97977630 ÷ 980 
The aim is to understand the frequency of 980 in 97977630.

Let's proceed to step 1:
The number 980 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 980

On to step 2:
97 divided by 980 is 0 with a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Include the next digit (9) from the dividend after 97, then repeat: 979 / 980

Step 3:
When dividing 979 by 980, we get 0 with a remainder of 979.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 979 leaves us with 979.
Append the next digit (7) from the dividend to 979 and continue with: 9797 / 980

Let's proceed to step 4:
The number 980 fits into 9797 9 times, leaving a remainder of 977.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 8820 from 9797, we get 977.
Grab the next digit (7) from the dividend, add it to 977, then carry on: 9777 / 980

Going ahead to step 5:
If we divide 9777 by 980, we get 9 and a remainder of 957.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 8820 from 9777 leaves us with 957.
Take the next digit (6) from the dividend and append it to 957, then repeat: 9576 / 980

Step 6:
980 goes into 9576 9 times with a remainder of 756.
The number 9 becomes the next digit in our result. 
Result so far: 999.0
The remainder is 756 after subtracting 8820 from 9576.
Grab the next digit (3) from the dividend, add it to 756, then carry on: 7563 / 980

Moving on to step 7:
980 can be fit into 7563 7 times, resulting in a remainder of 703.
The next digit of our result is 7. 
Result so far: 9997.0
The remainder is 703 after subtracting 6860 from 7563.
Take the next digit (0) from the dividend and append it to 703, then repeat: 7030 / 980

Step 8:
7030 divided by 980 is 7 with a remainder of 170.
The number 7 becomes the next digit in our result. 
Result so far: 99977.0
If we subtract 6860 from 7030, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 9:
980 can be fit into 1700 1 times, resulting in a remainder of 720.
Record the quotient 1 as the next digit in the result. 
Result so far: 99977.1
Subtracting 980 from 1700 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 10:
If we divide 7200 by 980, we get 7 and a remainder of 340.
Write down 7 as next digit of the result. 
Result so far: 99977.17
If we subtract 6860 from 7200, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 11:
980 goes into 3400 3 times with a remainder of 460.
Write down 3 as next digit of the result. 
Result so far: 99977.173
Subtracting 2940 from 3400 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 12:
980 can be fit into 4600 4 times, resulting in a remainder of 680.
Use 4 as the next digit of our solution. 
Result so far: 99977.1734
Subtracting 3920 from 4600 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 13:
980 goes into 6800 6 times with a remainder of 920.
Use 6 as the next digit of our solution. 
Result so far: 99977.17346
If we take 5880 away from 6800, we end up with 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Step 14:
980 can be fit into 9200 9 times, resulting in a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 99977.173469
The remainder is 380 after subtracting 8820 from 9200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 15:
3800 divided by 980 is 3 with a remainder of 860.
Record the quotient 3 as the next digit in the result. 
Result so far: 99977.1734693
Deduct 2940 from 3800 and we're left with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Moving on to step 16:
The number 980 fits into 8600 8 times, leaving a remainder of 760.
Write down 8 as next digit of the result. 
Result so far: 99977.17346938
If we take 7840 away from 8600, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The final outcome is 99977.17346938, with a leftover of 7.6e-07.
