28451965 divided by 66 
We want to figure out the number of times 28451965 can be divided by 66.

Going ahead to step 1:
When dividing 2 by 66, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 66

Going ahead to step 2:
66 goes into 28 0 times with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 66

On to step 3:
If we divide 284 by 66, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 264 from 284 and we're left with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 66

Let's proceed to step 4:
The number 66 fits into 205 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtract 198 from 205 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 66

Step 5:
66 can be fit into 71 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 431.0
The remainder is 5 after subtracting 66 from 71.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 66

Let's proceed to step 6:
66 goes into 59 0 times with a remainder of 59.
The next digit of our result is 0. 
Result so far: 4310.0
Subtract 0 from 59 to get 59.
Include the next digit (6) from the dividend after 59, then repeat: 596 / 66

On to step 7:
The number 66 fits into 596 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 43109.0
Subtract 594 from 596 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 66

Moving on to step 8:
66 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 431090.0
Subtract 0 from 25 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
When dividing 250 by 66, we get 3 with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 431090.3
Subtracting 198 from 250 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
66 goes into 520 7 times with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 431090.37
If we subtract 462 from 520, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 11:
When dividing 580 by 66, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 431090.378
The remainder is 52 after subtracting 528 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
The number 66 fits into 520 7 times, leaving a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 431090.3787
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
When dividing 580 by 66, we get 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 431090.37878
Subtracting 528 from 580 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
66 can be fit into 520 7 times, resulting in a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 431090.378787
Deduct 462 from 520 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 15:
580 divided by 66 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 431090.3787878
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 16:
66 goes into 520 7 times with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 431090.37878787
If we take 462 away from 520, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 431090.37878787 and a remainder of 5.8e-08.
