81204068 ÷ 480 
The aim is to understand the frequency of 480 in 81204068.

Moving on to step 1:
8 divided by 480 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 480

Advancing to step 2:
480 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 480

Step 3:
If we divide 812 by 480, we get 1 and a remainder of 332.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 480 from 812 leaves us with 332.
Include the next digit (0) from the dividend after 332, then repeat: 3320 / 480

Step 4:
3320 divided by 480 is 6 with a remainder of 440.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 440 after subtracting 2880 from 3320.
Include the next digit (4) from the dividend after 440, then repeat: 4404 / 480

Going ahead to step 5:
The number 480 fits into 4404 9 times, leaving a remainder of 84.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
Subtracting 4320 from 4404 leaves us with 84.
Fetch the next digit (0) from the dividend, attach it to 84 and continue: 840 / 480

On to step 6:
480 can be fit into 840 1 times, resulting in a remainder of 360.
Record the quotient 1 as the next digit in the result. 
Result so far: 1691.0
If we take 480 away from 840, we end up with 360.
Grab the next digit (6) from the dividend, add it to 360, then carry on: 3606 / 480

Let's proceed to step 7:
480 can be fit into 3606 7 times, resulting in a remainder of 246.
The next digit of our result is 7. 
Result so far: 16917.0
Deduct 3360 from 3606 and we're left with 246.
Append the next digit (8) from the dividend to 246 and continue with: 2468 / 480

Step 8:
480 goes into 2468 5 times with a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 169175.0
If we subtract 2400 from 2468, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
The number 480 fits into 680 1 times, leaving a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 169175.1
Subtract 480 from 680 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
480 goes into 2000 4 times with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 169175.14
Subtract 1920 from 2000 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
800 divided by 480 is 1 with a remainder of 320.
Write down 1 as next digit of the result. 
Result so far: 169175.141
Deduct 480 from 800 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
3200 divided by 480 is 6 with a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 169175.1416
Subtract 2880 from 3200 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 13:
The number 480 fits into 3200 6 times, leaving a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 169175.14166
Deduct 2880 from 3200 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 169175.14166 with a remainder of 0.00032.
