630429 ÷ 66 
Our goal is to divide 630429 by 66.

Step 1:
If we divide 6 by 66, we get 0 and 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.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 66

Moving on to step 2:
66 goes into 63 0 times with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 66

Moving on to step 3:
When dividing 630 by 66, we get 9 with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 594 from 630 leaves us with 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 66

Let's proceed to step 4:
When dividing 364 by 66, we get 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtracting 330 from 364 leaves us with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 66

Advancing to step 5:
66 can be fit into 342 5 times, resulting in a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 955.0
If we subtract 330 from 342, we get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 66

Advancing to step 6:
When dividing 129 by 66, we get 1 with a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 9551.0
If we take 66 away from 129, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
The number 66 fits into 630 9 times, leaving a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 9551.9
The remainder is 36 after subtracting 594 from 630.
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 8:
360 divided by 66 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 9551.95
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.

Moving on to step 9:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 9551.954
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.

On to step 10:
360 divided by 66 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 9551.9545
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 11:
300 divided by 66 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 9551.95454
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.

Let's proceed to step 12:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 9551.954545
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 13:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 9551.9545454
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.

Advancing to step 14:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9551.95454545
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.

The quotient of the division is 9551.95454545, and the remainder is 3e-08.
