Let's divide 680855 by 51
We want to divide 680855 by 51.

Step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
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.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 51 from 68 and we're left with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 51

Step 3:
When dividing 170 by 51, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 153 from 170 and we're left with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 51

Advancing to step 4:
When dividing 178 by 51, we get 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 133.0
Deduct 153 from 178 and we're left with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 51

Step 5:
255 divided by 51 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1335.0
If we subtract 255 from 255, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 51

Moving on to step 6:
The number 51 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 13350.0
If we subtract 0 from 5, 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.

Moving on to step 7:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 13350.0
If we subtract 0 from 50, we 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.

Step 8:
If we divide 500 by 51, we get 9 and a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 13350.09
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
When dividing 410 by 51, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 13350.098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
If we divide 20 by 51, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 13350.098
Subtract 0 from 20 to get 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:
The number 51 fits into 200 3 times, leaving a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 13350.09803
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.

Moving on to step 12:
When dividing 470 by 51, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 13350.098039
Deduct 459 from 470 and we're left 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.

Let's proceed to step 13:
When dividing 110 by 51, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 13350.0980392
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.

Step 14:
51 goes into 80 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 13350.09803921
Subtract 51 from 80 to 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.

The final result is 13350.09803921 with a remainder of 2.9e-08.
