We divide 623931 by 28
The aim is to understand the frequency of 28 in 623931.

Going ahead to step 1:
28 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 28

Moving on to step 2:
28 goes into 62 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 56 from 62 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 28

Moving on to step 3:
63 divided by 28 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 56 away from 63, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 28

On to step 4:
79 divided by 28 is 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 222.0
Deduct 56 from 79 and we're left with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 28

Advancing to step 5:
28 goes into 233 8 times with a remainder of 9.
The next digit of our result is 8. 
Result so far: 2228.0
Subtracting 224 from 233 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 28

Going ahead to step 6:
28 can be fit into 91 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 22283.0
If we subtract 84 from 91, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 28 fits into 70 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 22283.2
If we subtract 56 from 70, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 28 fits into 140 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 22283.25
If we take 140 away from 140, we end up 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.

Advancing to step 9:
28 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22283.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 28, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22283.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 22283.25 with a balance of 0.0.
