We're dividing 668915 by 51 
Let's see how many times 51 fits into 668915.

Moving on to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 51

Let's proceed to step 2:
66 divided by 51 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 15 after subtracting 51 from 66.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 51

Going ahead to step 3:
If we divide 158 by 51, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 153 from 158 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 51

On to step 4:
51 goes into 59 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 131.0
If we take 51 away from 59, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 51

Step 5:
51 can be fit into 81 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1311.0
Deduct 51 from 81 and we're left with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 51

On to step 6:
The number 51 fits into 305 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 13115.0
If we subtract 255 from 305, we 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.

On to step 7:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 13115.9
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 8:
When dividing 410 by 51, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 13115.98
Subtracting 408 from 410 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
If we divide 20 by 51, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 13115.98
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
If we divide 200 by 51, we get 3 and a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 13115.9803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 11:
If we divide 470 by 51, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 13115.98039
Deduct 459 from 470 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
When dividing 110 by 51, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 13115.980392
Subtracting 102 from 110 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
The number 51 fits into 80 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 13115.9803921
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 14:
If we divide 290 by 51, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 13115.98039215
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 13115.98039215 with a remaining 3.5e-08.
