125832 divided by 13 
The aim is to understand the frequency of 13 in 125832.

Let's proceed to step 1:
The number 13 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 13

Step 2:
12 divided by 13 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 13

On to step 3:
When dividing 125 by 13, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 117 from 125 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 13

Step 4:
The number 13 fits into 88 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 96.0
Subtracting 78 from 88 leaves us with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 13

Moving on to step 5:
103 divided by 13 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 967.0
Subtract 91 from 103 to get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 13

Let's proceed to step 6:
122 divided by 13 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 9679.0
The remainder is 5 after subtracting 117 from 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
When dividing 50 by 13, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 9679.3
Subtracting 39 from 50 leaves us 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 8:
13 can be fit into 110 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 9679.38
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 13, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 9679.384
If we subtract 52 from 60, 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.

Going ahead to step 10:
If we divide 80 by 13, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 9679.3846
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
13 goes into 20 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 9679.38461
Deduct 13 from 20 and we're left 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.

Advancing to step 12:
When dividing 70 by 13, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 9679.384615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
If we divide 50 by 13, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 9679.3846153
Deduct 39 from 50 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.

Advancing to step 14:
110 divided by 13 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 9679.38461538
Deduct 104 from 110 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 9679.38461538 with a remaining 6e-09.
