64786612 ÷ 990 
Our goal is to divide 64786612 by 990.

Let's proceed to step 1:
990 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 990

Let's proceed to step 2:
When dividing 64 by 990, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 990

On to step 3:
990 can be fit into 647 0 times, resulting in a remainder of 647.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 647 after subtracting 0 from 647.
Append the next digit (8) from the dividend to 647 and continue with: 6478 / 990

Let's proceed to step 4:
990 goes into 6478 6 times with a remainder of 538.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 538 after subtracting 5940 from 6478.
Grab the next digit (6) from the dividend, add it to 538, then carry on: 5386 / 990

On to step 5:
When dividing 5386 by 990, we get 5 with a remainder of 436.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtracting 4950 from 5386 leaves us with 436.
Bring next digit (6) of the dividend behind the 436 and repeat the process: 4366 / 990

Advancing to step 6:
The number 990 fits into 4366 4 times, leaving a remainder of 406.
The next digit of our result is 4. 
Result so far: 654.0
The remainder is 406 after subtracting 3960 from 4366.
Append the next digit (1) from the dividend to 406 and continue with: 4061 / 990

Going ahead to step 7:
The number 990 fits into 4061 4 times, leaving a remainder of 101.
The next digit of our result is 4. 
Result so far: 6544.0
Deduct 3960 from 4061 and we're left with 101.
Append the next digit (2) from the dividend to 101 and continue with: 1012 / 990

Going ahead to step 8:
990 goes into 1012 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 65441.0
Deduct 990 from 1012 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
990 goes into 220 0 times with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 65441.0
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
If we divide 2200 by 990, we get 2 and a remainder of 220.
Put 2 as the next digit of the answer. 
Result so far: 65441.02
If we subtract 1980 from 2200, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
990 can be fit into 2200 2 times, resulting in a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 65441.022
If we take 1980 away from 2200, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The quotient of the division is 65441.022, and the remainder is 0.022.
