We look at the division of 400811 by 51 
We want to figure out the number of times 400811 can be divided by 51.

Moving on to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 51

Let's proceed to step 2:
40 divided by 51 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 51

Moving on to step 3:
If we divide 400 by 51, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 43 after subtracting 357 from 400.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 51

Going ahead to step 4:
When dividing 438 by 51, we get 8 with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 408 from 438 and we're left with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 51

Let's proceed to step 5:
51 goes into 301 5 times with a remainder of 46.
The next digit of our result is 5. 
Result so far: 785.0
Subtract 255 from 301 to get 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 51

Going ahead to step 6:
When dividing 461 by 51, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 7859.0
Subtracting 459 from 461 leaves us 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.

Let's proceed to step 7:
51 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7859.0
Subtracting 0 from 20 leaves us 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 8:
200 divided by 51 is 3 with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 7859.03
Deduct 153 from 200 and we're left 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.

On to step 9:
470 divided by 51 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 7859.039
If we take 459 away from 470, we end up 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.

On to step 10:
When dividing 110 by 51, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 7859.0392
If we subtract 102 from 110, we get 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 11:
When dividing 80 by 51, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 7859.03921
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.

On to step 12:
51 can be fit into 290 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 7859.039215
Subtract 255 from 290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
The number 51 fits into 350 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 7859.0392156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
440 divided by 51 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 7859.03921568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 7859.03921568, and the remainder is 3.2e-08.
