We're dividing 852889 by 37 
The aim is to understand the frequency of 37 in 852889.

On to step 1:
When dividing 8 by 37, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 37

Let's proceed to step 2:
If we divide 85 by 37, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 74 from 85, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 37

Moving on to step 3:
The number 37 fits into 112 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 111 from 112 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 37

Moving on to step 4:
When dividing 18 by 37, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 37

Advancing to step 5:
37 can be fit into 188 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 2305.0
If we subtract 185 from 188, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 37

Step 6:
37 goes into 39 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 23051.0
Subtract 37 from 39 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 37, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 23051.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 37, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 23051.05
Subtracting 185 from 200 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
When dividing 150 by 37, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 23051.054
The remainder is 2 after subtracting 148 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
37 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 23051.054
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
37 can be fit into 200 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 23051.05405
If we take 185 away from 200, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
37 can be fit into 150 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 23051.054054
If we subtract 148 from 150, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
37 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 23051.054054
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
200 divided by 37 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 23051.05405405
Deduct 185 from 200 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 23051.05405405, with a leftover of 1.5e-08.
