30388304 ÷ 486 
The aim is to understand the frequency of 486 in 30388304.

Going ahead to step 1:
If we divide 3 by 486, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 486

Advancing to step 2:
486 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 486

On to step 3:
When dividing 303 by 486, we get 0 with a remainder of 303.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 303 leaves us with 303.
Grab the next digit (8) from the dividend, add it to 303, then carry on: 3038 / 486

Moving on to step 4:
When dividing 3038 by 486, we get 6 with a remainder of 122.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 2916 from 3038 to get 122.
Include the next digit (8) from the dividend after 122, then repeat: 1228 / 486

Advancing to step 5:
When dividing 1228 by 486, we get 2 with a remainder of 256.
The next digit of our result is 2. 
Result so far: 62.0
Subtracting 972 from 1228 leaves us with 256.
Bring next digit (3) of the dividend behind the 256 and repeat the process: 2563 / 486

On to step 6:
The number 486 fits into 2563 5 times, leaving a remainder of 133.
Use 5 as the next digit of our solution. 
Result so far: 625.0
Subtract 2430 from 2563 to get 133.
Bring next digit (0) of the dividend behind the 133 and repeat the process: 1330 / 486

Advancing to step 7:
If we divide 1330 by 486, we get 2 and a remainder of 358.
The number 2 becomes the next digit in our result. 
Result so far: 6252.0
If we take 972 away from 1330, we end up with 358.
Include the next digit (4) from the dividend after 358, then repeat: 3584 / 486

Going ahead to step 8:
3584 divided by 486 is 7 with a remainder of 182.
Write down 7 as next digit of the result. 
Result so far: 62527.0
Deduct 3402 from 3584 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 9:
The number 486 fits into 1820 3 times, leaving a remainder of 362.
Use 3 as the next digit of our solution. 
Result so far: 62527.3
Subtract 1458 from 1820 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 10:
If we divide 3620 by 486, we get 7 and a remainder of 218.
The number 7 becomes the next digit in our result. 
Result so far: 62527.37
The remainder is 218 after subtracting 3402 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 11:
When dividing 2180 by 486, we get 4 with a remainder of 236.
The next digit of our result is 4. 
Result so far: 62527.374
If we subtract 1944 from 2180, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 12:
486 can be fit into 2360 4 times, resulting in a remainder of 416.
Write down 4 as next digit of the result. 
Result so far: 62527.3744
Deduct 1944 from 2360 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

In conclusion, the division gives 62527.3744 with a balance of 0.00416.
