920190 ÷ 13 
The aim is to understand the frequency of 13 in 920190.

Moving on to step 1:
13 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 13

Let's proceed to step 2:
When dividing 92 by 13, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 91 away from 92, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 13

On to step 3:
10 divided by 13 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 13

Advancing to step 4:
13 goes into 101 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 707.0
Subtract 91 from 101 to get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 13

Advancing to step 5:
When dividing 109 by 13, we get 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 7078.0
The remainder is 5 after subtracting 104 from 109.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 13

Step 6:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 70783.0
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.

Let's proceed to step 7:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 70783.8
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.

Step 8:
60 divided by 13 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 70783.84
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.

Let's proceed to step 9:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 70783.846
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 13, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 70783.8461
Subtracting 13 from 20 leaves us 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.

On to step 11:
70 divided by 13 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 70783.84615
Subtract 65 from 70 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
13 can be fit into 50 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 70783.846153
The remainder is 11 after subtracting 39 from 50.
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 13:
The number 13 fits into 110 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 70783.8461538
The remainder is 6 after subtracting 104 from 110.
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 14:
60 divided by 13 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 70783.84615384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 70783.84615384 and a remainder of 8e-09.
