91472597 ÷ 204 
The aim is to understand the frequency of 204 in 91472597.

On to step 1:
When dividing 9 by 204, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 204

Going ahead to step 2:
91 divided by 204 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (4) from the dividend to 91 and continue with: 914 / 204

Moving on to step 3:
204 goes into 914 4 times with a remainder of 98.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 98 after subtracting 816 from 914.
Bring next digit (7) of the dividend behind the 98 and repeat the process: 987 / 204

Step 4:
204 goes into 987 4 times with a remainder of 171.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 171 after subtracting 816 from 987.
Append the next digit (2) from the dividend to 171 and continue with: 1712 / 204

Step 5:
If we divide 1712 by 204, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 448.0
Subtracting 1632 from 1712 leaves us with 80.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 204

Advancing to step 6:
204 goes into 805 3 times with a remainder of 193.
The next digit of our result is 3. 
Result so far: 4483.0
Deduct 612 from 805 and we're left with 193.
Take the next digit (9) from the dividend and append it to 193, then repeat: 1939 / 204

Advancing to step 7:
1939 divided by 204 is 9 with a remainder of 103.
The next digit of our result is 9. 
Result so far: 44839.0
If we subtract 1836 from 1939, we get 103.
Append the next digit (7) from the dividend to 103 and continue with: 1037 / 204

Going ahead to step 8:
1037 divided by 204 is 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 448395.0
Deduct 1020 from 1037 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
204 can be fit into 170 0 times, resulting in a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 448395.0
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
When dividing 1700 by 204, we get 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 448395.08
Deduct 1632 from 1700 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
If we divide 680 by 204, we get 3 and a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 448395.083
If we subtract 612 from 680, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 12:
204 can be fit into 680 3 times, resulting in a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 448395.0833
Deduct 612 from 680 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 448395.0833, with a leftover of 0.00068.
