We're dividing 173570 by 23 
The aim is to understand the frequency of 23 in 173570.

Advancing to step 1:
When dividing 1 by 23, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 23

Let's proceed to step 2:
The number 23 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 23

Advancing to step 3:
23 goes into 173 7 times with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 12 after subtracting 161 from 173.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 23

Let's proceed to step 4:
If we divide 125 by 23, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Subtracting 115 from 125 leaves us with 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 23

Advancing to step 5:
If we divide 107 by 23, we get 4 and a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 754.0
Subtract 92 from 107 to get 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 23

Moving on to step 6:
23 goes into 150 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 7546.0
If we subtract 138 from 150, we 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.

Advancing to step 7:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7546.5
If we subtract 115 from 120, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 7546.52
If we take 46 away from 50, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 7546.521
Deduct 23 from 40 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
23 can be fit into 170 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7546.5217
The remainder is 9 after subtracting 161 from 170.
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 11:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 7546.52173
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 12:
When dividing 210 by 23, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 7546.521739
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.

On to step 13:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 7546.5217391
Subtracting 23 from 30 leaves us 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.

Going ahead to step 14:
70 divided by 23 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 7546.52173913
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 7546.52173913 with a balance of 1e-09.
