We're dividing 363459 by 86 
We're looking to find how many times 86 goes into 363459.

Step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 86

Advancing to step 2:
86 goes into 36 0 times with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 86

Step 3:
If we divide 363 by 86, we get 4 and a remainder of 19.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 344 from 363, we get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 86

Moving on to step 4:
The number 86 fits into 194 2 times, leaving a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 172 from 194 and we're left with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 86

On to step 5:
When dividing 225 by 86, we get 2 with a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 422.0
If we subtract 172 from 225, we get 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 86

Advancing to step 6:
If we divide 539 by 86, we get 6 and a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 4226.0
The remainder is 23 after subtracting 516 from 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
When dividing 230 by 86, we get 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 4226.2
If we subtract 172 from 230, 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 8:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 4226.26
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.

On to step 9:
If we divide 640 by 86, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 4226.267
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.

Moving on 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: 4226.2674
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.

Moving on to step 11:
If we divide 360 by 86, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 4226.26744
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.

Our division results in 4226.26744 with a remaining 1.6e-05.
