We're dividing 341578 by 85 
Let's see how many times 85 fits into 341578.

On to step 1:
85 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 85

On to step 2:
85 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 85

On to step 3:
The number 85 fits into 341 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 1 after subtracting 340 from 341.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 85

Let's proceed to step 4:
15 divided by 85 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 85

Advancing to step 5:
157 divided by 85 is 1 with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 401.0
Deduct 85 from 157 and we're left with 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 85

Advancing to step 6:
85 can be fit into 728 8 times, resulting in a remainder of 48.
The next digit of our result is 8. 
Result so far: 4018.0
If we subtract 680 from 728, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
If we divide 480 by 85, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 4018.5
The remainder is 55 after subtracting 425 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 8:
When dividing 550 by 85, we get 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 4018.56
If we subtract 510 from 550, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
The number 85 fits into 400 4 times, leaving a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 4018.564
The remainder is 60 after subtracting 340 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
The number 85 fits into 600 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 4018.5647
Subtracting 595 from 600 leaves us 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 11:
If we divide 50 by 85, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4018.5647
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 4018.564705
If we take 425 away from 500, we end up 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.

Going ahead to step 13:
If we divide 750 by 85, we get 8 and a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 4018.5647058
Subtracting 680 from 750 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.

Let's proceed to step 14:
The number 85 fits into 700 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 4018.56470588
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 final result is 4018.56470588 with a remainder of 2e-08.
