261409 divided by 51 
Our goal is to divide 261409 by 51.

Moving on to step 1:
2 divided by 51 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 51

On to step 2:
If we divide 26 by 51, we get 0 and a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 51

Advancing to step 3:
261 divided by 51 is 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 255 from 261 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 51

On to step 4:
64 divided by 51 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 51 from 64 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 51

On to step 5:
51 can be fit into 130 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 512.0
The remainder is 28 after subtracting 102 from 130.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 51

Advancing to step 6:
When dividing 289 by 51, we get 5 with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 5125.0
Deduct 255 from 289 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
340 divided by 51 is 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 5125.6
Subtract 306 from 340 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
When dividing 340 by 51, we get 6 with a remainder of 34.
The number 6 becomes the next digit in our result.
