874935 ÷ 51 
Let's see how many times 51 fits into 874935.

Step 1:
51 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 51

On to step 2:
When dividing 87 by 51, we get 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 51 from 87 leaves us with 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 51

Let's proceed to step 3:
51 goes into 364 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 17.0
If we take 357 away from 364, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 51

Going ahead to step 4:
When dividing 79 by 51, we get 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 171.0
The remainder is 28 after subtracting 51 from 79.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 51

Step 5:
51 goes into 283 5 times with a remainder of 28.
The next digit of our result is 5. 
Result so far: 1715.0
The remainder is 28 after subtracting 255 from 283.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 51

Let's proceed to step 6:
If we divide 285 by 51, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 17155.0
If we take 255 away from 285, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
51 goes into 300 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 17155.5
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
When dividing 450 by 51, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 17155.58
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
The number 51 fits into 420 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 17155.588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 17155.588 with a remainder of 0.0012.
