Let's divide 937550 by 13
The aim is to understand the frequency of 13 in 937550.

Moving on to step 1:
The number 13 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 13

Step 2:
The number 13 fits into 93 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 91 from 93 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 13

Step 3:
When dividing 27 by 13, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 72.0
If we take 26 away from 27, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 13

On to step 4:
If we divide 15 by 13, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 721.0
Subtracting 13 from 15 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 13

Let's proceed to step 5:
If we divide 25 by 13, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 7211.0
If we subtract 13 from 25, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 13

Advancing to step 6:
If we divide 120 by 13, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 72119.0
If we subtract 117 from 120, we 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.

Let's proceed to step 7:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 72119.2
Subtracting 26 from 30 leaves us 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.

Step 8:
If we divide 40 by 13, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 72119.23
Subtracting 39 from 40 leaves us 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.

On to step 9:
The number 13 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 72119.23
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
If we divide 100 by 13, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 72119.2307
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
If we divide 90 by 13, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 72119.23076
Subtracting 78 from 90 leaves us 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.

Let's proceed to step 12:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 72119.230769
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
30 divided by 13 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 72119.2307692
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 72119.23076923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 72119.23076923, and the remainder is 1e-09.
