We divide 860878 by 51
We want to figure out the number of times 860878 can be divided by 51.

Moving on to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 51

Going ahead to step 2:
51 can be fit into 86 1 times, resulting in a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 35 after subtracting 51 from 86.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 51

Advancing to step 3:
51 can be fit into 350 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 306 from 350 and we're left with 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 51

Step 4:
If we divide 448 by 51, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 168.0
Deduct 408 from 448 and we're left with 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 51

Going ahead to step 5:
407 divided by 51 is 7 with a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 1687.0
The remainder is 50 after subtracting 357 from 407.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 51

Let's proceed to step 6:
If we divide 508 by 51, we get 9 and a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 16879.0
Subtracting 459 from 508 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
If we divide 490 by 51, we get 9 and a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 16879.9
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 8:
The number 51 fits into 310 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 16879.96
If we take 306 away from 310, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 51 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 16879.96
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
The number 51 fits into 400 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 16879.9607
Deduct 357 from 400 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
The number 51 fits into 430 8 times, leaving a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 16879.96078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
If we divide 220 by 51, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 16879.960784
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
51 can be fit into 160 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 16879.9607843
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
When dividing 70 by 51, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 16879.96078431
If we subtract 51 from 70, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 16879.96078431, with a leftover of 1.9e-08.
