We look at the division of 503655 by 86 
We're looking to find how many times 86 goes into 503655.

Step 1:
The number 86 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 86

On to step 2:
When dividing 50 by 86, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 86

Step 3:
86 goes into 503 5 times with a remainder of 73.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 430 from 503 to get 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 86

Step 4:
If we divide 736 by 86, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 688 from 736 leaves us with 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 86

Advancing to step 5:
The number 86 fits into 485 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 585.0
The remainder is 55 after subtracting 430 from 485.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 86

Advancing to step 6:
If we divide 555 by 86, we get 6 and a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 5856.0
Deduct 516 from 555 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
390 divided by 86 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 5856.4
Subtracting 344 from 390 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.

Going ahead to step 8:
The number 86 fits into 460 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5856.45
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
When dividing 300 by 86, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 5856.453
Deduct 258 from 300 and we're left with 42.
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 10:
When dividing 420 by 86, we get 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 5856.4534
Deduct 344 from 420 and we're left with 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 11:
If we divide 760 by 86, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 5856.45348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
86 can be fit into 720 8 times, resulting in a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5856.453488
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.

Our division results in 5856.453488 with a remaining 3.2e-06.
