We look at the division of 72908 by 37 
The aim is to understand the frequency of 37 in 72908.

Let's proceed to step 1:
When dividing 7 by 37, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 37

On to step 2:
If we divide 72 by 37, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 37 from 72 and we're left with 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 37

Going ahead to step 3:
When dividing 359 by 37, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 333 from 359, we get 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 37

Moving on to step 4:
When dividing 260 by 37, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 197.0
The remainder is 1 after subtracting 259 from 260.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 37

Advancing to step 5:
When dividing 18 by 37, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 1970.0
The remainder is 18 after subtracting 0 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 6:
When dividing 180 by 37, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 1970.4
If we take 148 away from 180, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
If we divide 320 by 37, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 1970.48
If we take 296 away from 320, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
The number 37 fits into 240 6 times, leaving a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 1970.486
Subtracting 222 from 240 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
If we divide 180 by 37, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 1970.4864
Subtract 148 from 180 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
When dividing 320 by 37, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 1970.48648
Subtracting 296 from 320 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
37 can be fit into 240 6 times, resulting in a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 1970.486486
Subtract 222 from 240 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
The number 37 fits into 180 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 1970.4864864
If we take 148 away from 180, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
If we divide 320 by 37, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1970.48648648
If we subtract 296 from 320, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 1970.48648648, and the remainder is 2.4e-08.
