We divide 83142486 by 225
The aim is to understand the frequency of 225 in 83142486.

Step 1:
8 divided by 225 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 225

Let's proceed to step 2:
If we divide 83 by 225, we get 0 and a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Append the next digit (1) from the dividend to 83 and continue with: 831 / 225

Moving on to step 3:
If we divide 831 by 225, we get 3 and a remainder of 156.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 675 away from 831, we end up with 156.
Bring next digit (4) of the dividend behind the 156 and repeat the process: 1564 / 225

Step 4:
When dividing 1564 by 225, we get 6 with a remainder of 214.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 1350 from 1564 and we're left with 214.
Append the next digit (2) from the dividend to 214 and continue with: 2142 / 225

Going ahead to step 5:
If we divide 2142 by 225, we get 9 and a remainder of 117.
Write down 9 as next digit of the result. 
Result so far: 369.0
If we subtract 2025 from 2142, we get 117.
Include the next digit (4) from the dividend after 117, then repeat: 1174 / 225

On to step 6:
When dividing 1174 by 225, we get 5 with a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 3695.0
If we take 1125 away from 1174, we end up with 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 225

Going ahead to step 7:
498 divided by 225 is 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 36952.0
If we take 450 away from 498, we end up with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 225

On to step 8:
225 can be fit into 486 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 369522.0
Subtract 450 from 486 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
360 divided by 225 is 1 with a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 369522.1
Subtract 225 from 360 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 10:
When dividing 1350 by 225, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 369522.16
The remainder is 0 after subtracting 1350 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
225 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 369522.16
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
The number 225 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 369522.16
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 369522.16, with a leftover of 0.0.
