We divide 402923 by 51
Let's see how many times 51 fits into 402923.

Step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 51

Let's proceed to step 2:
The number 51 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 51

Going ahead to step 3:
51 can be fit into 402 7 times, resulting in a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 357 from 402, we get 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 51

Step 4:
459 divided by 51 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
If we take 459 away from 459, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 51

Advancing to step 5:
The number 51 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 790.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 51

Let's proceed to step 6:
51 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 7900.0
If we subtract 0 from 23, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
51 goes into 230 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 7900.4
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
When dividing 260 by 51, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 7900.45
If we take 255 away from 260, we end up with 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 9:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7900.45
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
If we divide 500 by 51, we get 9 and a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 7900.4509
If we take 459 away from 500, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 11:
410 divided by 51 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 7900.45098
If we take 408 away from 410, we end up 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.

Advancing to step 12:
The number 51 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7900.45098
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 13:
When dividing 200 by 51, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 7900.4509803
The remainder is 47 after subtracting 153 from 200.
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 14:
When dividing 470 by 51, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 7900.45098039
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.

The final outcome is 7900.45098039, with a leftover of 1.1e-08.
