30781324 ÷ 980 
The aim is to understand the frequency of 980 in 30781324.

Going ahead to step 1:
The number 980 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 980

Let's proceed to step 2:
If we divide 30 by 980, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 980

Step 3:
If we divide 307 by 980, we get 0 and a remainder of 307.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 307 to get 307.
Bring next digit (8) of the dividend behind the 307 and repeat the process: 3078 / 980

On to step 4:
980 goes into 3078 3 times with a remainder of 138.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 2940 from 3078, we get 138.
Bring next digit (1) of the dividend behind the 138 and repeat the process: 1381 / 980

On to step 5:
When dividing 1381 by 980, we get 1 with a remainder of 401.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 980 from 1381 and we're left with 401.
Fetch the next digit (3) from the dividend, attach it to 401 and continue: 4013 / 980

Going ahead to step 6:
When dividing 4013 by 980, we get 4 with a remainder of 93.
Use 4 as the next digit of our solution. 
Result so far: 314.0
The remainder is 93 after subtracting 3920 from 4013.
Append the next digit (2) from the dividend to 93 and continue with: 932 / 980

Step 7:
980 goes into 932 0 times with a remainder of 932.
Put 0 as the next digit of the answer. 
Result so far: 3140.0
If we take 0 away from 932, we end up with 932.
Include the next digit (4) from the dividend after 932, then repeat: 9324 / 980

Step 8:
980 can be fit into 9324 9 times, resulting in a remainder of 504.
Put 9 as the next digit of the answer. 
Result so far: 31409.0
Subtract 8820 from 9324 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 9:
The number 980 fits into 5040 5 times, leaving a remainder of 140.
The next digit of our result is 5. 
Result so far: 31409.5
If we subtract 4900 from 5040, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
If we divide 1400 by 980, we get 1 and a remainder of 420.
Put 1 as the next digit of the answer. 
Result so far: 31409.51
The remainder is 420 after subtracting 980 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 11:
If we divide 4200 by 980, we get 4 and a remainder of 280.
Write down 4 as next digit of the result. 
Result so far: 31409.514
Subtracting 3920 from 4200 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
2800 divided by 980 is 2 with a remainder of 840.
Write down 2 as next digit of the result. 
Result so far: 31409.5142
Subtracting 1960 from 2800 leaves us with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Moving on to step 13:
8400 divided by 980 is 8 with a remainder of 560.
The next digit of our result is 8. 
Result so far: 31409.51428
If we take 7840 away from 8400, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 14:
If we divide 5600 by 980, we get 5 and a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 31409.514285
Deduct 4900 from 5600 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 15:
980 can be fit into 7000 7 times, resulting in a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 31409.5142857
If we subtract 6860 from 7000, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 16:
1400 divided by 980 is 1 with a remainder of 420.
The next digit of our result is 1. 
Result so far: 31409.51428571
If we take 980 away from 1400, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The final result is 31409.51428571 with a remainder of 4.2e-07.
