49949 divided by 86 
Let's see how many times 86 fits into 49949.

On to step 1:
86 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 86

Moving on to step 2:
86 can be fit into 49 0 times, resulting in a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 86

On to step 3:
When dividing 499 by 86, we get 5 with a remainder of 69.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 69 after subtracting 430 from 499.
Bring next digit (4) of the dividend behind the 69 and repeat the process: 694 / 86

Advancing to step 4:
694 divided by 86 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 58.0
If we subtract 688 from 694, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 86

Step 5:
86 can be fit into 69 0 times, resulting in a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 580.0
If we take 0 away from 69, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 6:
The number 86 fits into 690 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 580.8
Subtract 688 from 690 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 580.8
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
86 can be fit into 200 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 580.802
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
86 can be fit into 280 3 times, resulting in a remainder of 22.
The next digit of our result is 3. 
Result so far: 580.8023
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
220 divided by 86 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 580.80232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
When dividing 480 by 86, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 580.802325
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
If we divide 500 by 86, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 580.8023255
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 580.8023255 and a remainder of 7e-07.
