Let's divide 8437 by 4
We want to divide 8437 by 4.

On to step 1:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 8 from 8, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 4

Going ahead to step 2:
4 goes into 4 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 4 from 4, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 4

Moving on to step 3:
4 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 210.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 4

Moving on to step 4:
37 divided by 4 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 2109.0
If we take 36 away from 37, 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.

On to step 5:
If we divide 10 by 4, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2109.2
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.

Let's proceed to step 6:
20 divided by 4 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2109.25
Deduct 20 from 20 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.

On to step 7:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2109.25
If we take 0 away from 0, we end up 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.

Moving on to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2109.25
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.

Our division results in 2109.25 with a remaining 0.0.
