18830404 ÷ 980 
The aim is to understand the frequency of 980 in 18830404.

Going ahead to step 1:
When dividing 1 by 980, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 980

Going ahead to step 2:
When dividing 18 by 980, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 980

Step 3:
188 divided by 980 is 0 with a remainder of 188.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 188 after subtracting 0 from 188.
Include the next digit (3) from the dividend after 188, then repeat: 1883 / 980

Going ahead to step 4:
If we divide 1883 by 980, we get 1 and a remainder of 903.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 980 from 1883, we get 903.
Bring next digit (0) of the dividend behind the 903 and repeat the process: 9030 / 980

Moving on to step 5:
When dividing 9030 by 980, we get 9 with a remainder of 210.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 8820 from 9030 leaves us with 210.
Take the next digit (4) from the dividend and append it to 210, then repeat: 2104 / 980

Going ahead to step 6:
980 can be fit into 2104 2 times, resulting in a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 192.0
Deduct 1960 from 2104 and we're left with 144.
Include the next digit (0) from the dividend after 144, then repeat: 1440 / 980

Step 7:
If we divide 1440 by 980, we get 1 and a remainder of 460.
The number 1 becomes the next digit in our result. 
Result so far: 1921.0
The remainder is 460 after subtracting 980 from 1440.
Grab the next digit (4) from the dividend, add it to 460, then carry on: 4604 / 980

On to step 8:
The number 980 fits into 4604 4 times, leaving a remainder of 684.
Write down 4 as next digit of the result. 
Result so far: 19214.0
If we take 3920 away from 4604, we end up with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 9:
980 goes into 6840 6 times with a remainder of 960.
Record the quotient 6 as the next digit in the result. 
Result so far: 19214.6
Subtract 5880 from 6840 to get 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

On to step 10:
9600 divided by 980 is 9 with a remainder of 780.
Write down 9 as next digit of the result. 
Result so far: 19214.69
Deduct 8820 from 9600 and we're left with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 11:
When dividing 7800 by 980, we get 7 with a remainder of 940.
Put 7 as the next digit of the answer. 
Result so far: 19214.697
The remainder is 940 after subtracting 6860 from 7800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Step 12:
980 goes into 9400 9 times with a remainder of 580.
The number 9 becomes the next digit in our result. 
Result so far: 19214.6979
Deduct 8820 from 9400 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 13:
980 can be fit into 5800 5 times, resulting in a remainder of 900.
Put 5 as the next digit of the answer. 
Result so far: 19214.69795
If we subtract 4900 from 5800, we get 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Advancing to step 14:
If we divide 9000 by 980, we get 9 and a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 19214.697959
Subtracting 8820 from 9000 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 15:
980 goes into 1800 1 times with a remainder of 820.
Put 1 as the next digit of the answer. 
Result so far: 19214.6979591
Deduct 980 from 1800 and we're left with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 16:
If we divide 8200 by 980, we get 8 and a remainder of 360.
Record the quotient 8 as the next digit in the result. 
Result so far: 19214.69795918
The remainder is 360 after subtracting 7840 from 8200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final outcome is 19214.69795918, with a leftover of 3.6e-07.
