71582173 divided by 980 
The aim is to understand the frequency of 980 in 71582173.

Advancing to step 1:
7 divided by 980 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 980

On to step 2:
980 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 980

Going ahead to step 3:
980 can be fit into 715 0 times, resulting in a remainder of 715.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 715, we get 715.
Fetch the next digit (8) from the dividend, attach it to 715 and continue: 7158 / 980

Moving on to step 4:
980 can be fit into 7158 7 times, resulting in a remainder of 298.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 6860 from 7158 leaves us with 298.
Bring next digit (2) of the dividend behind the 298 and repeat the process: 2982 / 980

Step 5:
The number 980 fits into 2982 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Subtract 2940 from 2982 to get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 980

On to step 6:
421 divided by 980 is 0 with a remainder of 421.
The next digit of our result is 0. 
Result so far: 730.0
If we subtract 0 from 421, we get 421.
Grab the next digit (7) from the dividend, add it to 421, then carry on: 4217 / 980

Step 7:
980 can be fit into 4217 4 times, resulting in a remainder of 297.
Record the quotient 4 as the next digit in the result. 
Result so far: 7304.0
Subtracting 3920 from 4217 leaves us with 297.
Bring next digit (3) of the dividend behind the 297 and repeat the process: 2973 / 980

On to step 8:
2973 divided by 980 is 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 73043.0
Subtracting 2940 from 2973 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
980 can be fit into 330 0 times, resulting in a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 73043.0
Subtracting 0 from 330 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
When dividing 3300 by 980, we get 3 with a remainder of 360.
Record the quotient 3 as the next digit in the result. 
Result so far: 73043.03
The remainder is 360 after subtracting 2940 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
980 can be fit into 3600 3 times, resulting in a remainder of 660.
Write down 3 as next digit of the result. 
Result so far: 73043.033
Subtract 2940 from 3600 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

In conclusion, the division gives 73043.033 with a balance of 0.066.
