We're dividing 890910 by 23 
The aim is to understand the frequency of 23 in 890910.

Going ahead to step 1:
23 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 23

On to step 2:
When dividing 89 by 23, we get 3 with a remainder of 20.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 69 from 89 to get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 23

On to step 3:
If we divide 200 by 23, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 184 from 200 and we're left with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 23

Going ahead to step 4:
23 goes into 169 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 387.0
If we take 161 away from 169, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 23

Going ahead to step 5:
The number 23 fits into 81 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 3873.0
If we take 69 away from 81, we end up with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 23

Going ahead to step 6:
23 goes into 120 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 38735.0
Subtracting 115 from 120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 23, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 38735.2
Subtract 46 from 50 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.

Step 8:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 38735.21
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 38735.217
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
When dividing 90 by 23, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 38735.2173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 38735.21739
Deduct 207 from 210 and we're left 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.

Advancing to step 12:
30 divided by 23 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 38735.217391
If we take 23 away from 30, we end up with 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 13:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 38735.2173913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
23 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 38735.2173913
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 38735.2173913, and the remainder is 1e-08.
