We look at the division of 257320 by 37 
The aim is to understand the frequency of 37 in 257320.

Advancing to step 1:
37 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 37

Moving on to step 2:
When dividing 25 by 37, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 37

Advancing to step 3:
The number 37 fits into 257 6 times, leaving a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 222 away from 257, we end up with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 37

Let's proceed to step 4:
353 divided by 37 is 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 69.0
If we take 333 away from 353, we end up with 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 37

Let's proceed to step 5:
When dividing 202 by 37, we get 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 695.0
Subtracting 185 from 202 leaves us with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 37

Advancing to step 6:
170 divided by 37 is 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 6954.0
Subtract 148 from 170 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
The number 37 fits into 220 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 6954.5
If we take 185 away from 220, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
The number 37 fits into 350 9 times, leaving a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 6954.59
If we take 333 away from 350, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
170 divided by 37 is 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 6954.594
Deduct 148 from 170 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
37 can be fit into 220 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 6954.5945
Subtract 185 from 220 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
350 divided by 37 is 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 6954.59459
If we subtract 333 from 350, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
37 goes into 170 4 times with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 6954.594594
The remainder is 22 after subtracting 148 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
The number 37 fits into 220 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 6954.5945945
Subtracting 185 from 220 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
37 can be fit into 350 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 6954.59459459
If we subtract 333 from 350, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 6954.59459459, with a leftover of 1.7e-08.
