We look at the division of 866187 by 56 
Our goal is to divide 866187 by 56.

Advancing to step 1:
The number 56 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 56

Let's proceed to step 2:
56 can be fit into 86 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 56 from 86 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 56

Step 3:
56 goes into 306 5 times with a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 280 from 306 to get 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 56

On to step 4:
If we divide 261 by 56, we get 4 and a remainder of 37.
The next digit of our result is 4. 
Result so far: 154.0
Subtract 224 from 261 to get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 56

Step 5:
378 divided by 56 is 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 1546.0
Subtract 336 from 378 to get 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 56

Moving on to step 6:
When dividing 427 by 56, we get 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 15467.0
Deduct 392 from 427 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
If we divide 350 by 56, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 15467.6
The remainder is 14 after subtracting 336 from 350.
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:
The number 56 fits into 140 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 15467.62
If we take 112 away from 140, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
280 divided by 56 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15467.625
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.

On to step 10:
If we divide 0 by 56, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15467.625
Deduct 0 from 0 and we're left 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.

Going ahead to step 11:
The number 56 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15467.625
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 outcome is 15467.625, with a leftover of 0.0.
