We look at the division of 515548 by 49 
We want to figure out the number of times 515548 can be divided by 49.

Moving on to step 1:
5 divided by 49 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 49

Going ahead to step 2:
49 goes into 51 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 49 away from 51, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 49

Advancing to step 3:
When dividing 25 by 49, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 49

Advancing to step 4:
If we divide 255 by 49, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtract 245 from 255 to get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 49

On to step 5:
If we divide 104 by 49, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 1052.0
Deduct 98 from 104 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 49

On to step 6:
49 goes into 68 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 10521.0
If we take 49 away from 68, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 49, we get 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 10521.3
Subtracting 147 from 190 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.

On to step 8:
When dividing 430 by 49, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 10521.38
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.

Moving on to step 9:
If we divide 380 by 49, we get 7 and a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 10521.387
If we take 343 away from 380, we end up 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.

Going ahead to step 10:
49 can be fit into 370 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 10521.3877
The remainder is 27 after subtracting 343 from 370.
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 10521.3877 with a remaining 0.00027.
