83581134 ÷ 102 
The aim is to understand the frequency of 102 in 83581134.

Step 1:
When dividing 8 by 102, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 102

Advancing to step 2:
102 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (5) of the dividend behind the 83 and repeat the process: 835 / 102

Moving on to step 3:
102 can be fit into 835 8 times, resulting in a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 816 from 835 to get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 102

Moving on to step 4:
102 goes into 198 1 times with a remainder of 96.
Write down 1 as next digit of the result. 
Result so far: 81.0
Deduct 102 from 198 and we're left with 96.
Fetch the next digit (1) from the dividend, attach it to 96 and continue: 961 / 102

Moving on to step 5:
If we divide 961 by 102, we get 9 and a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 819.0
Subtract 918 from 961 to get 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 102

Step 6:
If we divide 431 by 102, we get 4 and a remainder of 23.
The next digit of our result is 4. 
Result so far: 8194.0
Deduct 408 from 431 and we're left with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 102

Moving on to step 7:
If we divide 233 by 102, we get 2 and a remainder of 29.
The next digit of our result is 2. 
Result so far: 81942.0
If we take 204 away from 233, we end up with 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 102

Advancing to step 8:
102 can be fit into 294 2 times, resulting in a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 819422.0
Deduct 204 from 294 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 9:
If we divide 900 by 102, we get 8 and a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 819422.8
Deduct 816 from 900 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
When dividing 840 by 102, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 819422.88
The remainder is 24 after subtracting 816 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 819422.88, with a leftover of 0.024.
