We look at the division of 51278927 by 149 
Our goal is to divide 51278927 by 149.

Step 1:
If we divide 5 by 149, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 149

Advancing to step 2:
The number 149 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 149

Advancing to step 3:
149 goes into 512 3 times with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 447 from 512 and we're left with 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 149

On to step 4:
The number 149 fits into 657 4 times, leaving a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 596 from 657, we get 61.
Include the next digit (8) from the dividend after 61, then repeat: 618 / 149

Moving on to step 5:
When dividing 618 by 149, we get 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 344.0
Subtract 596 from 618 to get 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 149

Step 6:
149 can be fit into 229 1 times, resulting in a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 3441.0
The remainder is 80 after subtracting 149 from 229.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 149

Going ahead to step 7:
If we divide 802 by 149, we get 5 and a remainder of 57.
Record the quotient 5 as the next digit in the result. 
Result so far: 34415.0
Subtracting 745 from 802 leaves us with 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 149

Let's proceed to step 8:
If we divide 577 by 149, we get 3 and a remainder of 130.
The next digit of our result is 3. 
Result so far: 344153.0
The remainder is 130 after subtracting 447 from 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 9:
149 can be fit into 1300 8 times, resulting in a remainder of 108.
Put 8 as the next digit of the answer. 
Result so far: 344153.8
Subtracting 1192 from 1300 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 10:
When dividing 1080 by 149, we get 7 with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 344153.87
Subtracting 1043 from 1080 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.

Step 11:
149 goes into 370 2 times with a remainder of 72.
The next digit of our result is 2. 
Result so far: 344153.872
If we take 298 away from 370, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
When dividing 720 by 149, we get 4 with a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 344153.8724
If we take 596 away from 720, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 13:
149 goes into 1240 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 344153.87248
The remainder is 48 after subtracting 1192 from 1240.
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 14:
149 goes into 480 3 times with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 344153.872483
If we take 447 away from 480, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 15:
If we divide 330 by 149, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 344153.8724832
Subtracting 298 from 330 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 16:
The number 149 fits into 320 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 344153.87248322
Deduct 298 from 320 and we're left 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.

In conclusion, the division gives 344153.87248322 with a balance of 2.2e-08.
