We look at the division of 355124 by 37 
The aim is to understand the frequency of 37 in 355124.

Moving on to step 1:
If we divide 3 by 37, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 37

Advancing to step 2:
37 can be fit into 35 0 times, resulting in a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 37

Advancing to step 3:
If we divide 355 by 37, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 333 from 355 to get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 37

Let's proceed to step 4:
37 can be fit into 221 5 times, resulting in a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Subtract 185 from 221 to get 36.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 37

Going ahead to step 5:
When dividing 362 by 37, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 959.0
Subtract 333 from 362 to get 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 37

Going ahead to step 6:
When dividing 294 by 37, we get 7 with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 9597.0
Deduct 259 from 294 and we're left 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.

Step 7:
When dividing 350 by 37, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 9597.9
The remainder is 17 after subtracting 333 from 350.
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 8:
170 divided by 37 is 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 9597.94
If we take 148 away from 170, we end up 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.

Going ahead to step 9:
37 goes into 220 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 9597.945
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.

Moving on to step 10:
If we divide 350 by 37, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 9597.9459
Subtract 333 from 350 to 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.

On to step 11:
37 goes into 170 4 times with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 9597.94594
Subtracting 148 from 170 leaves us 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.

Advancing to step 12:
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: 9597.945945
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.

Advancing to step 13:
350 divided by 37 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 9597.9459459
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.

Step 14:
If we divide 170 by 37, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 9597.94594594
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.

The final outcome is 9597.94594594, with a leftover of 2.2e-08.
