69542150 divided by 225 
The aim is to understand the frequency of 225 in 69542150.

On to step 1:
The number 225 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 225

On to step 2:
If we divide 69 by 225, we get 0 and a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Bring next digit (5) of the dividend behind the 69 and repeat the process: 695 / 225

Going ahead to step 3:
If we divide 695 by 225, we get 3 and a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 20 after subtracting 675 from 695.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 225

Going ahead to step 4:
204 divided by 225 is 0 with a remainder of 204.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 204 to get 204.
Bring next digit (2) of the dividend behind the 204 and repeat the process: 2042 / 225

Advancing to step 5:
225 can be fit into 2042 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 309.0
Deduct 2025 from 2042 and we're left with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 225

Step 6:
The number 225 fits into 171 0 times, leaving a remainder of 171.
Record the quotient 0 as the next digit in the result. 
Result so far: 3090.0
The remainder is 171 after subtracting 0 from 171.
Fetch the next digit (5) from the dividend, attach it to 171 and continue: 1715 / 225

On to step 7:
225 goes into 1715 7 times with a remainder of 140.
The number 7 becomes the next digit in our result. 
Result so far: 30907.0
Deduct 1575 from 1715 and we're left with 140.
Append the next digit (0) from the dividend to 140 and continue with: 1400 / 225

Going ahead to step 8:
225 can be fit into 1400 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 309076.0
The remainder is 50 after subtracting 1350 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
The number 225 fits into 500 2 times, leaving a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 309076.2
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
When dividing 500 by 225, we get 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 309076.22
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 309076.22 with a balance of 0.05.
