We look at the division of 150486 by 49 
We want to figure out the number of times 150486 can be divided by 49.

On to step 1:
The number 49 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 49

On to step 2:
When dividing 15 by 49, we get 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 49

Going ahead to step 3:
49 can be fit into 150 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 3 after subtracting 147 from 150.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 49

Step 4:
49 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 34 after subtracting 0 from 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 49

Advancing to step 5:
348 divided by 49 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 307.0
The remainder is 5 after subtracting 343 from 348.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 49

On to step 6:
49 goes into 56 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 3071.0
Subtracting 49 from 56 leaves us 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 7:
When dividing 70 by 49, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 3071.1
If we subtract 49 from 70, we get 21.
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 8:
49 goes into 210 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 3071.14
Deduct 196 from 210 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
49 can be fit into 140 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 3071.142
Subtract 98 from 140 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
49 goes into 420 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 3071.1428
If we take 392 away from 420, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
49 goes into 280 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 3071.14285
The remainder is 35 after subtracting 245 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
If we divide 350 by 49, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 3071.142857
The remainder is 7 after subtracting 343 from 350.
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 13:
49 can be fit into 70 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 3071.1428571
Subtracting 49 from 70 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
49 goes into 210 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 3071.14285714
Subtracting 196 from 210 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 3071.14285714 with a remainder of 1.4e-08.
