212930 divided by 28 
The aim is to understand the frequency of 28 in 212930.

Going ahead to step 1:
28 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 28

Going ahead to step 2:
21 divided by 28 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 28

Let's proceed to step 3:
If we divide 212 by 28, we get 7 and a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 196 from 212 to get 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 28

Going ahead to step 4:
The number 28 fits into 169 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
The remainder is 1 after subtracting 168 from 169.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 28

Advancing to step 5:
The number 28 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 760.0
Subtract 0 from 13 to get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 28

Moving on to step 6:
The number 28 fits into 130 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 7604.0
Subtract 112 from 130 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 28 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 7604.6
Deduct 168 from 180 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.

Let's proceed to step 8:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 7604.64
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.

Step 9:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 7604.642
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.

Step 10:
28 goes into 240 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7604.6428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 7604.64285
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
If we divide 200 by 28, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 7604.642857
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.

Let's proceed to step 13:
If we divide 40 by 28, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 7604.6428571
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.

Step 14:
If we divide 120 by 28, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 7604.64285714
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.

The final outcome is 7604.64285714, with a leftover of 8e-09.
