69653172 divided by 720 
The aim is to understand the frequency of 720 in 69653172.

On to step 1:
The number 720 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 720

On to step 2:
720 can be fit into 69 0 times, resulting in a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Take the next digit (6) from the dividend and append it to 69, then repeat: 696 / 720

Going ahead to step 3:
When dividing 696 by 720, we get 0 with a remainder of 696.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 696 leaves us with 696.
Grab the next digit (5) from the dividend, add it to 696, then carry on: 6965 / 720

Advancing to step 4:
If we divide 6965 by 720, we get 9 and a remainder of 485.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 485 after subtracting 6480 from 6965.
Include the next digit (3) from the dividend after 485, then repeat: 4853 / 720

Advancing to step 5:
When dividing 4853 by 720, we get 6 with a remainder of 533.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Deduct 4320 from 4853 and we're left with 533.
Append the next digit (1) from the dividend to 533 and continue with: 5331 / 720

Moving on to step 6:
The number 720 fits into 5331 7 times, leaving a remainder of 291.
Write down 7 as next digit of the result. 
Result so far: 967.0
Deduct 5040 from 5331 and we're left with 291.
Bring next digit (7) of the dividend behind the 291 and repeat the process: 2917 / 720

On to step 7:
720 can be fit into 2917 4 times, resulting in a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 9674.0
Deduct 2880 from 2917 and we're left with 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 720

Step 8:
If we divide 372 by 720, we get 0 and a remainder of 372.
The number 0 becomes the next digit in our result. 
Result so far: 96740.0
The remainder is 372 after subtracting 0 from 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 9:
3720 divided by 720 is 5 with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 96740.5
If we take 3600 away from 3720, 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.

Moving on to step 10:
1200 divided by 720 is 1 with a remainder of 480.
The number 1 becomes the next digit in our result. 
Result so far: 96740.51
If we subtract 720 from 1200, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 11:
If we divide 4800 by 720, we get 6 and a remainder of 480.
The next digit of our result is 6. 
Result so far: 96740.516
Deduct 4320 from 4800 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
720 can be fit into 4800 6 times, resulting in a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 96740.5166
If we take 4320 away from 4800, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 96740.5166, with a leftover of 0.0048.
