We're dividing 309426 by 85 
Our goal is to divide 309426 by 85.

Advancing to step 1:
3 divided by 85 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 85

On to step 2:
When dividing 30 by 85, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 85

Let's proceed to step 3:
When dividing 309 by 85, we get 3 with a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 255 from 309 to get 54.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 85

Going ahead to step 4:
If we divide 544 by 85, we get 6 and a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtract 510 from 544 to get 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 85

Step 5:
342 divided by 85 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 364.0
Subtract 340 from 342 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 85

Step 6:
When dividing 26 by 85, we get 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 3640.0
The remainder is 26 after subtracting 0 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
The number 85 fits into 260 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3640.3
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
85 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 3640.3
Deduct 0 from 50 and we're left 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.

On to step 9:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 3640.305
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 10:
750 divided by 85 is 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 3640.3058
Deduct 680 from 750 and we're left 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.

Going ahead to step 11:
The number 85 fits into 700 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 3640.30588
The remainder is 20 after subtracting 680 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 3640.30588 with a remaining 2e-05.
