320389 divided by 85 
Let's see how many times 85 fits into 320389.

Let's proceed to step 1:
85 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 85

Going ahead to step 2:
The number 85 fits into 32 0 times, leaving a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 85

Moving on to step 3:
85 goes into 320 3 times with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 65 after subtracting 255 from 320.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 85

On to step 4:
The number 85 fits into 653 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 595 from 653 and we're left with 58.
Fetch the next digit (8) from the dividend, attach it to 58 and continue: 588 / 85

Moving on to step 5:
85 goes into 588 6 times with a remainder of 78.
The next digit of our result is 6. 
Result so far: 376.0
Subtracting 510 from 588 leaves us with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 85

Let's proceed to step 6:
If we divide 789 by 85, we get 9 and a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 3769.0
Deduct 765 from 789 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
85 can be fit into 240 2 times, resulting in a remainder of 70.
Put 2 as the next digit of the answer. 
Result so far: 3769.2
If we subtract 170 from 240, 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.

On to step 8:
When dividing 700 by 85, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 3769.28
Deduct 680 from 700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
85 goes into 200 2 times with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 3769.282
Deduct 170 from 200 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
If we divide 300 by 85, we get 3 and a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 3769.2823
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
When dividing 450 by 85, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 3769.28235
Subtracting 425 from 450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
When dividing 250 by 85, we get 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 3769.282352
Subtract 170 from 250 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
85 can be fit into 800 9 times, resulting in a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 3769.2823529
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
85 can be fit into 350 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 3769.28235294
Deduct 340 from 350 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 3769.28235294 and a remainder of 1e-08.
