871450 divided by 51 
We want to figure out the number of times 871450 can be divided by 51.

Let's proceed to step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 51

On to step 2:
51 can be fit into 87 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 51 from 87 to get 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 51

Advancing to step 3:
51 goes into 361 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 4 after subtracting 357 from 361.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 51

Step 4:
51 goes into 44 0 times with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
Subtract 0 from 44 to get 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 51

Going ahead to step 5:
445 divided by 51 is 8 with a remainder of 37.
The next digit of our result is 8. 
Result so far: 1708.0
If we take 408 away from 445, we end up with 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 51

On to step 6:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 17087.0
Deduct 357 from 370 and we're left 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.

On to step 7:
51 goes into 130 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 17087.2
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
If we divide 280 by 51, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 17087.25
If we subtract 255 from 280, we get 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 9:
51 goes into 250 4 times with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 17087.254
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.

Moving on to step 10:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 17087.2549
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
When dividing 10 by 51, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 17087.2549
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
51 goes into 100 1 times with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 17087.254901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 13:
51 can be fit into 490 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 17087.2549019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 14:
When dividing 310 by 51, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 17087.25490196
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 17087.25490196 with a balance of 4e-09.
