80976913 ÷ 557 
The aim is to understand the frequency of 557 in 80976913.

Moving on to step 1:
557 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 557

Going ahead to step 2:
80 divided by 557 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 557

Going ahead to step 3:
When dividing 809 by 557, we get 1 with a remainder of 252.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 557 from 809 leaves us with 252.
Include the next digit (7) from the dividend after 252, then repeat: 2527 / 557

Moving on to step 4:
2527 divided by 557 is 4 with a remainder of 299.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 2228 away from 2527, we end up with 299.
Take the next digit (6) from the dividend and append it to 299, then repeat: 2996 / 557

Moving on to step 5:
The number 557 fits into 2996 5 times, leaving a remainder of 211.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Deduct 2785 from 2996 and we're left with 211.
Bring next digit (9) of the dividend behind the 211 and repeat the process: 2119 / 557

Advancing to step 6:
2119 divided by 557 is 3 with a remainder of 448.
Record the quotient 3 as the next digit in the result. 
Result so far: 1453.0
Deduct 1671 from 2119 and we're left with 448.
Append the next digit (1) from the dividend to 448 and continue with: 4481 / 557

Let's proceed to step 7:
The number 557 fits into 4481 8 times, leaving a remainder of 25.
The next digit of our result is 8. 
Result so far: 14538.0
The remainder is 25 after subtracting 4456 from 4481.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 557

Advancing to step 8:
253 divided by 557 is 0 with a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 145380.0
Deduct 0 from 253 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 9:
The number 557 fits into 2530 4 times, leaving a remainder of 302.
Put 4 as the next digit of the answer. 
Result so far: 145380.4
If we subtract 2228 from 2530, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 10:
557 goes into 3020 5 times with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 145380.45
If we take 2785 away from 3020, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 11:
When dividing 2350 by 557, we get 4 with a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 145380.454
Subtract 2228 from 2350 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 12:
557 goes into 1220 2 times with a remainder of 106.
Put 2 as the next digit of the answer. 
Result so far: 145380.4542
If we subtract 1114 from 1220, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 13:
If we divide 1060 by 557, we get 1 and a remainder of 503.
Use 1 as the next digit of our solution. 
Result so far: 145380.45421
If we take 557 away from 1060, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Advancing to step 14:
The number 557 fits into 5030 9 times, leaving a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 145380.454219
If we subtract 5013 from 5030, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 15:
The number 557 fits into 170 0 times, leaving a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 145380.454219
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 16:
The number 557 fits into 1700 3 times, leaving a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 145380.45421903
If we subtract 1671 from 1700, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 145380.45421903 with a balance of 2.9e-08.
