We're dividing 80198897 by 570 
The aim is to understand the frequency of 570 in 80198897.

Going ahead to step 1:
570 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
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 / 570

Advancing to step 2:
The number 570 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 570

Advancing to step 3:
570 can be fit into 801 1 times, resulting in a remainder of 231.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 570 from 801 to get 231.
Append the next digit (9) from the dividend to 231 and continue with: 2319 / 570

Advancing to step 4:
570 goes into 2319 4 times with a remainder of 39.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 2280 from 2319 and we're left with 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 570

Moving on to step 5:
If we divide 398 by 570, we get 0 and a remainder of 398.
The next digit of our result is 0. 
Result so far: 140.0
If we take 0 away from 398, we end up with 398.
Fetch the next digit (8) from the dividend, attach it to 398 and continue: 3988 / 570

Going ahead to step 6:
570 goes into 3988 6 times with a remainder of 568.
Record the quotient 6 as the next digit in the result. 
Result so far: 1406.0
Subtracting 3420 from 3988 leaves us with 568.
Grab the next digit (9) from the dividend, add it to 568, then carry on: 5689 / 570

Going ahead to step 7:
The number 570 fits into 5689 9 times, leaving a remainder of 559.
The next digit of our result is 9. 
Result so far: 14069.0
Subtracting 5130 from 5689 leaves us with 559.
Grab the next digit (7) from the dividend, add it to 559, then carry on: 5597 / 570

Step 8:
If we divide 5597 by 570, we get 9 and a remainder of 467.
Use 9 as the next digit of our solution. 
Result so far: 140699.0
Deduct 5130 from 5597 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Advancing to step 9:
570 goes into 4670 8 times with a remainder of 110.
The next digit of our result is 8. 
Result so far: 140699.8
The remainder is 110 after subtracting 4560 from 4670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
570 can be fit into 1100 1 times, resulting in a remainder of 530.
Use 1 as the next digit of our solution. 
Result so far: 140699.81
If we take 570 away from 1100, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 11:
570 goes into 5300 9 times with a remainder of 170.
The next digit of our result is 9. 
Result so far: 140699.819
Subtract 5130 from 5300 to 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.

Let's proceed to step 12:
570 goes into 1700 2 times with a remainder of 560.
The next digit of our result is 2. 
Result so far: 140699.8192
If we subtract 1140 from 1700, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 13:
The number 570 fits into 5600 9 times, leaving a remainder of 470.
Write down 9 as next digit of the result. 
Result so far: 140699.81929
Subtract 5130 from 5600 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 14:
4700 divided by 570 is 8 with a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 140699.819298
If we take 4560 away from 4700, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 15:
1400 divided by 570 is 2 with a remainder of 260.
Use 2 as the next digit of our solution. 
Result so far: 140699.8192982
The remainder is 260 after subtracting 1140 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 16:
570 goes into 2600 4 times with a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 140699.81929824
Deduct 2280 from 2600 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 140699.81929824 and a remainder of 3.2e-07.
