We're dividing 302699 by 86 
We want to figure out the number of times 302699 can be divided by 86.

Advancing to step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 86

Going ahead to step 2:
If we divide 30 by 86, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 86

On to step 3:
If we divide 302 by 86, we get 3 and a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 258 from 302 leaves us with 44.
Bring next digit (6) of the dividend behind the 44 and repeat the process: 446 / 86

Step 4:
86 goes into 446 5 times with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 16 after subtracting 430 from 446.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 86

Moving on to step 5:
The number 86 fits into 169 1 times, leaving a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 351.0
Subtracting 86 from 169 leaves us with 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 86

On to step 6:
The number 86 fits into 839 9 times, leaving a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 3519.0
The remainder is 65 after subtracting 774 from 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
86 can be fit into 650 7 times, resulting in a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 3519.7
The remainder is 48 after subtracting 602 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
When dividing 480 by 86, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3519.75
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
500 divided by 86 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 3519.755
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 3519.755, and the remainder is 0.007.
