858263 ÷ 56 
Our goal is to divide 858263 by 56.

Let's proceed to step 1:
56 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 56

On to step 2:
The number 56 fits into 85 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 56 from 85 and we're left with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 56

Moving on to step 3:
If we divide 298 by 56, we get 5 and a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 280 from 298 to get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 56

Moving on to step 4:
56 can be fit into 182 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 153.0
The remainder is 14 after subtracting 168 from 182.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 56

Advancing to step 5:
56 goes into 146 2 times with a remainder of 34.
The next digit of our result is 2. 
Result so far: 1532.0
If we take 112 away from 146, we end up with 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 56

Moving on to step 6:
If we divide 343 by 56, we get 6 and a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 15326.0
The remainder is 7 after subtracting 336 from 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
When dividing 70 by 56, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 15326.1
If we take 56 away from 70, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
If we divide 140 by 56, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 15326.12
Subtract 112 from 140 to 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 9:
When dividing 280 by 56, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15326.125
Subtract 280 from 280 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 56, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15326.125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
56 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15326.125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 15326.125 with a remainder of 0.0.
