We divide 630394 by 51
Our goal is to divide 630394 by 51.

Let's proceed to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 51

Let's proceed to step 2:
51 goes into 63 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 12 after subtracting 51 from 63.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 51

Advancing to step 3:
The number 51 fits into 120 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 102 from 120 to get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 51

Step 4:
51 goes into 183 3 times with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtract 153 from 183 to get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 51

Let's proceed to step 5:
51 goes into 309 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 1236.0
Subtracting 306 from 309 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 51

Going ahead to step 6:
51 goes into 34 0 times with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 12360.0
If we subtract 0 from 34, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
51 can be fit into 340 6 times, resulting in a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 12360.6
If we take 306 away from 340, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
340 divided by 51 is 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 12360.66
Subtract 306 from 340 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 12360.66 with a remainder of 0.034.
