We're dividing 654409 by 51 
We're looking to find how many times 51 goes into 654409.

Moving on to step 1:
The number 51 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 51

Advancing to step 2:
When dividing 65 by 51, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 65 to get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 51

On to step 3:
51 goes into 144 2 times with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 102 from 144 leaves us with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 51

Step 4:
If we divide 424 by 51, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
If we subtract 408 from 424, we get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 51

Going ahead to step 5:
When dividing 160 by 51, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 1283.0
Deduct 153 from 160 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 51

Going ahead to step 6:
The number 51 fits into 79 1 times, leaving a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 12831.0
If we subtract 51 from 79, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
51 goes into 280 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 12831.5
Subtract 255 from 280 to 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.

Let's proceed to step 8:
If we divide 250 by 51, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 12831.54
If we subtract 204 from 250, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
When dividing 460 by 51, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 12831.549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
51 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 12831.549
Deduct 0 from 10 and we're left 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 11:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 12831.54901
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.

Moving on to step 12:
If we divide 490 by 51, we get 9 and a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 12831.549019
Subtract 459 from 490 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
If we divide 310 by 51, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 12831.5490196
Subtracting 306 from 310 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
51 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12831.5490196
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.

After the division, we end up with 12831.5490196 and a remainder of 4e-08.
