We look at the division of 363666 by 85 
We want to divide 363666 by 85.

Step 1:
85 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 85

Advancing to step 2:
85 can be fit into 36 0 times, resulting in a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 85

Advancing to step 3:
85 goes into 363 4 times with a remainder of 23.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 340 from 363, we get 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 85

Let's proceed to step 4:
85 can be fit into 236 2 times, resulting in a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 170 away from 236, we end up with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 85

Advancing to step 5:
If we divide 666 by 85, we get 7 and a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 427.0
Deduct 595 from 666 and we're left with 71.
Fetch the next digit (6) from the dividend, attach it to 71 and continue: 716 / 85

On to step 6:
85 can be fit into 716 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 4278.0
Deduct 680 from 716 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
85 can be fit into 360 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 4278.4
Deduct 340 from 360 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.

Moving on to step 8:
85 goes into 200 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 4278.42
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.

Going ahead to step 9:
The number 85 fits into 300 3 times, leaving a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 4278.423
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
When dividing 450 by 85, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4278.4235
If we subtract 425 from 450, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
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: 4278.42352
Deduct 170 from 250 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
If we divide 800 by 85, we get 9 and a remainder of 35.
The next digit of our result is 9. 
Result so far: 4278.423529
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.

Going ahead to step 13:
If we divide 350 by 85, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4278.4235294
If we take 340 away from 350, we end up 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.

Advancing to step 14:
When dividing 100 by 85, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 4278.42352941
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 4278.42352941 and a remainder of 1.5e-08.
