664395 divided by 51 
We want to divide 664395 by 51.

Advancing to step 1:
6 divided by 51 is 0 with 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

Moving on to step 2:
The number 51 fits into 66 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 15 after subtracting 51 from 66.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 51

Going ahead to step 3:
When dividing 154 by 51, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 153 from 154, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 51

Let's proceed to step 4:
13 divided by 51 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 130.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 51

Moving on to step 5:
If we divide 139 by 51, we get 2 and a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 1302.0
The remainder is 37 after subtracting 102 from 139.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 51

Advancing to step 6:
51 goes into 375 7 times with a remainder of 18.
The next digit of our result is 7. 
Result so far: 13027.0
If we subtract 357 from 375, we 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.

Advancing to step 7:
51 can be fit into 180 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 13027.3
Subtract 153 from 180 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
When dividing 270 by 51, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 13027.35
Subtracting 255 from 270 leaves us with 15.
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 9:
51 goes into 150 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 13027.352
The remainder is 48 after subtracting 102 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
51 can be fit into 480 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 13027.3529
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
When dividing 210 by 51, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 13027.35294
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
When dividing 60 by 51, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 13027.352941
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
51 can be fit into 90 1 times, resulting in a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 13027.3529411
If we subtract 51 from 90, we 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 13027.3529411 with a remaining 3.9e-07.
