We look at the division of 13236803 by 37 
The aim is to understand the frequency of 37 in 13236803.

Going ahead to step 1:
The number 37 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 37

Let's proceed to step 2:
The number 37 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 37

Going ahead to step 3:
If we divide 132 by 37, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 21 after subtracting 111 from 132.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 37

Let's proceed to step 4:
37 goes into 213 5 times with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtracting 185 from 213 leaves us with 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 37

Let's proceed to step 5:
The number 37 fits into 286 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 357.0
If we take 259 away from 286, we end up with 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 37

Step 6:
The number 37 fits into 278 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 3577.0
Subtract 259 from 278 to get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 37

Moving on to step 7:
When dividing 190 by 37, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 35775.0
The remainder is 5 after subtracting 185 from 190.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 37

Advancing to step 8:
37 can be fit into 53 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 357751.0
If we subtract 37 from 53, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
The number 37 fits into 160 4 times, leaving a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 357751.4
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.

Let's proceed to step 10:
120 divided by 37 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 357751.43
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.

Moving on to step 11:
37 can be fit into 90 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 357751.432
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 12:
If we divide 160 by 37, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 357751.4324
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.

Moving on to step 13:
If we divide 120 by 37, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 357751.43243
The remainder is 9 after subtracting 111 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
If we divide 90 by 37, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 357751.432432
Deduct 74 from 90 and we're left 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 15:
The number 37 fits into 160 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 357751.4324324
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.

Let's proceed to step 16:
When dividing 120 by 37, we get 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 357751.43243243
If we take 111 away from 120, we end up 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.

After the division, we end up with 357751.43243243 and a remainder of 9e-09.
