644948 divided by 66 
Our goal is to divide 644948 by 66.

Let's proceed to step 1:
66 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 66

Step 2:
The number 66 fits into 64 0 times, leaving a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 66

Advancing to step 3:
644 divided by 66 is 9 with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 50 after subtracting 594 from 644.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 66

On to step 4:
If we divide 509 by 66, we get 7 and a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 97.0
If we take 462 away from 509, we end up with 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 66

Advancing to step 5:
When dividing 474 by 66, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 977.0
Subtracting 462 from 474 leaves us with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 66

Let's proceed to step 6:
When dividing 128 by 66, we get 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 9771.0
Subtract 66 from 128 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
66 goes into 620 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 9771.9
If we subtract 594 from 620, 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.

Going ahead to step 8:
260 divided by 66 is 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 9771.93
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
If we divide 620 by 66, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 9771.939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
The number 66 fits into 260 3 times, leaving a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 9771.9393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
If we divide 620 by 66, we get 9 and a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 9771.93939
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 9771.939393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
66 goes into 620 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 9771.9393939
If we subtract 594 from 620, 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.

Let's proceed to step 14:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 9771.93939393
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 9771.93939393, and the remainder is 6.2e-08.
