We look at the division of 233905 by 37 
The aim is to understand the frequency of 37 in 233905.

Let's proceed to step 1:
2 divided by 37 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 37

Moving on to step 2:
The number 37 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 37

Moving on to step 3:
When dividing 233 by 37, we get 6 with a remainder of 11.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 222 from 233 and we're left with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 37

Going ahead to step 4:
When dividing 119 by 37, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we take 111 away from 119, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 37

Moving on to step 5:
37 can be fit into 80 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 632.0
Deduct 74 from 80 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 37

Let's proceed to step 6:
65 divided by 37 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 6321.0
The remainder is 28 after subtracting 37 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
37 can be fit into 280 7 times, resulting in a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 6321.7
Subtracting 259 from 280 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
If we divide 210 by 37, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 6321.75
Subtract 185 from 210 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
37 can be fit into 250 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 6321.756
If we subtract 222 from 250, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
280 divided by 37 is 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 6321.7567
Subtract 259 from 280 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
The number 37 fits into 210 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6321.75675
If we take 185 away from 210, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
If we divide 250 by 37, we get 6 and a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 6321.756756
The remainder is 28 after subtracting 222 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
The number 37 fits into 280 7 times, leaving a remainder of 21.
The next digit of our result is 7. 
Result so far: 6321.7567567
If we subtract 259 from 280, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 14:
37 goes into 210 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6321.75675675
Deduct 185 from 210 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 6321.75675675 with a remaining 2.5e-08.
