92853 ÷ 21 
We want to figure out the number of times 92853 can be divided by 21.

Step 1:
21 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 21

Let's proceed to step 2:
When dividing 92 by 21, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 84 from 92 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 21

Going ahead to step 3:
21 can be fit into 88 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 84 from 88 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 21

On to step 4:
21 goes into 45 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 442.0
If we take 42 away from 45, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 21

Going ahead to step 5:
21 goes into 33 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 4421.0
Subtracting 21 from 33 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 6:
21 goes into 120 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 4421.5
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
When dividing 150 by 21, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 4421.57
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 4421.571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4421.5714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
60 divided by 21 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 4421.57142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
180 divided by 21 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 4421.571428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
When dividing 120 by 21, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4421.5714285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
When dividing 150 by 21, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 4421.57142857
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 4421.57142857 with a remainder of 3e-09.
