We're dividing 80395509 by 158 
The aim is to understand the frequency of 158 in 80395509.

Going ahead to step 1:
If we divide 8 by 158, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 158

On to step 2:
When dividing 80 by 158, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 158

Moving on to step 3:
158 goes into 803 5 times with a remainder of 13.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 790 from 803 leaves us with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 158

Advancing to step 4:
If we divide 139 by 158, we get 0 and a remainder of 139.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we subtract 0 from 139, we get 139.
Bring next digit (5) of the dividend behind the 139 and repeat the process: 1395 / 158

On to step 5:
158 goes into 1395 8 times with a remainder of 131.
The next digit of our result is 8. 
Result so far: 508.0
If we subtract 1264 from 1395, we get 131.
Append the next digit (5) from the dividend to 131 and continue with: 1315 / 158

Let's proceed to step 6:
158 goes into 1315 8 times with a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 5088.0
If we subtract 1264 from 1315, we get 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 158

Let's proceed to step 7:
158 goes into 510 3 times with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 50883.0
If we take 474 away from 510, we end up with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 158

Advancing to step 8:
158 can be fit into 369 2 times, resulting in a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 508832.0
Subtract 316 from 369 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
When dividing 530 by 158, we get 3 with a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 508832.3
If we subtract 474 from 530, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
560 divided by 158 is 3 with a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 508832.33
If we take 474 away from 560, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 508832.33 with a balance of 0.086.
