219970 divided by 23 
The aim is to understand the frequency of 23 in 219970.

Going ahead to step 1:
23 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 23

Step 2:
23 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 23

On to step 3:
When dividing 219 by 23, we get 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 207 away from 219, we end up with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 23

Advancing to step 4:
If we divide 129 by 23, we get 5 and a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we take 115 away from 129, we end up with 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 23

Step 5:
23 can be fit into 147 6 times, resulting in a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 956.0
Deduct 138 from 147 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 23

Moving on to step 6:
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: 9563.0
Subtracting 69 from 90 leaves us 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.

On to step 7:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 9563.9
Subtracting 207 from 210 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 8:
If we divide 30 by 23, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 9563.91
If we subtract 23 from 30, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 9563.913
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.

Let's proceed to step 10:
23 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 9563.913
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
If we divide 100 by 23, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 9563.91304
If we subtract 92 from 100, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 9563.913043
Deduct 69 from 80 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
When dividing 110 by 23, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 9563.9130434
Subtract 92 from 110 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 9563.91304347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 9563.91304347, with a leftover of 1.9e-08.
