108210 ÷ 28 
Let's see how many times 28 fits into 108210.

Advancing to step 1:
When dividing 1 by 28, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 28

Moving on to step 2:
When dividing 10 by 28, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 28

Going ahead to step 3:
The number 28 fits into 108 3 times, leaving a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 84 from 108 and we're left with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 28

Step 4:
When dividing 242 by 28, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we take 224 away from 242, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 28

Going ahead to step 5:
When dividing 181 by 28, we get 6 with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 386.0
If we take 168 away from 181, we end up with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 28

Moving on to step 6:
If we divide 130 by 28, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 3864.0
The remainder is 18 after subtracting 112 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
When dividing 180 by 28, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 3864.6
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 28, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3864.64
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 28 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 3864.642
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 3864.6428
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 28, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 3864.64285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
When dividing 200 by 28, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 3864.642857
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 3864.6428571
If we take 28 away from 40, we end up 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.

On to step 14:
If we divide 120 by 28, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3864.64285714
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 3864.64285714 with a remainder of 8e-09.
