30980884 ÷ 418 
The aim is to understand the frequency of 418 in 30980884.

On to step 1:
The number 418 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 418

Advancing to step 2:
If we divide 30 by 418, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 418

On to step 3:
The number 418 fits into 309 0 times, leaving a remainder of 309.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 309, we end up with 309.
Fetch the next digit (8) from the dividend, attach it to 309 and continue: 3098 / 418

Let's proceed to step 4:
If we divide 3098 by 418, we get 7 and a remainder of 172.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 2926 from 3098, we get 172.
Append the next digit (0) from the dividend to 172 and continue with: 1720 / 418

Advancing to step 5:
If we divide 1720 by 418, we get 4 and a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we take 1672 away from 1720, we end up with 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 418

Let's proceed to step 6:
418 goes into 488 1 times with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 741.0
Subtracting 418 from 488 leaves us with 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 418

Advancing to step 7:
418 goes into 708 1 times with a remainder of 290.
Put 1 as the next digit of the answer. 
Result so far: 7411.0
Subtracting 418 from 708 leaves us with 290.
Fetch the next digit (4) from the dividend, attach it to 290 and continue: 2904 / 418

On to step 8:
The number 418 fits into 2904 6 times, leaving a remainder of 396.
The number 6 becomes the next digit in our result. 
Result so far: 74116.0
Subtract 2508 from 2904 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 9:
418 can be fit into 3960 9 times, resulting in a remainder of 198.
Put 9 as the next digit of the answer. 
Result so far: 74116.9
Subtracting 3762 from 3960 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 10:
When dividing 1980 by 418, we get 4 with a remainder of 308.
Record the quotient 4 as the next digit in the result. 
Result so far: 74116.94
Subtract 1672 from 1980 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 11:
418 can be fit into 3080 7 times, resulting in a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 74116.947
If we subtract 2926 from 3080, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 12:
When dividing 1540 by 418, we get 3 with a remainder of 286.
Write down 3 as next digit of the result. 
Result so far: 74116.9473
Subtracting 1254 from 1540 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 13:
If we divide 2860 by 418, we get 6 and a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 74116.94736
The remainder is 352 after subtracting 2508 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 14:
418 can be fit into 3520 8 times, resulting in a remainder of 176.
Use 8 as the next digit of our solution. 
Result so far: 74116.947368
Subtracting 3344 from 3520 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 15:
1760 divided by 418 is 4 with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 74116.9473684
If we subtract 1672 from 1760, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 16:
The number 418 fits into 880 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 74116.94736842
Subtract 836 from 880 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 74116.94736842 with a remainder of 4.4e-08.
