We're dividing 72047050 by 728 
The aim is to understand the frequency of 728 in 72047050.

On to step 1:
When dividing 7 by 728, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 728

On to step 2:
If we divide 72 by 728, we get 0 and a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 728

Going ahead to step 3:
728 can be fit into 720 0 times, resulting in a remainder of 720.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 720 and we're left with 720.
Take the next digit (4) from the dividend and append it to 720, then repeat: 7204 / 728

Moving on to step 4:
If we divide 7204 by 728, we get 9 and a remainder of 652.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 652 after subtracting 6552 from 7204.
Bring next digit (7) of the dividend behind the 652 and repeat the process: 6527 / 728

Let's proceed to step 5:
When dividing 6527 by 728, we get 8 with a remainder of 703.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we subtract 5824 from 6527, we get 703.
Include the next digit (0) from the dividend after 703, then repeat: 7030 / 728

Let's proceed to step 6:
728 can be fit into 7030 9 times, resulting in a remainder of 478.
Write down 9 as next digit of the result. 
Result so far: 989.0
If we subtract 6552 from 7030, we get 478.
Grab the next digit (5) from the dividend, add it to 478, then carry on: 4785 / 728

Let's proceed to step 7:
728 can be fit into 4785 6 times, resulting in a remainder of 417.
Write down 6 as next digit of the result. 
Result so far: 9896.0
Subtract 4368 from 4785 to get 417.
Fetch the next digit (0) from the dividend, attach it to 417 and continue: 4170 / 728

Moving on to step 8:
728 can be fit into 4170 5 times, resulting in a remainder of 530.
Put 5 as the next digit of the answer. 
Result so far: 98965.0
Subtracting 3640 from 4170 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 9:
When dividing 5300 by 728, we get 7 with a remainder of 204.
Put 7 as the next digit of the answer. 
Result so far: 98965.7
The remainder is 204 after subtracting 5096 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 10:
2040 divided by 728 is 2 with a remainder of 584.
Write down 2 as next digit of the result. 
Result so far: 98965.72
If we subtract 1456 from 2040, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 11:
The number 728 fits into 5840 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 98965.728
Subtract 5824 from 5840 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
The number 728 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 98965.728
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
The number 728 fits into 1600 2 times, leaving a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 98965.72802
If we take 1456 away from 1600, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 14:
728 can be fit into 1440 1 times, resulting in a remainder of 712.
Use 1 as the next digit of our solution. 
Result so far: 98965.728021
Subtracting 728 from 1440 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Let's proceed to step 15:
If we divide 7120 by 728, we get 9 and a remainder of 568.
Use 9 as the next digit of our solution. 
Result so far: 98965.7280219
Subtracting 6552 from 7120 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 16:
If we divide 5680 by 728, we get 7 and a remainder of 584.
Record the quotient 7 as the next digit in the result. 
Result so far: 98965.72802197
The remainder is 584 after subtracting 5096 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

The final result is 98965.72802197 with a remainder of 5.84e-07.
