We divide 681581 by 51
Our goal is to divide 681581 by 51.

Moving on to step 1:
51 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 51

Moving on to step 2:
If we divide 68 by 51, we get 1 and 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 (1) from the dividend and append it to 17, then repeat: 171 / 51

Step 3:
If we divide 171 by 51, we get 3 and a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 153 from 171 leaves us with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 51

Moving on to step 4:
51 can be fit into 185 3 times, resulting in a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 133.0
Subtracting 153 from 185 leaves us with 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 51

On to step 5:
When dividing 328 by 51, we get 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 1336.0
If we subtract 306 from 328, we get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 51

Moving on to step 6:
If we divide 221 by 51, we get 4 and a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 13364.0
If we take 204 away from 221, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
When dividing 170 by 51, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 13364.3
If we take 153 away from 170, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
170 divided by 51 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 13364.33
Subtract 153 from 170 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 13364.33 with a remaining 0.017.
