026
The remainder is 260 after subtracting 5940 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 12:
2600 divided by 990 is 2 with a remainder of 620.
Write down 2 as next digit of the result. 
Result so far: 65623.0262
If we take 1980 away from 2600, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 13:
The number 990 fits into 6200 6 times, leaving a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 65623.02626
If we take 5940 away from 6200, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 14:
990 can be fit into 2600 2 times, resulting in a remainder of 620.
Record the quotient 2 as the next digit in the result. 
Result so far: 65623.026262
The remainder is 620 after subtracting 1980 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 15:
6200 divided by 990 is 6 with a remainder of 260.
Write down 6 as next digit of the result. 
Result so far: 65623.0262626
Subtracting 5940 from 6200 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 16:
990 can be fit into 2600 2 times, resulting in a remainder of 620.
Record the quotient 2 as the next digit in the result. 
Result so far: 65623.02626262
If we subtract 1980 from 2600, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

In conclusion, the division gives 65623.02626262 with a balance of 6.2e-07.
