We divide 303709 by 86
We're looking to find how many times 86 goes into 303709.

On to step 1:
3 divided by 86 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 86

Going ahead to step 2:
If we divide 30 by 86, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 86

Step 3:
If we divide 303 by 86, we get 3 and a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 258 from 303 to get 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 86

Let's proceed to step 4:
86 can be fit into 457 5 times, resulting in a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 430 away from 457, we end up with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 86

Going ahead to step 5:
270 divided by 86 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 353.0
Subtracting 258 from 270 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 86

Going ahead to step 6:
86 goes into 129 1 times with a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 3531.0
If we subtract 86 from 129, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
86 can be fit into 430 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3531.5
Deduct 430 from 430 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
86 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3531.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
86 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3531.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 3531.5, with a leftover of 0.0.
