139291 divided by 23 
The aim is to understand the frequency of 23 in 139291.

Advancing to step 1:
When dividing 1 by 23, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 23

Advancing to step 2:
If we divide 13 by 23, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 23

Step 3:
23 can be fit into 139 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 138 from 139 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 23

Let's proceed to step 4:
23 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 23

Let's proceed to step 5:
23 goes into 129 5 times with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 605.0
Deduct 115 from 129 and we're left with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 23

Let's proceed to step 6:
The number 23 fits into 141 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 6056.0
Subtract 138 from 141 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
23 goes into 30 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 6056.1
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
When dividing 70 by 23, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 6056.13
If we take 69 away from 70, we end up 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.

Step 9:
10 divided by 23 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 6056.13
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.

Going ahead to step 10:
The number 23 fits into 100 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 6056.1304
Deduct 92 from 100 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
80 divided by 23 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 6056.13043
If we take 69 away from 80, we end up 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.

Advancing to step 12:
When dividing 110 by 23, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 6056.130434
If we take 92 away from 110, we end up 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.

On to step 13:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 6056.1304347
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
190 divided by 23 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 6056.13043478
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.

The quotient of the division is 6056.13043478, and the remainder is 6e-09.
