We divide 219812 by 28
The aim is to understand the frequency of 28 in 219812.

On to step 1:
The number 28 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 28

Going ahead to step 2:
When dividing 21 by 28, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 28

Step 3:
If we divide 219 by 28, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 196 from 219 to get 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 28

Going ahead to step 4:
The number 28 fits into 238 8 times, leaving a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 224 from 238 leaves us with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 28

On to step 5:
If we divide 141 by 28, we get 5 and a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 785.0
If we take 140 away from 141, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 28

On to step 6:
The number 28 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 7850.0
Subtract 0 from 12 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.

Moving on to step 7:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 7850.4
If we subtract 112 from 120, we get 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 8:
When dividing 80 by 28, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 7850.42
If we take 56 away from 80, we end up 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.

Going ahead to step 9:
240 divided by 28 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 7850.428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 7850.4285
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.

Moving on to step 11:
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: 7850.42857
Subtracting 196 from 200 leaves us 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 12:
40 divided by 28 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 7850.428571
Deduct 28 from 40 and we're left 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.

Advancing to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 7850.4285714
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 14:
If we divide 80 by 28, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 7850.42857142
Subtracting 56 from 80 leaves us 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.

The quotient of the division is 7850.42857142, and the remainder is 2.4e-08.
