We're dividing 48566930 by 86 
Let's see how many times 86 fits into 48566930.

Advancing 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
Subtracting 0 from 4 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 86

Advancing to step 2:
The number 86 fits into 48 0 times, leaving a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 86

Advancing to step 3:
485 divided by 86 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 430 from 485 leaves us with 55.
Bring next digit (6) of the dividend behind the 55 and repeat the process: 556 / 86

Step 4:
When dividing 556 by 86, we get 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtracting 516 from 556 leaves us with 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 86

Moving on to step 5:
406 divided by 86 is 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 564.0
Subtract 344 from 406 to get 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 86

On to step 6:
86 can be fit into 629 7 times, resulting in a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 5647.0
Subtracting 602 from 629 leaves us with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 86

Going ahead to step 7:
86 can be fit into 273 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 56473.0
Subtracting 258 from 273 leaves us with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 86

On to step 8:
86 goes into 150 1 times with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 564731.0
If we take 86 away from 150, we end up with 64.
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 9:
When dividing 640 by 86, we get 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 564731.7
Deduct 602 from 640 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.

Advancing to step 10:
380 divided by 86 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 564731.74
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 564731.744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 564731.744, and the remainder is 0.0016.
