We look at the division of 853665 by 37 
The aim is to understand the frequency of 37 in 853665.

Advancing to step 1:
When dividing 8 by 37, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 37

On to step 2:
85 divided by 37 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 74 away from 85, we end up with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 37

Moving on to step 3:
The number 37 fits into 113 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 111 from 113 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 37

Moving on to step 4:
If we divide 26 by 37, we get 0 and a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
Deduct 0 from 26 and we're left with 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 37

Going ahead to step 5:
The number 37 fits into 266 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 2307.0
Subtracting 259 from 266 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 37

Step 6:
37 can be fit into 75 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 23072.0
If we take 74 away from 75, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 37, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 23072.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 37, we get 2 and a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 23072.02
If we subtract 74 from 100, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
If we divide 260 by 37, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 23072.027
If we subtract 259 from 260, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
If we divide 10 by 37, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 23072.027
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
100 divided by 37 is 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 23072.02702
If we take 74 away from 100, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
When dividing 260 by 37, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 23072.027027
The remainder is 1 after subtracting 259 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
When dividing 10 by 37, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 23072.027027
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
If we divide 100 by 37, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 23072.02702702
Subtract 74 from 100 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 23072.02702702 and a remainder of 2.6e-08.
