Let's divide 213212 by 28
We want to figure out the number of times 213212 can be divided by 28.

Going ahead to step 1:
If we divide 2 by 28, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 28

Moving on to step 2:
If we divide 21 by 28, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 28

Moving on to step 3:
The number 28 fits into 213 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 196 from 213 leaves us with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 28

On to step 4:
When dividing 172 by 28, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 168 from 172 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 28

Advancing to step 5:
28 can be fit into 41 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 761.0
If we take 28 away from 41, we end up with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 28

Step 6:
The number 28 fits into 132 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 7614.0
Deduct 112 from 132 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 7:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 7614.7
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 7614.71
Subtracting 28 from 40 leaves us 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.

Moving on to step 9:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 7614.714
If we take 112 away from 120, we end up 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.

Going ahead to step 10:
When dividing 80 by 28, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 7614.7142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 28, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7614.71428
Deduct 224 from 240 and we're left 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 12:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 7614.714285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
When dividing 200 by 28, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 7614.7142857
Deduct 196 from 200 and we're left 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.

Advancing to step 14:
40 divided by 28 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 7614.71428571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 7614.71428571 with a remaining 1.2e-08.
