873956 ÷ 28 
The aim is to understand the frequency of 28 in 873956.

Advancing to step 1:
28 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 28

Step 2:
When dividing 87 by 28, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 84 from 87 and we're left with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 28

Advancing to step 3:
The number 28 fits into 33 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 28 from 33 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 28

Going ahead to step 4:
The number 28 fits into 59 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 312.0
The remainder is 3 after subtracting 56 from 59.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 28

Step 5:
If we divide 35 by 28, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 3121.0
The remainder is 7 after subtracting 28 from 35.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 28

Advancing to step 6:
28 goes into 76 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 31212.0
Subtract 56 from 76 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.

On to step 7:
When dividing 200 by 28, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 31212.7
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.

Advancing to step 8:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 31212.71
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.

Advancing to step 9:
When dividing 120 by 28, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 31212.714
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.

On to step 10:
If we divide 80 by 28, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 31212.7142
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.

Advancing to step 11:
If we divide 240 by 28, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 31212.71428
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.

On to step 12:
160 divided by 28 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 31212.714285
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.

On to step 13:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 31212.7142857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 31212.71428571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 31212.71428571 with a balance of 1.2e-08.
