738839 ÷ 28 
The aim is to understand the frequency of 28 in 738839.

Going ahead to step 1:
If we divide 7 by 28, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 28

Going ahead to step 2:
If we divide 73 by 28, we get 2 and a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 56 away from 73, we end up with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 28

Moving on to step 3:
If we divide 178 by 28, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 10 after subtracting 168 from 178.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 28

On to step 4:
When dividing 108 by 28, we get 3 with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 263.0
Subtracting 84 from 108 leaves us with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 28

On to step 5:
The number 28 fits into 243 8 times, leaving a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 2638.0
Subtracting 224 from 243 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 28

Going ahead to step 6:
If we divide 199 by 28, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 26387.0
Subtracting 196 from 199 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 28 fits into 30 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 26387.1
Subtracting 28 from 30 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 28 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 26387.1
Subtract 0 from 20 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.

Let's proceed to step 9:
28 goes into 200 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 26387.107
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.

Moving on to step 10:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 26387.1071
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.

Going ahead to step 11:
28 goes into 120 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 26387.10714
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.

On to step 12:
80 divided by 28 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 26387.107142
Subtract 56 from 80 to get 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 13:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 26387.1071428
If we subtract 224 from 240, we 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.

Step 14:
If we divide 160 by 28, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 26387.10714285
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.

The final result is 26387.10714285 with a remainder of 2e-08.
