357599 ÷ 23 
The aim is to understand the frequency of 23 in 357599.

On to step 1:
3 divided by 23 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 23

Step 2:
When dividing 35 by 23, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 23 from 35 to get 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 23

Let's proceed to step 3:
127 divided by 23 is 5 with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 12 after subtracting 115 from 127.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 23

Step 4:
When dividing 125 by 23, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 155.0
The remainder is 10 after subtracting 115 from 125.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 23

On to step 5:
109 divided by 23 is 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 1554.0
If we take 92 away from 109, we end up with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 23

Let's proceed to step 6:
179 divided by 23 is 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 15547.0
Deduct 161 from 179 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
When dividing 180 by 23, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 15547.7
Deduct 161 from 180 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
When dividing 190 by 23, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 15547.78
The remainder is 6 after subtracting 184 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
60 divided by 23 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 15547.782
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
23 goes into 140 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 15547.7826
Subtract 138 from 140 to get 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 11:
20 divided by 23 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 15547.7826
Deduct 0 from 20 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.

Let's proceed to step 12:
200 divided by 23 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 15547.782608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 23, we get 6 and a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 15547.7826086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 15547.78260869
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 15547.78260869, and the remainder is 1.3e-08.
