Let's divide 51866711 by 859
We want to figure out the number of times 51866711 can be divided by 859.

Let's proceed to step 1:
When dividing 5 by 859, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 859

Moving on to step 2:
859 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 859

Step 3:
859 goes into 518 0 times with a remainder of 518.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 518 leaves us with 518.
Take the next digit (6) from the dividend and append it to 518, then repeat: 5186 / 859

Let's proceed to step 4:
859 can be fit into 5186 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 5154 from 5186, we get 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 859

On to step 5:
859 can be fit into 326 0 times, resulting in a remainder of 326.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Deduct 0 from 326 and we're left with 326.
Include the next digit (7) from the dividend after 326, then repeat: 3267 / 859

Moving on to step 6:
3267 divided by 859 is 3 with a remainder of 690.
Use 3 as the next digit of our solution. 
Result so far: 603.0
The remainder is 690 after subtracting 2577 from 3267.
Include the next digit (1) from the dividend after 690, then repeat: 6901 / 859

Advancing to step 7:
859 goes into 6901 8 times with a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 6038.0
The remainder is 29 after subtracting 6872 from 6901.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 859

Moving on to step 8:
The number 859 fits into 291 0 times, leaving a remainder of 291.
The number 0 becomes the next digit in our result. 
Result so far: 60380.0
If we subtract 0 from 291, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 9:
859 goes into 2910 3 times with a remainder of 333.
The number 3 becomes the next digit in our result. 
Result so far: 60380.3
Subtracting 2577 from 2910 leaves us with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Step 10:
859 goes into 3330 3 times with a remainder of 753.
The next digit of our result is 3. 
Result so far: 60380.33
Deduct 2577 from 3330 and we're left with 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

Our division results in 60380.33 with a remaining 0.753.
