Let's divide 405778 by 51
Our goal is to divide 405778 by 51.

Let's proceed to step 1:
When dividing 4 by 51, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 51

Step 2:
If we divide 40 by 51, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 51

Moving on to step 3:
51 can be fit into 405 7 times, resulting in a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 357 from 405 leaves us with 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 51

Going ahead to step 4:
When dividing 487 by 51, we get 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 79.0
The remainder is 28 after subtracting 459 from 487.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 51

Advancing to step 5:
287 divided by 51 is 5 with a remainder of 32.
The next digit of our result is 5. 
Result so far: 795.0
If we take 255 away from 287, we end up with 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 51

Step 6:
328 divided by 51 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 7956.0
Deduct 306 from 328 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
51 goes into 220 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 7956.4
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
51 goes into 160 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 7956.43
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
70 divided by 51 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 7956.431
Subtracting 51 from 70 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 7956.4313
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
When dividing 370 by 51, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 7956.43137
Subtracting 357 from 370 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
When dividing 130 by 51, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 7956.431372
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
280 divided by 51 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 7956.4313725
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 14:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 7956.43137254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 7956.43137254, with a leftover of 4.6e-08.
