We're dividing 486654 by 51 
Let's see how many times 51 fits into 486654.

Advancing to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 51

On to step 2:
51 can be fit into 48 0 times, resulting in a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 51

Going ahead to step 3:
If we divide 486 by 51, we get 9 and a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 27 after subtracting 459 from 486.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 51

Advancing to step 4:
276 divided by 51 is 5 with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Subtract 255 from 276 to get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 51

Going ahead to step 5:
51 goes into 215 4 times with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 954.0
Subtract 204 from 215 to get 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 51

Step 6:
When dividing 114 by 51, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 9542.0
Subtract 102 from 114 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 51, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 9542.2
Subtract 102 from 120 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
180 divided by 51 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 9542.23
If we take 153 away from 180, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
When dividing 270 by 51, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 9542.235
The remainder is 15 after subtracting 255 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
51 goes into 150 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 9542.2352
Subtracting 102 from 150 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
51 can be fit into 480 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 9542.23529
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
210 divided by 51 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 9542.235294
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
The number 51 fits into 60 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 9542.2352941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
51 goes into 90 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 9542.23529411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 9542.23529411 with a remaining 3.9e-08.
