Let's divide 85484281 by 728
The aim is to understand the frequency of 728 in 85484281.

Advancing to step 1:
If we divide 8 by 728, 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.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 728

Step 2:
85 divided by 728 is 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Grab the next digit (4) from the dividend, add it to 85, then carry on: 854 / 728

Going ahead to step 3:
854 divided by 728 is 1 with a remainder of 126.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 728 from 854 and we're left with 126.
Bring next digit (8) of the dividend behind the 126 and repeat the process: 1268 / 728

Step 4:
728 goes into 1268 1 times with a remainder of 540.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 540 after subtracting 728 from 1268.
Bring next digit (4) of the dividend behind the 540 and repeat the process: 5404 / 728

Advancing to step 5:
5404 divided by 728 is 7 with a remainder of 308.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we take 5096 away from 5404, we end up with 308.
Append the next digit (2) from the dividend to 308 and continue with: 3082 / 728

Advancing to step 6:
If we divide 3082 by 728, we get 4 and a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 1174.0
The remainder is 170 after subtracting 2912 from 3082.
Grab the next digit (8) from the dividend, add it to 170, then carry on: 1708 / 728

Let's proceed to step 7:
The number 728 fits into 1708 2 times, leaving a remainder of 252.
Record the quotient 2 as the next digit in the result. 
Result so far: 11742.0
The remainder is 252 after subtracting 1456 from 1708.
Fetch the next digit (1) from the dividend, attach it to 252 and continue: 2521 / 728

Going ahead to step 8:
728 can be fit into 2521 3 times, resulting in a remainder of 337.
The next digit of our result is 3. 
Result so far: 117423.0
If we subtract 2184 from 2521, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Going ahead to step 9:
The number 728 fits into 3370 4 times, leaving a remainder of 458.
Use 4 as the next digit of our solution. 
Result so far: 117423.4
The remainder is 458 after subtracting 2912 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 10:
728 can be fit into 4580 6 times, resulting in a remainder of 212.
The next digit of our result is 6. 
Result so far: 117423.46
Subtracting 4368 from 4580 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 11:
728 goes into 2120 2 times with a remainder of 664.
The number 2 becomes the next digit in our result. 
Result so far: 117423.462
Subtracting 1456 from 2120 leaves us with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Moving on to step 12:
When dividing 6640 by 728, we get 9 with a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 117423.4629
If we subtract 6552 from 6640, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 13:
The number 728 fits into 880 1 times, leaving a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 117423.46291
Deduct 728 from 880 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 14:
The number 728 fits into 1520 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 117423.462912
The remainder is 64 after subtracting 1456 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
If we divide 640 by 728, we get 0 and a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 117423.462912
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 16:
728 goes into 6400 8 times with a remainder of 576.
Write down 8 as next digit of the result. 
Result so far: 117423.46291208
Deduct 5824 from 6400 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The quotient of the division is 117423.46291208, and the remainder is 5.76e-07.
