49830666 ÷ 478 
The aim is to understand the frequency of 478 in 49830666.

Going ahead to step 1:
4 divided by 478 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 478

Going ahead to step 2:
478 goes into 49 0 times with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 478

Going ahead to step 3:
The number 478 fits into 498 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 478 from 498 to get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 478

Step 4:
If we divide 203 by 478, we get 0 and a remainder of 203.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 203 leaves us with 203.
Append the next digit (0) from the dividend to 203 and continue with: 2030 / 478

On to step 5:
When dividing 2030 by 478, we get 4 with a remainder of 118.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtract 1912 from 2030 to get 118.
Bring next digit (6) of the dividend behind the 118 and repeat the process: 1186 / 478

Advancing to step 6:
478 can be fit into 1186 2 times, resulting in a remainder of 230.
The next digit of our result is 2. 
Result so far: 1042.0
Subtract 956 from 1186 to get 230.
Fetch the next digit (6) from the dividend, attach it to 230 and continue: 2306 / 478

Step 7:
When dividing 2306 by 478, we get 4 with a remainder of 394.
Use 4 as the next digit of our solution. 
Result so far: 10424.0
If we take 1912 away from 2306, we end up with 394.
Fetch the next digit (6) from the dividend, attach it to 394 and continue: 3946 / 478

Let's proceed to step 8:
If we divide 3946 by 478, we get 8 and a remainder of 122.
The next digit of our result is 8. 
Result so far: 104248.0
If we take 3824 away from 3946, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 9:
If we divide 1220 by 478, we get 2 and a remainder of 264.
The next digit of our result is 2. 
Result so far: 104248.2
The remainder is 264 after subtracting 956 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 10:
478 can be fit into 2640 5 times, resulting in a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 104248.25
Subtracting 2390 from 2640 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 11:
If we divide 2500 by 478, we get 5 and a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 104248.255
If we take 2390 away from 2500, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 104248.255, with a leftover of 0.011.
