We're dividing 636260 by 51 
We're looking to find how many times 51 goes into 636260.

On to step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 51

Moving on to step 2:
The number 51 fits into 63 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 51 from 63 to get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 51

Step 3:
If we divide 126 by 51, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 102 from 126 leaves us with 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 51

Going ahead to step 4:
When dividing 242 by 51, we get 4 with a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtract 204 from 242 to get 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 51

Going ahead to step 5:
When dividing 386 by 51, we get 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 1247.0
Deduct 357 from 386 and we're left with 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 51

Going ahead to step 6:
51 goes into 290 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 12475.0
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
51 goes into 350 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 12475.6
Deduct 306 from 350 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
If we divide 440 by 51, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 12475.68
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 51, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 12475.686
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
51 can be fit into 140 2 times, resulting in a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 12475.6862
If we subtract 102 from 140, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
The number 51 fits into 380 7 times, leaving a remainder of 23.
The next digit of our result is 7. 
Result so far: 12475.68627
If we take 357 away from 380, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
51 can be fit into 230 4 times, resulting in a remainder of 26.
The next digit of our result is 4. 
Result so far: 12475.686274
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
260 divided by 51 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12475.6862745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
51 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 12475.6862745
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 12475.6862745 and a remainder of 5e-08.
