We divide 678515 by 51
We want to divide 678515 by 51.

Advancing to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 51

On to step 2:
When dividing 67 by 51, we get 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 51 from 67 to get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 51

Advancing to step 3:
If we divide 168 by 51, we get 3 and a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 153 from 168 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 51

Advancing to step 4:
If we divide 155 by 51, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 133.0
Deduct 153 from 155 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 51

Advancing to step 5:
21 divided by 51 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 1330.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 51

Moving on to step 6:
215 divided by 51 is 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 13304.0
If we subtract 204 from 215, we get 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.
Record the quotient 2 as the next digit in the result. 
Result so far: 13304.2
Deduct 102 from 110 and we're left 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.

Let's proceed to step 8:
If we divide 80 by 51, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 13304.21
If we subtract 51 from 80, we get 29.
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:
If we divide 290 by 51, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 13304.215
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.

Step 10:
If we divide 350 by 51, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 13304.2156
If we subtract 306 from 350, we 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.

Moving on to step 11:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 13304.21568
Deduct 408 from 440 and we're left 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.

Let's proceed to step 12:
The number 51 fits into 320 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 13304.215686
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.

Step 13:
51 goes into 140 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 13304.2156862
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:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 13304.21568627
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 13304.21568627, with a leftover of 2.3e-08.
