80997498 divided by 574 
The aim is to understand the frequency of 574 in 80997498.

Moving on to step 1:
574 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
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 574

Advancing to step 2:
574 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 574

Step 3:
574 goes into 809 1 times with a remainder of 235.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 574 from 809, we get 235.
Fetch the next digit (9) from the dividend, attach it to 235 and continue: 2359 / 574

Step 4:
The number 574 fits into 2359 4 times, leaving a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 2296 from 2359 leaves us with 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 574

Let's proceed to step 5:
637 divided by 574 is 1 with a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 141.0
If we subtract 574 from 637, we get 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 574

On to step 6:
634 divided by 574 is 1 with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 1411.0
If we subtract 574 from 634, we get 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 574

Advancing to step 7:
When dividing 609 by 574, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 14111.0
Subtracting 574 from 609 leaves us with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 574

Going ahead to step 8:
The number 574 fits into 358 0 times, leaving a remainder of 358.
Write down 0 as next digit of the result. 
Result so far: 141110.0
If we subtract 0 from 358, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 9:
The number 574 fits into 3580 6 times, leaving a remainder of 136.
Use 6 as the next digit of our solution. 
Result so far: 141110.6
Subtract 3444 from 3580 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 10:
The number 574 fits into 1360 2 times, leaving a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 141110.62
If we take 1148 away from 1360, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 11:
574 goes into 2120 3 times with a remainder of 398.
Record the quotient 3 as the next digit in the result. 
Result so far: 141110.623
Deduct 1722 from 2120 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 12:
The number 574 fits into 3980 6 times, leaving a remainder of 536.
Put 6 as the next digit of the answer. 
Result so far: 141110.6236
Subtract 3444 from 3980 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 13:
When dividing 5360 by 574, we get 9 with a remainder of 194.
The number 9 becomes the next digit in our result. 
Result so far: 141110.62369
Subtracting 5166 from 5360 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 14:
574 can be fit into 1940 3 times, resulting in a remainder of 218.
Write down 3 as next digit of the result. 
Result so far: 141110.623693
Subtracting 1722 from 1940 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 15:
The number 574 fits into 2180 3 times, leaving a remainder of 458.
Use 3 as the next digit of our solution. 
Result so far: 141110.6236933
Deduct 1722 from 2180 and we're left with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

The quotient of the division is 141110.6236933, and the remainder is 4.58e-06.
