We look at the division of 318528 by 37 
The aim is to understand the frequency of 37 in 318528.

Going ahead to step 1:
If we divide 3 by 37, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 37

Moving on to step 2:
37 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 37

Moving on to step 3:
If we divide 318 by 37, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 296 from 318 and we're left with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 37

Advancing to step 4:
37 goes into 225 6 times with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtract 222 from 225 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 37

Moving on to step 5:
When dividing 32 by 37, we get 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 860.0
Subtracting 0 from 32 leaves us with 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 37

On to step 6:
37 can be fit into 328 8 times, resulting in a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 8608.0
If we take 296 away from 328, 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.

Moving on to 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: 8608.8
Subtract 296 from 320 to 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.

Let's proceed to step 8:
The number 37 fits into 240 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 8608.86
If we subtract 222 from 240, we 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.

On to step 9:
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: 8608.864
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.

Let's proceed to step 10:
37 can be fit into 320 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 8608.8648
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.

Let's proceed to step 11:
240 divided by 37 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 8608.86486
If we subtract 222 from 240, we 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.

On to step 12:
The number 37 fits into 180 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 8608.864864
The remainder is 32 after subtracting 148 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
37 can be fit into 320 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 8608.8648648
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 14:
37 goes into 240 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 8608.86486486
Deduct 222 from 240 and we're left 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.

The final outcome is 8608.86486486, with a leftover of 1.8e-08.
