We look at the division of 36409990 by 235 
The aim is to understand the frequency of 235 in 36409990.

Let's proceed to step 1:
When dividing 3 by 235, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 235

Let's proceed to step 2:
When dividing 36 by 235, we get 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 235

Let's proceed to step 3:
364 divided by 235 is 1 with a remainder of 129.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 235 from 364 leaves us with 129.
Include the next digit (0) from the dividend after 129, then repeat: 1290 / 235

Going ahead to step 4:
1290 divided by 235 is 5 with a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 1175 from 1290, we get 115.
Include the next digit (9) from the dividend after 115, then repeat: 1159 / 235

Step 5:
235 can be fit into 1159 4 times, resulting in a remainder of 219.
Use 4 as the next digit of our solution. 
Result so far: 154.0
If we subtract 940 from 1159, we get 219.
Include the next digit (9) from the dividend after 219, then repeat: 2199 / 235

Moving on to step 6:
When dividing 2199 by 235, we get 9 with a remainder of 84.
Write down 9 as next digit of the result. 
Result so far: 1549.0
Deduct 2115 from 2199 and we're left with 84.
Grab the next digit (9) from the dividend, add it to 84, then carry on: 849 / 235

Let's proceed to step 7:
The number 235 fits into 849 3 times, leaving a remainder of 144.
The number 3 becomes the next digit in our result. 
Result so far: 15493.0
If we subtract 705 from 849, we get 144.
Take the next digit (0) from the dividend and append it to 144, then repeat: 1440 / 235

Advancing to step 8:
235 can be fit into 1440 6 times, resulting in a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 154936.0
If we take 1410 away from 1440, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
The number 235 fits into 300 1 times, leaving a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 154936.1
Subtract 235 from 300 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
When dividing 650 by 235, we get 2 with a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 154936.12
If we take 470 away from 650, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
235 can be fit into 1800 7 times, resulting in a remainder of 155.
Write down 7 as next digit of the result. 
Result so far: 154936.127
The remainder is 155 after subtracting 1645 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 12:
The number 235 fits into 1550 6 times, leaving a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 154936.1276
If we subtract 1410 from 1550, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 13:
If we divide 1400 by 235, we get 5 and a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 154936.12765
Subtracting 1175 from 1400 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 14:
The number 235 fits into 2250 9 times, leaving a remainder of 135.
Use 9 as the next digit of our solution. 
Result so far: 154936.127659
Subtracting 2115 from 2250 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 15:
235 can be fit into 1350 5 times, resulting in a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 154936.1276595
Subtract 1175 from 1350 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 16:
When dividing 1750 by 235, we get 7 with a remainder of 105.
The number 7 becomes the next digit in our result. 
Result so far: 154936.12765957
Subtracting 1645 from 1750 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

In conclusion, the division gives 154936.12765957 with a balance of 1.05e-07.
