305054 ÷ 86 
We want to divide 305054 by 86.

Moving on to step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 86

On to step 2:
86 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 86

Going ahead to step 3:
86 can be fit into 305 3 times, resulting in a remainder of 47.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 258 from 305 to get 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 86

Advancing to step 4:
86 goes into 470 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 430 from 470 and we're left with 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 86

Let's proceed to step 5:
86 can be fit into 405 4 times, resulting in a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 354.0
Deduct 344 from 405 and we're left with 61.
Take the next digit (4) from the dividend and append it to 61, then repeat: 614 / 86

Let's proceed to step 6:
If we divide 614 by 86, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 3547.0
If we take 602 away from 614, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 86, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 3547.1
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
86 goes into 340 3 times with a remainder of 82.
The next digit of our result is 3. 
Result so far: 3547.13
The remainder is 82 after subtracting 258 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 9:
86 goes into 820 9 times with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 3547.139
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
If we divide 460 by 86, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3547.1395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
If we divide 300 by 86, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 3547.13953
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
86 goes into 420 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 3547.139534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
When dividing 760 by 86, we get 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 3547.1395348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
The number 86 fits into 720 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 3547.13953488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 3547.13953488, with a leftover of 3.2e-08.
