We divide 87828803 by 145
The aim is to understand the frequency of 145 in 87828803.

Moving on to step 1:
When dividing 8 by 145, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 145

Moving on to step 2:
If we divide 87 by 145, we get 0 and a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 145

Step 3:
878 divided by 145 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 870 away from 878, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 145

On to step 4:
82 divided by 145 is 0 with a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
The remainder is 82 after subtracting 0 from 82.
Include the next digit (8) from the dividend after 82, then repeat: 828 / 145

Let's proceed to step 5:
145 goes into 828 5 times with a remainder of 103.
Write down 5 as next digit of the result. 
Result so far: 605.0
Subtract 725 from 828 to get 103.
Include the next digit (8) from the dividend after 103, then repeat: 1038 / 145

On to step 6:
When dividing 1038 by 145, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 6057.0
Subtract 1015 from 1038 to get 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 145

Advancing to step 7:
When dividing 230 by 145, we get 1 with a remainder of 85.
Record the quotient 1 as the next digit in the result. 
Result so far: 60571.0
Subtract 145 from 230 to get 85.
Bring next digit (3) of the dividend behind the 85 and repeat the process: 853 / 145

Moving on to step 8:
The number 145 fits into 853 5 times, leaving a remainder of 128.
Write down 5 as next digit of the result. 
Result so far: 605715.0
If we take 725 away from 853, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 9:
If we divide 1280 by 145, we get 8 and a remainder of 120.
The next digit of our result is 8. 
Result so far: 605715.8
If we take 1160 away from 1280, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
The number 145 fits into 1200 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 605715.88
Subtract 1160 from 1200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 605715.88, with a leftover of 0.04.
