5980201 ÷ 728 
The aim is to understand the frequency of 728 in 5980201.

Step 1:
5 divided by 728 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 728

Going ahead to step 2:
The number 728 fits into 59 0 times, leaving a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 728

On to step 3:
598 divided by 728 is 0 with a remainder of 598.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 598 to get 598.
Fetch the next digit (0) from the dividend, attach it to 598 and continue: 5980 / 728

Step 4:
If we divide 5980 by 728, we get 8 and a remainder of 156.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 156 after subtracting 5824 from 5980.
Bring next digit (2) of the dividend behind the 156 and repeat the process: 1562 / 728

Let's proceed to step 5:
If we divide 1562 by 728, we get 2 and a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Deduct 1456 from 1562 and we're left with 106.
Append the next digit (0) from the dividend to 106 and continue with: 1060 / 728

Going ahead to step 6:
728 goes into 1060 1 times with a remainder of 332.
The next digit of our result is 1. 
Result so far: 821.0
The remainder is 332 after subtracting 728 from 1060.
Bring next digit (1) of the dividend behind the 332 and repeat the process: 3321 / 728

Advancing to step 7:
728 goes into 3321 4 times with a remainder of 409.
Record the quotient 4 as the next digit in the result. 
Result so far: 8214.0
If we subtract 2912 from 3321, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 8:
4090 divided by 728 is 5 with a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 8214.5
If we subtract 3640 from 4090, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 9:
When dividing 4500 by 728, we get 6 with a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 8214.56
The remainder is 132 after subtracting 4368 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 10:
If we divide 1320 by 728, we get 1 and a remainder of 592.
Put 1 as the next digit of the answer. 
Result so far: 8214.561
If we subtract 728 from 1320, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 11:
5920 divided by 728 is 8 with a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 8214.5618
The remainder is 96 after subtracting 5824 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 12:
The number 728 fits into 960 1 times, leaving a remainder of 232.
Use 1 as the next digit of our solution. 
Result so far: 8214.56181
If we take 728 away from 960, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 13:
728 goes into 2320 3 times with a remainder of 136.
Write down 3 as next digit of the result. 
Result so far: 8214.561813
If we take 2184 away from 2320, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 14:
If we divide 1360 by 728, we get 1 and a remainder of 632.
The number 1 becomes the next digit in our result. 
Result so far: 8214.5618131
Deduct 728 from 1360 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Moving on to step 15:
6320 divided by 728 is 8 with a remainder of 496.
Write down 8 as next digit of the result. 
Result so far: 8214.56181318
The remainder is 496 after subtracting 5824 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

After the division, we end up with 8214.56181318 and a remainder of 4.96e-07.
