641187 ÷ 66 
Our goal is to divide 641187 by 66.

Moving on to step 1:
6 divided by 66 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 66

Going ahead to step 2:
If we divide 64 by 66, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 66

Step 3:
The number 66 fits into 641 9 times, leaving a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 594 from 641 leaves us with 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 66

On to step 4:
66 can be fit into 471 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we subtract 462 from 471, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 66

Let's proceed to step 5:
66 goes into 98 1 times with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 971.0
Subtracting 66 from 98 leaves us with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 66

Going ahead to step 6:
When dividing 327 by 66, we get 4 with a remainder of 63.
Write down 4 as next digit of the result. 
Result so far: 9714.0
Subtract 264 from 327 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
630 divided by 66 is 9 with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 9714.9
Subtracting 594 from 630 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9714.95
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
When dividing 300 by 66, we get 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 9714.954
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
If we divide 360 by 66, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9714.9545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
If we divide 300 by 66, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 9714.95454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
66 can be fit into 360 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 9714.954545
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 9714.9545454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9714.95454545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 9714.95454545 with a remaining 3e-08.
