158509 ÷ 49 
We're looking to find how many times 49 goes into 158509.

Going ahead to step 1:
1 divided by 49 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 49

Moving on to step 2:
When dividing 15 by 49, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 49

Moving on to step 3:
158 divided by 49 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 147 from 158, we get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 49

On to step 4:
The number 49 fits into 115 2 times, leaving a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we take 98 away from 115, we end up with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 49

Step 5:
49 goes into 170 3 times with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 323.0
Subtracting 147 from 170 leaves us with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 49

On to step 6:
239 divided by 49 is 4 with a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 3234.0
Subtracting 196 from 239 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
The number 49 fits into 430 8 times, leaving a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 3234.8
Deduct 392 from 430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
380 divided by 49 is 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 3234.87
Subtract 343 from 380 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
370 divided by 49 is 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 3234.877
Subtract 343 from 370 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 3234.877 with a remaining 0.0027.
