Let's divide 309074 by 54
We want to divide 309074 by 54.

Going ahead to step 1:
If we divide 3 by 54, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 54

Moving on to step 2:
54 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 54

On to step 3:
54 goes into 309 5 times with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 270 away from 309, we end up with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 54

Step 4:
If we divide 390 by 54, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 57.0
Deduct 378 from 390 and we're left with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 54

Going ahead to step 5:
127 divided by 54 is 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 572.0
If we subtract 108 from 127, we get 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 54

On to step 6:
194 divided by 54 is 3 with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 5723.0
Subtracting 162 from 194 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
320 divided by 54 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 5723.5
The remainder is 50 after subtracting 270 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
500 divided by 54 is 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 5723.59
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
140 divided by 54 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 5723.592
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
The number 54 fits into 320 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5723.5925
Subtract 270 from 320 to 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.

Moving on to step 11:
The number 54 fits into 500 9 times, leaving a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 5723.59259
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
If we divide 140 by 54, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 5723.592592
Subtracting 108 from 140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
320 divided by 54 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 5723.5925925
Deduct 270 from 320 and we're left 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.

Advancing to step 14:
54 goes into 500 9 times with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 5723.59259259
If we subtract 486 from 500, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 5723.59259259 with a remainder of 1.4e-08.
