We're dividing 523525 by 37 
The aim is to understand the frequency of 37 in 523525.

Step 1:
5 divided by 37 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 37

Going ahead to step 2:
37 goes into 52 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 37 from 52 to get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 37

On to step 3:
When dividing 153 by 37, we get 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 5 after subtracting 148 from 153.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 37

Step 4:
55 divided by 37 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 141.0
The remainder is 18 after subtracting 37 from 55.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 37

Let's proceed to step 5:
182 divided by 37 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 1414.0
If we subtract 148 from 182, we get 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 37

Let's proceed to step 6:
The number 37 fits into 345 9 times, leaving a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 14149.0
If we take 333 away from 345, we end up 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 7:
120 divided by 37 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 14149.3
Subtracting 111 from 120 leaves us with 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 8:
If we divide 90 by 37, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 14149.32
Subtracting 74 from 90 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
37 goes into 160 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 14149.324
If we take 148 away from 160, we end up 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.

Going ahead to step 10:
When dividing 120 by 37, we get 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 14149.3243
Subtracting 111 from 120 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
When dividing 90 by 37, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 14149.32432
If we take 74 away from 90, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
37 can be fit into 160 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 14149.324324
Subtract 148 from 160 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
37 can be fit into 120 3 times, resulting in a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 14149.3243243
Subtract 111 from 120 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.

Let's proceed to step 14:
90 divided by 37 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 14149.32432432
Subtracting 74 from 90 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 14149.32432432, with a leftover of 1.6e-08.
