861821 divided by 56 
We want to divide 861821 by 56.

Moving on to step 1:
When dividing 8 by 56, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 56

Let's proceed to step 2:
56 can be fit into 86 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 30 after subtracting 56 from 86.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 56

Step 3:
56 can be fit into 301 5 times, resulting in a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 280 from 301 to get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 56

Let's proceed to step 4:
The number 56 fits into 218 3 times, leaving a remainder of 50.
The next digit of our result is 3. 
Result so far: 153.0
Deduct 168 from 218 and we're left with 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 56

Moving on to step 5:
56 can be fit into 502 8 times, resulting in a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 1538.0
Subtracting 448 from 502 leaves us with 54.
Take the next digit (1) from the dividend and append it to 54, then repeat: 541 / 56

Step 6:
56 can be fit into 541 9 times, resulting in a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 15389.0
The remainder is 37 after subtracting 504 from 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
56 can be fit into 370 6 times, resulting in a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 15389.6
Deduct 336 from 370 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
When dividing 340 by 56, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 15389.66
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 15389.66, with a leftover of 0.004.
