We're dividing 630262 by 51 
We want to figure out the number of times 630262 can be divided by 51.

Step 1:
51 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 51

Moving on to step 2:
63 divided by 51 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 51 from 63 and we're left with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 51

On to step 3:
If we divide 120 by 51, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 102 from 120 to get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 51

On to step 4:
51 goes into 182 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
If we take 153 away from 182, we end up with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 51

Moving on to step 5:
296 divided by 51 is 5 with a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 1235.0
Subtract 255 from 296 to get 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 51

Going ahead to step 6:
51 goes into 412 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 12358.0
Deduct 408 from 412 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
51 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 12358.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
51 goes into 400 7 times with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 12358.07
If we take 357 away from 400, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
430 divided by 51 is 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 12358.078
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
51 can be fit into 220 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 12358.0784
The remainder is 16 after subtracting 204 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 12358.07843
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
51 can be fit into 70 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 12358.078431
If we subtract 51 from 70, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
When dividing 190 by 51, we get 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 12358.0784313
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 14:
When dividing 370 by 51, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 12358.07843137
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 12358.07843137, with a leftover of 1.3e-08.
