We look at the division of 158349 by 37 
The aim is to understand the frequency of 37 in 158349.

Advancing to step 1:
When dividing 1 by 37, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 37

Step 2:
If we divide 15 by 37, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 37

Let's proceed to step 3:
If we divide 158 by 37, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 148 from 158 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 37

Going ahead to step 4:
When dividing 103 by 37, we get 2 with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 74 from 103 leaves us with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 37

On to step 5:
37 goes into 294 7 times with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 427.0
Subtract 259 from 294 to get 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 37

Let's proceed to step 6:
359 divided by 37 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 4279.0
The remainder is 26 after subtracting 333 from 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
The number 37 fits into 260 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 4279.7
Subtract 259 from 260 to 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 8:
10 divided by 37 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 4279.7
If we take 0 away from 10, we end up with 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 9:
37 can be fit into 100 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 4279.702
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.

Going ahead to step 10:
260 divided by 37 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 4279.7027
Subtracting 259 from 260 leaves us 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.

Let's proceed to step 11:
10 divided by 37 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 4279.7027
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.

On to step 12:
100 divided by 37 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 4279.702702
Subtracting 74 from 100 leaves us 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.

On to step 13:
The number 37 fits into 260 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 4279.7027027
Deduct 259 from 260 and we're left 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 14:
37 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4279.7027027
Subtract 0 from 10 to 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.

In conclusion, the division gives 4279.7027027 with a balance of 1e-08.
