97225572 ÷ 902 
The aim is to understand the frequency of 902 in 97225572.

Let's proceed to step 1:
902 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 902

Let's proceed to step 2:
If we divide 97 by 902, we get 0 and a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Take the next digit (2) from the dividend and append it to 97, then repeat: 972 / 902

On to step 3:
902 can be fit into 972 1 times, resulting in a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 70 after subtracting 902 from 972.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 902

Moving on to step 4:
If we divide 702 by 902, we get 0 and a remainder of 702.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 702 leaves us with 702.
Include the next digit (5) from the dividend after 702, then repeat: 7025 / 902

Moving on to step 5:
7025 divided by 902 is 7 with a remainder of 711.
Use 7 as the next digit of our solution. 
Result so far: 107.0
The remainder is 711 after subtracting 6314 from 7025.
Grab the next digit (5) from the dividend, add it to 711, then carry on: 7115 / 902

On to step 6:
902 goes into 7115 7 times with a remainder of 801.
Record the quotient 7 as the next digit in the result. 
Result so far: 1077.0
Subtracting 6314 from 7115 leaves us with 801.
Include the next digit (7) from the dividend after 801, then repeat: 8017 / 902

On to step 7:
902 can be fit into 8017 8 times, resulting in a remainder of 801.
The number 8 becomes the next digit in our result. 
Result so far: 10778.0
If we take 7216 away from 8017, we end up with 801.
Include the next digit (2) from the dividend after 801, then repeat: 8012 / 902

Step 8:
If we divide 8012 by 902, we get 8 and a remainder of 796.
Write down 8 as next digit of the result. 
Result so far: 107788.0
The remainder is 796 after subtracting 7216 from 8012.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

On to step 9:
The number 902 fits into 7960 8 times, leaving a remainder of 744.
The next digit of our result is 8. 
Result so far: 107788.8
If we subtract 7216 from 7960, we get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Moving on to step 10:
If we divide 7440 by 902, we get 8 and a remainder of 224.
Use 8 as the next digit of our solution. 
Result so far: 107788.88
If we take 7216 away from 7440, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

In conclusion, the division gives 107788.88 with a balance of 0.224.
