81704605 ÷ 153 
The aim is to understand the frequency of 153 in 81704605.

On to step 1:
If we divide 8 by 153, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 153

Moving on to step 2:
153 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 153

Moving on to step 3:
When dividing 817 by 153, we get 5 with a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 52 after subtracting 765 from 817.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 153

Let's proceed to step 4:
The number 153 fits into 520 3 times, leaving a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 459 from 520 leaves us with 61.
Take the next digit (4) from the dividend and append it to 61, then repeat: 614 / 153

Going ahead to step 5:
153 goes into 614 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 534.0
Subtract 612 from 614 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 153

Let's proceed to step 6:
When dividing 26 by 153, we get 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 5340.0
If we take 0 away from 26, we end up with 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 153

On to step 7:
When dividing 260 by 153, we get 1 with a remainder of 107.
Write down 1 as next digit of the result. 
Result so far: 53401.0
The remainder is 107 after subtracting 153 from 260.
Bring next digit (5) of the dividend behind the 107 and repeat the process: 1075 / 153

On to step 8:
The number 153 fits into 1075 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 534017.0
Subtracting 1071 from 1075 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
153 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 534017.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
153 can be fit into 400 2 times, resulting in a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 534017.02
Subtract 306 from 400 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 11:
940 divided by 153 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 534017.026
If we take 918 away from 940, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
When dividing 220 by 153, we get 1 with a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 534017.0261
Deduct 153 from 220 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 13:
If we divide 670 by 153, we get 4 and a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 534017.02614
The remainder is 58 after subtracting 612 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 14:
580 divided by 153 is 3 with a remainder of 121.
The next digit of our result is 3. 
Result so far: 534017.026143
Subtracting 459 from 580 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 15:
153 goes into 1210 7 times with a remainder of 139.
Put 7 as the next digit of the answer. 
Result so far: 534017.0261437
Deduct 1071 from 1210 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 16:
153 goes into 1390 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 534017.02614379
Deduct 1377 from 1390 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 534017.02614379 with a balance of 1.3e-08.
