872845 ÷ 4 
Our goal is to divide 872845 by 4.

Step 1:
If we divide 8 by 4, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 4

Step 2:
7 divided by 4 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 4 from 7 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 4

Step 3:
4 can be fit into 32 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 218.0
The remainder is 0 after subtracting 32 from 32.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Moving on to step 4:
8 divided by 4 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2182.0
Deduct 8 from 8 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 4

On to step 5:
If we divide 4 by 4, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21821.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 4

Let's proceed to step 6:
If we divide 5 by 4, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 218211.0
If we subtract 4 from 5, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
4 goes into 10 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 218211.2
Subtract 8 from 10 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 218211.25
Subtract 20 from 20 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.

Step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 218211.25
If we subtract 0 from 0, we 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:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 218211.25
Deduct 0 from 0 and we're left with 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 final result is 218211.25 with a remainder of 0.0.
