309004 divided by 51 
Our goal is to divide 309004 by 51.

Step 1:
3 divided by 51 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 51

Advancing to step 2:
If we divide 30 by 51, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 51

Let's proceed to step 3:
51 goes into 309 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 3 after subtracting 306 from 309.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 51

Going ahead to step 4:
If we divide 30 by 51, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 60.0
If we take 0 away from 30, we end up with 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 51

Let's proceed to step 5:
When dividing 300 by 51, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 605.0
If we take 255 away from 300, we end up with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 51

On to step 6:
51 can be fit into 454 8 times, resulting in a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 6058.0
Deduct 408 from 454 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 6058.9
Subtracting 459 from 460 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
The number 51 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 6058.9
Subtracting 0 from 10 leaves us 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.

Going ahead to step 9:
51 goes into 100 1 times with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 6058.901
If we take 51 away from 100, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
51 can be fit into 490 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 6058.9019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 11:
51 goes into 310 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 6058.90196
Subtract 306 from 310 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
The number 51 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6058.90196
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
51 can be fit into 400 7 times, resulting in a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 6058.9019607
Deduct 357 from 400 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 14:
430 divided by 51 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 6058.90196078
The remainder is 22 after subtracting 408 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 6058.90196078 with a remainder of 2.2e-08.
