302869 divided by 86 
We want to divide 302869 by 86.

On to step 1:
86 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 86

Moving on to step 2:
If we divide 30 by 86, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 86

Step 3:
When dividing 302 by 86, we get 3 with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 258 from 302 leaves us with 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 86

Moving on to step 4:
The number 86 fits into 448 5 times, leaving a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 430 from 448 to get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 86

On to step 5:
86 goes into 186 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 352.0
Deduct 172 from 186 and we're left with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 86

Let's proceed to step 6:
If we divide 149 by 86, we get 1 and a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 3521.0
Subtracting 86 from 149 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
630 divided by 86 is 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 3521.7
If we subtract 602 from 630, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
86 goes into 280 3 times with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 3521.73
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
220 divided by 86 is 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 3521.732
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
The number 86 fits into 480 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 3521.7325
If we take 430 away from 480, we end up 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.

Step 11:
If we divide 500 by 86, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 3521.73255
If we subtract 430 from 500, we get 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 final result is 3521.73255 with a remainder of 7e-05.
