80746376 divided by 728 
The aim is to understand the frequency of 728 in 80746376.

Step 1:
When dividing 8 by 728, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 728

Step 2:
728 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 728

Let's proceed to step 3:
The number 728 fits into 807 1 times, leaving a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 728 from 807 and we're left with 79.
Take the next digit (4) from the dividend and append it to 79, then repeat: 794 / 728

On to step 4:
794 divided by 728 is 1 with a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 728 from 794 and we're left with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 728

Advancing to step 5:
666 divided by 728 is 0 with a remainder of 666.
Put 0 as the next digit of the answer. 
Result so far: 110.0
If we take 0 away from 666, we end up with 666.
Bring next digit (3) of the dividend behind the 666 and repeat the process: 6663 / 728

Going ahead to step 6:
728 can be fit into 6663 9 times, resulting in a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 1109.0
Subtract 6552 from 6663 to get 111.
Take the next digit (7) from the dividend and append it to 111, then repeat: 1117 / 728

Advancing to step 7:
728 can be fit into 1117 1 times, resulting in a remainder of 389.
The number 1 becomes the next digit in our result. 
Result so far: 11091.0
Subtract 728 from 1117 to get 389.
Grab the next digit (6) from the dividend, add it to 389, then carry on: 3896 / 728

Going ahead to step 8:
728 goes into 3896 5 times with a remainder of 256.
Put 5 as the next digit of the answer. 
Result so far: 110915.0
If we subtract 3640 from 3896, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 9:
728 goes into 2560 3 times with a remainder of 376.
Write down 3 as next digit of the result. 
Result so far: 110915.3
Subtract 2184 from 2560 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 10:
728 can be fit into 3760 5 times, resulting in a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 110915.35
Subtract 3640 from 3760 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 11:
728 can be fit into 1200 1 times, resulting in a remainder of 472.
The next digit of our result is 1. 
Result so far: 110915.351
Subtracting 728 from 1200 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 12:
When dividing 4720 by 728, we get 6 with a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 110915.3516
If we take 4368 away from 4720, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 13:
The number 728 fits into 3520 4 times, leaving a remainder of 608.
Put 4 as the next digit of the answer. 
Result so far: 110915.35164
Subtract 2912 from 3520 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 14:
728 can be fit into 6080 8 times, resulting in a remainder of 256.
The next digit of our result is 8. 
Result so far: 110915.351648
If we take 5824 away from 6080, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 15:
When dividing 2560 by 728, we get 3 with a remainder of 376.
The number 3 becomes the next digit in our result. 
Result so far: 110915.3516483
Deduct 2184 from 2560 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 16:
The number 728 fits into 3760 5 times, leaving a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 110915.35164835
If we take 3640 away from 3760, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 110915.35164835 and a remainder of 1.2e-07.
