Let's divide 15155 by 49
We're looking to find how many times 49 goes into 15155.

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

Going ahead to step 2:
49 can be fit into 15 0 times, resulting in 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.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 49

Going ahead to step 3:
If we divide 151 by 49, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
If we take 147 away from 151, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 49

On to step 4:
49 goes into 45 0 times with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 45 to get 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 49

Going ahead to step 5:
If we divide 455 by 49, we get 9 and a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 309.0
Subtracting 441 from 455 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.

Going ahead to step 6:
140 divided by 49 is 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 309.2
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.

On to step 7:
420 divided by 49 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 309.28
Subtract 392 from 420 to get 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 8:
49 goes into 280 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 309.285
If we take 245 away from 280, we end up with 35.
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 9:
If we divide 350 by 49, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 309.2857
Deduct 343 from 350 and we're left 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.

Step 10:
If we divide 70 by 49, we get 1 and a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 309.28571
Deduct 49 from 70 and we're left 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.

Advancing to step 11:
If we divide 210 by 49, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 309.285714
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 12:
140 divided by 49 is 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 309.2857142
Deduct 98 from 140 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
49 goes into 420 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 309.28571428
The remainder is 28 after subtracting 392 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 309.28571428 with a remainder of 2.8e-08.
