353631 divided by 66 
Let's see how many times 66 fits into 353631.

Let's proceed to step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 66

Advancing to step 2:
35 divided by 66 is 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 66

Let's proceed to step 3:
66 goes into 353 5 times with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 330 from 353 to get 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 66

Let's proceed to step 4:
236 divided by 66 is 3 with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we take 198 away from 236, we end up with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 66

Let's proceed to step 5:
66 can be fit into 383 5 times, resulting in a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 535.0
Subtracting 330 from 383 leaves us with 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 66

Going ahead to step 6:
If we divide 531 by 66, we get 8 and a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 5358.0
If we subtract 528 from 531, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 66 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 5358.0
Subtracting 0 from 30 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.

Moving on to step 8:
If we divide 300 by 66, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 5358.04
Deduct 264 from 300 and we're left 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.

Moving on to step 9:
When dividing 360 by 66, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 5358.045
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.

Moving on to step 10:
When dividing 300 by 66, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 5358.0454
Deduct 264 from 300 and we're left 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.

On to step 11:
66 goes into 360 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5358.04545
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.

Step 12:
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: 5358.045454
If we take 264 away from 300, we end up 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.

On to step 13:
66 can be fit into 360 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5358.0454545
If we take 330 away from 360, we end up 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.

On to step 14:
66 goes into 300 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 5358.04545454
If we take 264 away from 300, we end up 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.

After the division, we end up with 5358.04545454 and a remainder of 3.6e-08.
