We're dividing 70706838 by 728 
The aim is to understand the frequency of 728 in 70706838.

Step 1:
728 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 728

On to step 2:
If we divide 70 by 728, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 728

Let's proceed to step 3:
707 divided by 728 is 0 with a remainder of 707.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 707 to get 707.
Append the next digit (0) from the dividend to 707 and continue with: 7070 / 728

Moving on to step 4:
The number 728 fits into 7070 9 times, leaving a remainder of 518.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 518 after subtracting 6552 from 7070.
Take the next digit (6) from the dividend and append it to 518, then repeat: 5186 / 728

Advancing to step 5:
728 goes into 5186 7 times with a remainder of 90.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
If we subtract 5096 from 5186, we get 90.
Grab the next digit (8) from the dividend, add it to 90, then carry on: 908 / 728

Advancing to step 6:
728 can be fit into 908 1 times, resulting in a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 971.0
Subtract 728 from 908 to get 180.
Fetch the next digit (3) from the dividend, attach it to 180 and continue: 1803 / 728

Step 7:
1803 divided by 728 is 2 with a remainder of 347.
The next digit of our result is 2. 
Result so far: 9712.0
Deduct 1456 from 1803 and we're left with 347.
Take the next digit (8) from the dividend and append it to 347, then repeat: 3478 / 728

Step 8:
When dividing 3478 by 728, we get 4 with a remainder of 566.
The number 4 becomes the next digit in our result. 
Result so far: 97124.0
If we take 2912 away from 3478, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 9:
728 can be fit into 5660 7 times, resulting in a remainder of 564.
Use 7 as the next digit of our solution. 
Result so far: 97124.7
The remainder is 564 after subtracting 5096 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Advancing to step 10:
When dividing 5640 by 728, we get 7 with a remainder of 544.
The next digit of our result is 7. 
Result so far: 97124.77
Subtract 5096 from 5640 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The quotient of the division is 97124.77, and the remainder is 0.544.
