We look at the division of 21658853 by 856 
We're looking to find how many times 856 goes into 21658853.

Going ahead to step 1:
If we divide 2 by 856, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 856

Advancing to step 2:
856 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 856

Step 3:
216 divided by 856 is 0 with a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Include the next digit (5) from the dividend after 216, then repeat: 2165 / 856

Moving on to step 4:
If we divide 2165 by 856, we get 2 and a remainder of 453.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1712 from 2165 and we're left with 453.
Fetch the next digit (8) from the dividend, attach it to 453 and continue: 4538 / 856

On to step 5:
The number 856 fits into 4538 5 times, leaving a remainder of 258.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 4280 from 4538, we get 258.
Include the next digit (8) from the dividend after 258, then repeat: 2588 / 856

Step 6:
If we divide 2588 by 856, we get 3 and a remainder of 20.
The next digit of our result is 3. 
Result so far: 253.0
If we subtract 2568 from 2588, we get 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 856

On to step 7:
856 goes into 205 0 times with a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 2530.0
Subtract 0 from 205 to get 205.
Include the next digit (3) from the dividend after 205, then repeat: 2053 / 856

Advancing to step 8:
856 can be fit into 2053 2 times, resulting in a remainder of 341.
Put 2 as the next digit of the answer. 
Result so far: 25302.0
The remainder is 341 after subtracting 1712 from 2053.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 9:
When dividing 3410 by 856, we get 3 with a remainder of 842.
The number 3 becomes the next digit in our result. 
Result so far: 25302.3
Deduct 2568 from 3410 and we're left with 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Step 10:
856 goes into 8420 9 times with a remainder of 716.
The number 9 becomes the next digit in our result. 
Result so far: 25302.39
If we take 7704 away from 8420, we end up with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Advancing to step 11:
When dividing 7160 by 856, we get 8 with a remainder of 312.
Put 8 as the next digit of the answer. 
Result so far: 25302.398
Deduct 6848 from 7160 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 12:
The number 856 fits into 3120 3 times, leaving a remainder of 552.
The next digit of our result is 3. 
Result so far: 25302.3983
Subtract 2568 from 3120 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 13:
856 goes into 5520 6 times with a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 25302.39836
The remainder is 384 after subtracting 5136 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 14:
When dividing 3840 by 856, we get 4 with a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 25302.398364
If we subtract 3424 from 3840, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 15:
If we divide 4160 by 856, we get 4 and a remainder of 736.
Write down 4 as next digit of the result. 
Result so far: 25302.3983644
Deduct 3424 from 4160 and we're left with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The quotient of the division is 25302.3983644, and the remainder is 7.36e-06.
