874286 divided by 51 
We want to figure out the number of times 874286 can be divided by 51.

Advancing to step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 51

Step 2:
The number 51 fits into 87 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 51 from 87 leaves us with 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 51

Advancing to step 3:
51 can be fit into 364 7 times, resulting in 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.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 51

Moving on to step 4:
72 divided by 51 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 171.0
The remainder is 21 after subtracting 51 from 72.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 51

Moving on to step 5:
If we divide 218 by 51, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 1714.0
If we subtract 204 from 218, we get 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 51

On to step 6:
When dividing 146 by 51, we get 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 17142.0
Deduct 102 from 146 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
When dividing 440 by 51, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 17142.8
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
320 divided by 51 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 17142.86
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
When dividing 140 by 51, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 17142.862
If we take 102 away from 140, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
380 divided by 51 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 17142.8627
Subtracting 357 from 380 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
When dividing 230 by 51, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 17142.86274
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
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: 17142.862745
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
If we divide 50 by 51, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 17142.862745
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.

Let's proceed to step 14:
If we divide 500 by 51, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 17142.86274509
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.

Our division results in 17142.86274509 with a remaining 4.1e-08.
