We're dividing 139216 by 23 
The aim is to understand the frequency of 23 in 139216.

Going ahead to step 1:
The number 23 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 23

On to step 2:
23 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 23

Step 3:
When dividing 139 by 23, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 138 away from 139, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 23

Advancing to step 4:
If we divide 12 by 23, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 23

Step 5:
23 can be fit into 121 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 605.0
Subtracting 115 from 121 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 23

On to step 6:
66 divided by 23 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 6052.0
If we subtract 46 from 66, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
When dividing 200 by 23, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 6052.8
Subtract 184 from 200 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.

On to step 8:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 6052.86
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
When dividing 220 by 23, we get 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 6052.869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
23 goes into 130 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 6052.8695
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
23 goes into 150 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 6052.86956
If we take 138 away from 150, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
23 goes into 120 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6052.869565
Deduct 115 from 120 and we're left 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.

Step 13:
50 divided by 23 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 6052.8695652
Deduct 46 from 50 and we're left 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.

Let's proceed to step 14:
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: 6052.86956521
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.

After the division, we end up with 6052.86956521 and a remainder of 1.7e-08.
