Let's divide 390380 by 85
Let's see how many times 85 fits into 390380.

Going ahead to step 1:
The number 85 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 85

Moving on to step 2:
If we divide 39 by 85, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 85

Step 3:
The number 85 fits into 390 4 times, leaving a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 340 from 390 to get 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 85

Advancing to step 4:
503 divided by 85 is 5 with a remainder of 78.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we take 425 away from 503, we end up with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 85

Moving on to step 5:
The number 85 fits into 788 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 459.0
If we subtract 765 from 788, we get 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 85

Step 6:
When dividing 230 by 85, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 4592.0
Subtract 170 from 230 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
600 divided by 85 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 4592.7
If we take 595 away from 600, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
50 divided by 85 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 4592.7
Subtracting 0 from 50 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:
85 goes into 500 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 4592.705
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 10:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 4592.7058
Subtract 680 from 750 to 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.

Moving on to step 11:
When dividing 700 by 85, we get 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 4592.70588
Subtracting 680 from 700 leaves us 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.

The quotient of the division is 4592.70588, and the remainder is 2e-05.
