4249 divided by 86 
Let's see how many times 86 fits into 4249.

Step 1:
If we divide 4 by 86, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 86

Moving on to step 2:
When dividing 42 by 86, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 86

On to step 3:
The number 86 fits into 424 4 times, leaving a remainder of 80.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 80 after subtracting 344 from 424.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 86

Step 4:
86 goes into 809 9 times with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 774 from 809, we 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.

Step 5:
86 goes into 350 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 49.4
If we take 344 away from 350, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 6:
When dividing 60 by 86, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 49.4
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
When dividing 600 by 86, we get 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 49.406
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 8:
If we divide 840 by 86, we get 9 and a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 49.4069
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
86 goes into 660 7 times with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 49.40697
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
86 can be fit into 580 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 49.406976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
86 goes into 640 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 49.4069767
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 49.40697674
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 49.40697674 with a balance of 3.6e-08.
