We're dividing 18663704 by 856 
We want to divide 18663704 by 856.

On to step 1:
856 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 856

Going ahead to step 2:
18 divided by 856 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 856

Moving on to step 3:
856 goes into 186 0 times with a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 186, we end up with 186.
Fetch the next digit (6) from the dividend, attach it to 186 and continue: 1866 / 856

Let's proceed to step 4:
The number 856 fits into 1866 2 times, leaving a remainder of 154.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1712 from 1866 to get 154.
Append the next digit (3) from the dividend to 154 and continue with: 1543 / 856

Step 5:
856 goes into 1543 1 times with a remainder of 687.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 856 from 1543 leaves us with 687.
Take the next digit (7) from the dividend and append it to 687, then repeat: 6877 / 856

Going ahead to step 6:
6877 divided by 856 is 8 with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
If we subtract 6848 from 6877, we get 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 856

Advancing to step 7:
290 divided by 856 is 0 with a remainder of 290.
Use 0 as the next digit of our solution. 
Result so far: 2180.0
Deduct 0 from 290 and we're left with 290.
Fetch the next digit (4) from the dividend, attach it to 290 and continue: 2904 / 856

On to step 8:
856 goes into 2904 3 times with a remainder of 336.
Record the quotient 3 as the next digit in the result. 
Result so far: 21803.0
Subtract 2568 from 2904 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 9:
When dividing 3360 by 856, we get 3 with a remainder of 792.
Record the quotient 3 as the next digit in the result. 
Result so far: 21803.3
The remainder is 792 after subtracting 2568 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 10:
If we divide 7920 by 856, we get 9 and a remainder of 216.
Put 9 as the next digit of the answer. 
Result so far: 21803.39
The remainder is 216 after subtracting 7704 from 7920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 11:
If we divide 2160 by 856, we get 2 and a remainder of 448.
The number 2 becomes the next digit in our result. 
Result so far: 21803.392
Subtract 1712 from 2160 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 12:
856 can be fit into 4480 5 times, resulting in a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 21803.3925
If we take 4280 away from 4480, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
The number 856 fits into 2000 2 times, leaving a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 21803.39252
If we subtract 1712 from 2000, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 14:
856 goes into 2880 3 times with a remainder of 312.
The number 3 becomes the next digit in our result. 
Result so far: 21803.392523
The remainder is 312 after subtracting 2568 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 15:
3120 divided by 856 is 3 with a remainder of 552.
The next digit of our result is 3. 
Result so far: 21803.3925233
If we take 2568 away from 3120, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

The final outcome is 21803.3925233, with a leftover of 5.52e-06.
