149272 ÷ 51 
Let's see how many times 51 fits into 149272.

Step 1:
When dividing 1 by 51, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 51

Moving on to step 2:
When dividing 14 by 51, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 51

Moving on to step 3:
If we divide 149 by 51, we get 2 and a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 47 after subtracting 102 from 149.
Bring next digit (2) of the dividend behind the 47 and repeat the process: 472 / 51

Step 4:
472 divided by 51 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 13 after subtracting 459 from 472.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 51

Advancing to step 5:
51 goes into 137 2 times with a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 292.0
If we take 102 away from 137, we end up with 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 51

On to step 6:
352 divided by 51 is 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 2926.0
If we subtract 306 from 352, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 2926.9
If we take 459 away from 460, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
The number 51 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2926.9
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 51, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 2926.901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 10:
490 divided by 51 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 2926.9019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
51 goes into 310 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2926.90196
If we take 306 away from 310, we end up 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.

Step 12:
When dividing 40 by 51, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2926.90196
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.

On to step 13:
If we divide 400 by 51, we get 7 and a remainder of 43.
The next digit of our result is 7. 
Result so far: 2926.9019607
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 14:
The number 51 fits into 430 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 2926.90196078
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.

After the division, we end up with 2926.90196078 and a remainder of 2.2e-08.
