We divide 890599 by 28
The aim is to understand the frequency of 28 in 890599.

Going ahead to step 1:
The number 28 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 28

Let's proceed to step 2:
When dividing 89 by 28, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 5 after subtracting 84 from 89.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 28

Moving on to step 3:
When dividing 50 by 28, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 28 from 50 leaves us with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 28

On to step 4:
If we divide 225 by 28, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 318.0
Deduct 224 from 225 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 28

Let's proceed to step 5:
The number 28 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 3180.0
If we take 0 away from 19, we end up with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 28

Let's proceed to step 6:
28 can be fit into 199 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 31807.0
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.

Step 7:
28 goes into 30 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 31807.1
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.

On to step 8:
When dividing 20 by 28, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 31807.1
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 31807.107
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.

Moving on to step 10:
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: 31807.1071
Subtract 28 from 40 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.

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: 31807.10714
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.

Advancing to step 12:
80 divided by 28 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 31807.107142
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.

Let's proceed to step 13:
When dividing 240 by 28, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 31807.1071428
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 14:
If we divide 160 by 28, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 31807.10714285
Subtracting 140 from 160 leaves us 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.

The final outcome is 31807.10714285, with a leftover of 2e-08.
