667805 divided by 51 
We're looking to find how many times 51 goes into 667805.

On to step 1:
The number 51 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 51

On to step 2:
The number 51 fits into 66 1 times, leaving 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.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 51

Moving on to step 3:
If we divide 157 by 51, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 153 from 157, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 51

Going ahead to step 4:
When dividing 48 by 51, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 130.0
Subtracting 0 from 48 leaves us with 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 51

On to step 5:
51 goes into 480 9 times with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 1309.0
If we subtract 459 from 480, we get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 51

Advancing to step 6:
The number 51 fits into 215 4 times, leaving a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 13094.0
If we take 204 away from 215, we end up 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.

Step 7:
When dividing 110 by 51, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 13094.2
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
51 can be fit into 80 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 13094.21
The remainder is 29 after subtracting 51 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
51 goes into 290 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 13094.215
Subtract 255 from 290 to 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.

Step 10:
If we divide 350 by 51, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 13094.2156
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 11:
When dividing 440 by 51, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 13094.21568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
51 can be fit into 320 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 13094.215686
The remainder is 14 after subtracting 306 from 320.
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 13:
When dividing 140 by 51, we get 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 13094.2156862
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.

Step 14:
When dividing 380 by 51, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 13094.21568627
Subtract 357 from 380 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 13094.21568627, with a leftover of 2.3e-08.
