821145 ÷ 4 
We're looking to find how many times 4 goes into 821145.

Let's proceed to step 1:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 8 from 8, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 4

Advancing to step 2:
If we divide 2 by 4, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 4

Moving on to step 3:
4 can be fit into 21 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 205.0
If we subtract 20 from 21, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

Step 4:
4 goes into 11 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2052.0
Deduct 8 from 11 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 4

Going ahead to step 5:
If we divide 34 by 4, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 20528.0
If we subtract 32 from 34, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 4

Moving on to step 6:
25 divided by 4 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 205286.0
If we take 24 away from 25, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 205286.2
If we take 8 away from 10, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 205286.25
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 205286.25
Subtract 0 from 0 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:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 205286.25
The remainder is 0 after subtracting 0 from 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 quotient of the division is 205286.25, and the remainder is 0.0.
