We look at the division of 210345 by 4 
Let's see how many times 4 fits into 210345.

On to step 1:
4 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 4

Advancing to step 2:
4 goes into 21 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 20 from 21 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 4

Going ahead to step 3:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 8 away from 10, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 4

Step 4:
4 can be fit into 23 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 525.0
The remainder is 3 after subtracting 20 from 23.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 4

Moving on to step 5:
When dividing 34 by 4, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 5258.0
Subtract 32 from 34 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 4

On to step 6:
The number 4 fits into 25 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 52586.0
Deduct 24 from 25 and we're left 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 7:
4 goes into 10 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 52586.2
Deduct 8 from 10 and we're left 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.

Step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 52586.25
Subtracting 20 from 20 leaves us 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.

Going ahead to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 52586.25
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.

Moving on to step 10:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52586.25
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.

Our division results in 52586.25 with a remaining 0.0.
