64845402 divided by 990 
We want to figure out the number of times 64845402 can be divided by 990.

Let's proceed to step 1:
6 divided by 990 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 990

On to step 2:
990 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 990

Step 3:
648 divided by 990 is 0 with a remainder of 648.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 648 to get 648.
Append the next digit (4) from the dividend to 648 and continue with: 6484 / 990

Advancing to step 4:
990 goes into 6484 6 times with a remainder of 544.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 5940 away from 6484, we end up with 544.
Fetch the next digit (5) from the dividend, attach it to 544 and continue: 5445 / 990

Going ahead to step 5:
990 can be fit into 5445 5 times, resulting in a remainder of 495.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 4950 from 5445 to get 495.
Bring next digit (4) of the dividend behind the 495 and repeat the process: 4954 / 990

Going ahead to step 6:
990 goes into 4954 5 times with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 655.0
Deduct 4950 from 4954 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 990

On to step 7:
990 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6550.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 990

Advancing to step 8:
402 divided by 990 is 0 with a remainder of 402.
The next digit of our result is 0. 
Result so far: 65500.0
Subtract 0 from 402 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 9:
If we divide 4020 by 990, we get 4 and a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 65500.4
The remainder is 60 after subtracting 3960 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
When dividing 600 by 990, we get 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 65500.4
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 11:
The number 990 fits into 6000 6 times, leaving a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 65500.406
Deduct 5940 from 6000 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
When dividing 600 by 990, we get 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 65500.406
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 13:
The number 990 fits into 6000 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 65500.40606
Subtracting 5940 from 6000 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
990 can be fit into 600 0 times, resulting in a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 65500.40606
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 15:
6000 divided by 990 is 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 65500.4060606
Subtract 5940 from 6000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
The number 990 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 65500.4060606
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 65500.4060606 with a remainder of 6e-07.
