We divide 664661 by 51
We want to divide 664661 by 51.

On to step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 51

Let's proceed to step 2:
If we divide 66 by 51, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 51 from 66 leaves us with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 51

Step 3:
51 goes into 154 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 153 from 154 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 51

On to step 4:
When dividing 16 by 51, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
If we take 0 away from 16, we end up with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 51

On to step 5:
When dividing 166 by 51, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 1303.0
If we subtract 153 from 166, we get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 51

Going ahead to step 6:
131 divided by 51 is 2 with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 13032.0
The remainder is 29 after subtracting 102 from 131.
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 7:
51 goes into 290 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 13032.5
If we take 255 away from 290, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 13032.56
Subtract 306 from 350 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
If we divide 440 by 51, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 13032.568
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
51 can be fit into 320 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 13032.5686
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
140 divided by 51 is 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 13032.56862
Subtracting 102 from 140 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
If we divide 380 by 51, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 13032.568627
Deduct 357 from 380 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
When dividing 230 by 51, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 13032.5686274
If we take 204 away from 230, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 13032.56862745
If we subtract 255 from 260, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 13032.56862745 and a remainder of 5e-09.
