81578 divided by 49 
We want to figure out the number of times 81578 can be divided by 49.

Going ahead to step 1:
The number 49 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 49

Moving on to step 2:
49 can be fit into 81 1 times, resulting in a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 49 from 81 to get 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 49

Advancing to step 3:
325 divided by 49 is 6 with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 294 from 325 leaves us with 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 49

Let's proceed to step 4:
The number 49 fits into 317 6 times, leaving a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 166.0
Subtracting 294 from 317 leaves us with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 49

Moving on to step 5:
The number 49 fits into 238 4 times, leaving a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 1664.0
Subtracting 196 from 238 leaves us 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.

Going ahead to step 6:
420 divided by 49 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 1664.8
Subtracting 392 from 420 leaves us 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 7:
When dividing 280 by 49, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1664.85
Subtract 245 from 280 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
If we divide 350 by 49, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 1664.857
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.

On to step 9:
49 goes into 70 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1664.8571
Subtract 49 from 70 to 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.

On to step 10:
The number 49 fits into 210 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 1664.85714
The remainder is 14 after subtracting 196 from 210.
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 11:
If we divide 140 by 49, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 1664.857142
If we subtract 98 from 140, we 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.

Step 12:
The number 49 fits into 420 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 1664.8571428
If we subtract 392 from 420, we 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.

Moving on to step 13:
280 divided by 49 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 1664.85714285
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.

After the division, we end up with 1664.85714285 and a remainder of 3.5e-08.
