If we divide 33 by 394, we get 0 and a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 394

Let's proceed to step 3:
330 divided by 394 is 0 with a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 330 to get 330.
Include the next digit (8) from the dividend after 330, then repeat: 3308 / 394

Advancing to step 4:
If we divide 3308 by 394, we get 8 and a remainder of 156.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 3152 from 3308 and we're left with 156.
Fetch the next digit (6) from the dividend, attach it to 156 and continue: 1566 / 394

Going ahead to step 5:
When dividing 1566 by 394, we get 3 with a remainder of 384.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Subtracting 1182 from 1566 leaves us with 384.
Fetch the next digit (6) from the dividend, attach it to 384 and continue: 3846 / 394

Going ahead to step 6:
The number 394 fits into 3846 9 times, leaving a remainder of 300.
Record the quotient 9 as the next digit in the result. 
Result so far: 839.0
If we take 3546 away from 3846, we end up with 300.
Append the next digit (6) from the dividend to 300 and continue with: 3006 / 394

On to step 7:
If we divide 3006 by 394, we get 7 and a remainder of 248.
Use 7 as the next digit of our solution. 
Result so far: 8397.0
Subtract 2758 from 3006 to get 248.
Fetch the next digit (4) from the dividend, attach it to 248 and continue: 2484 / 394

Moving on to step 8:
2484 divided by 394 is 6 with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 83976.0
Subtract 2364 from 2484 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 9:
394 goes into 1200 3 times with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 83976.3
Subtracting 1182 from 1200 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
If we divide 180 by 394, we get 0 and a remainder of 180.
The next digit of our result is 0. 
Result so far: 83976.3
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
The number 394 fits into 1800 4 times, leaving a remainder of 224.
The next digit of our result is 4. 
Result so far: 83976.304
If we take 1576 away from 1800, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 12:
2240 divided by 394 is 5 with a remainder of 270.
The next digit of our result is 5. 
Result so far: 83976.3045
If we subtract 1970 from 2240, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 13:
If we divide 2700 by 394, we get 6 and a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 83976.30456
The remainder is 336 after subtracting 2364 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 14:
When dividing 3360 by 394, we get 8 with a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 83976.304568
If we subtract 3152 from 3360, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 15:
The number 394 fits into 2080 5 times, leaving a remainder of 110.
The next digit of our result is 5. 
Result so far: 83976.3045685
If we subtract 1970 from 2080, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 16:
394 goes into 1100 2 times with a remainder of 312.
The next digit of our result is 2. 
Result so far: 83976.30456852
Subtract 788 from 1100 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Our division results in 83976.30456852 with a remaining 3.12e-07.
