30306666 ÷ 980 
We want to figure out the number of times 30306666 can be divided by 980.

Let's proceed to step 1:
The number 980 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 980

Step 2:
30 divided by 980 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 980

Advancing to step 3:
303 divided by 980 is 0 with a remainder of 303.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 303, we get 303.
Bring next digit (0) of the dividend behind the 303 and repeat the process: 3030 / 980

Going ahead to step 4:
The number 980 fits into 3030 3 times, leaving a remainder of 90.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 90 after subtracting 2940 from 3030.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 980

On to step 5:
980 can be fit into 906 0 times, resulting in a remainder of 906.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 906 to get 906.
Grab the next digit (6) from the dividend, add it to 906, then carry on: 9066 / 980

Going ahead to step 6:
9066 divided by 980 is 9 with a remainder of 246.
Record the quotient 9 as the next digit in the result. 
Result so far: 309.0
Subtract 8820 from 9066 to get 246.
Fetch the next digit (6) from the dividend, attach it to 246 and continue: 2466 / 980

On to step 7:
980 can be fit into 2466 2 times, resulting in a remainder of 506.
The next digit of our result is 2. 
Result so far: 3092.0
Subtracting 1960 from 2466 leaves us with 506.
Bring next digit (6) of the dividend behind the 506 and repeat the process: 5066 / 980

Going ahead to step 8:
If we divide 5066 by 980, we get 5 and a remainder of 166.
Record the quotient 5 as the next digit in the result. 
Result so far: 30925.0
The remainder is 166 after subtracting 4900 from 5066.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 9:
980 can be fit into 1660 1 times, resulting in a remainder of 680.
Write down 1 as next digit of the result. 
Result so far: 30925.1
If we subtract 980 from 1660, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 10:
6800 divided by 980 is 6 with a remainder of 920.
The number 6 becomes the next digit in our result. 
Result so far: 30925.16
If we subtract 5880 from 6800, we get 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Let's proceed to step 11:
9200 divided by 980 is 9 with a remainder of 380.
Use 9 as the next digit of our solution. 
Result so far: 30925.169
If we subtract 8820 from 9200, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 12:
3800 divided by 980 is 3 with a remainder of 860.
The number 3 becomes the next digit in our result. 
Result so far: 30925.1693
If we subtract 2940 from 3800, we get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

On to step 13:
980 goes into 8600 8 times with a remainder of 760.
The next digit of our result is 8. 
Result so far: 30925.16938
If we subtract 7840 from 8600, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 14:
If we divide 7600 by 980, we get 7 and a remainder of 740.
Use 7 as the next digit of our solution. 
Result so far: 30925.169387
Subtract 6860 from 7600 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Going ahead to step 15:
The number 980 fits into 7400 7 times, leaving a remainder of 540.
Use 7 as the next digit of our solution. 
Result so far: 30925.1693877
Subtract 6860 from 7400 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final outcome is 30925.1693877, with a leftover of 5.4e-06.
