125268 ÷ 51 
We want to figure out the number of times 125268 can be divided by 51.

Advancing to step 1:
The number 51 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 51

Going ahead to step 2:
If we divide 12 by 51, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 51

Let's proceed to step 3:
51 goes into 125 2 times with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 102 from 125, we get 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 51

Step 4:
51 can be fit into 232 4 times, resulting in a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 204 from 232, we get 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 51

Moving on to step 5:
When dividing 286 by 51, we get 5 with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
If we take 255 away from 286, we end up with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 51

Advancing to step 6:
318 divided by 51 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 2456.0
If we take 306 away from 318, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
51 goes into 120 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2456.2
If we subtract 102 from 120, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
The number 51 fits into 180 3 times, leaving a remainder of 27.
The next digit of our result is 3. 
Result so far: 2456.23
If we take 153 away from 180, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
If we divide 270 by 51, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 2456.235
The remainder is 15 after subtracting 255 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
150 divided by 51 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 2456.2352
The remainder is 48 after subtracting 102 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
When dividing 480 by 51, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 2456.23529
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
51 can be fit into 210 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 2456.235294
Subtracting 204 from 210 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
51 can be fit into 60 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 2456.2352941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
51 goes into 90 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 2456.23529411
Deduct 51 from 90 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 2456.23529411 with a remainder of 3.9e-08.
