85076639 ÷ 980 
The aim is to understand the frequency of 980 in 85076639.

Advancing to step 1:
The number 980 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 980

Advancing to step 2:
980 can be fit into 85 0 times, resulting in a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Fetch the next digit (0) from the dividend, attach it to 85 and continue: 850 / 980

Step 3:
980 can be fit into 850 0 times, resulting in a remainder of 850.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 850 to get 850.
Bring next digit (7) of the dividend behind the 850 and repeat the process: 8507 / 980

Advancing to step 4:
If we divide 8507 by 980, we get 8 and a remainder of 667.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7840 from 8507 leaves us with 667.
Include the next digit (6) from the dividend after 667, then repeat: 6676 / 980

Let's proceed to step 5:
6676 divided by 980 is 6 with a remainder of 796.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 5880 from 6676 leaves us with 796.
Include the next digit (6) from the dividend after 796, then repeat: 7966 / 980

Step 6:
980 goes into 7966 8 times with a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 868.0
If we subtract 7840 from 7966, we get 126.
Bring next digit (3) of the dividend behind the 126 and repeat the process: 1263 / 980

Advancing to step 7:
1263 divided by 980 is 1 with a remainder of 283.
Write down 1 as next digit of the result. 
Result so far: 8681.0
Deduct 980 from 1263 and we're left with 283.
Append the next digit (9) from the dividend to 283 and continue with: 2839 / 980

Moving on to step 8:
980 goes into 2839 2 times with a remainder of 879.
The next digit of our result is 2. 
Result so far: 86812.0
The remainder is 879 after subtracting 1960 from 2839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8790, and continue the process.

Going ahead to step 9:
8790 divided by 980 is 8 with a remainder of 950.
Write down 8 as next digit of the result. 
Result so far: 86812.8
If we subtract 7840 from 8790, we get 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Moving on to step 10:
The number 980 fits into 9500 9 times, leaving a remainder of 680.
The next digit of our result is 9. 
Result so far: 86812.89
If we take 8820 away from 9500, we end up 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.

Advancing to step 11:
980 can be fit into 6800 6 times, resulting in a remainder of 920.
Use 6 as the next digit of our solution. 
Result so far: 86812.896
Subtract 5880 from 6800 to 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.

Going ahead to step 12:
980 goes into 9200 9 times with a remainder of 380.
The next digit of our result is 9. 
Result so far: 86812.8969
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 13:
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: 86812.89693
Subtract 2940 from 3800 to 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.

Advancing to step 14:
When dividing 8600 by 980, we get 8 with a remainder of 760.
The next digit of our result is 8. 
Result so far: 86812.896938
Subtracting 7840 from 8600 leaves us 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.

On to step 15:
7600 divided by 980 is 7 with a remainder of 740.
Record the quotient 7 as the next digit in the result. 
Result so far: 86812.8969387
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 16:
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: 86812.89693877
The remainder is 540 after subtracting 6860 from 7400.
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 result is 86812.89693877 with a remainder of 5.4e-07.
