146986 divided by 23 
The aim is to understand the frequency of 23 in 146986.

Step 1:
23 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 23

Going ahead to step 2:
23 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 23

Moving on to step 3:
When dividing 146 by 23, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 138 from 146 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 23

Going ahead to step 4:
89 divided by 23 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtract 69 from 89 to get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 23

Step 5:
208 divided by 23 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 639.0
Deduct 207 from 208 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 23

Let's proceed to step 6:
When dividing 16 by 23, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 6390.0
If we subtract 0 from 16, we 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.

Moving on to step 7:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 6390.6
If we take 138 away from 160, we end up 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.

Moving on to step 8:
When dividing 220 by 23, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 6390.69
If we subtract 207 from 220, we 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.

Moving on to step 9:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 6390.695
Deduct 115 from 130 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
23 goes into 150 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 6390.6956
Deduct 138 from 150 and we're left 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.

Advancing to step 11:
When dividing 120 by 23, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6390.69565
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.

On to step 12:
If we divide 50 by 23, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 6390.695652
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 13:
If we divide 40 by 23, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 6390.6956521
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.

Advancing to step 14:
170 divided by 23 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 6390.69565217
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.

The final outcome is 6390.69565217, with a leftover of 9e-09.
