We divide 680243 by 51
Let's see how many times 51 fits into 680243.

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.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 51

Step 2:
51 can be fit into 68 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 51 from 68, we get 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 51

Step 3:
51 can be fit into 170 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 153 from 170 to get 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 51

Step 4:
When dividing 172 by 51, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 133.0
Subtract 153 from 172 to get 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 51

Moving on to step 5:
If we divide 194 by 51, we get 3 and a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 1333.0
Subtracting 153 from 194 leaves us with 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 51

Let's proceed to step 6:
413 divided by 51 is 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 13338.0
If we subtract 408 from 413, 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.

Advancing to step 7:
51 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 13338.0
Subtract 0 from 50 to 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.

Going ahead to step 8:
When dividing 500 by 51, we get 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 13338.09
Subtracting 459 from 500 leaves us 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.

Advancing to step 9:
51 goes into 410 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 13338.098
Deduct 408 from 410 and we're left 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.

Moving on to step 10:
20 divided by 51 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 13338.098
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
51 goes into 200 3 times with a remainder of 47.
The next digit of our result is 3. 
Result so far: 13338.09803
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
When dividing 470 by 51, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 13338.098039
Subtract 459 from 470 to 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.

Moving on to step 13:
110 divided by 51 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 13338.0980392
If we take 102 away from 110, we end up 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 14:
80 divided by 51 is 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 13338.09803921
If we take 51 away from 80, we end up 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.

The final outcome is 13338.09803921, with a leftover of 2.9e-08.
