Let's divide 81770736 by 574
The aim is to understand the frequency of 574 in 81770736.

Moving on to step 1:
The number 574 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 574

Moving on to step 2:
574 can be fit into 81 0 times, resulting in a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 574

Moving on to step 3:
574 can be fit into 817 1 times, resulting in a remainder of 243.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 574 from 817, we get 243.
Append the next digit (7) from the dividend to 243 and continue with: 2437 / 574

Going ahead to step 4:
574 can be fit into 2437 4 times, resulting in a remainder of 141.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2296 from 2437, we get 141.
Bring next digit (0) of the dividend behind the 141 and repeat the process: 1410 / 574

Let's proceed to step 5:
If we divide 1410 by 574, we get 2 and a remainder of 262.
The next digit of our result is 2. 
Result so far: 142.0
If we subtract 1148 from 1410, we get 262.
Include the next digit (7) from the dividend after 262, then repeat: 2627 / 574

On to step 6:
574 goes into 2627 4 times with a remainder of 331.
Put 4 as the next digit of the answer. 
Result so far: 1424.0
If we take 2296 away from 2627, we end up with 331.
Grab the next digit (3) from the dividend, add it to 331, then carry on: 3313 / 574

Let's proceed to step 7:
When dividing 3313 by 574, we get 5 with a remainder of 443.
Use 5 as the next digit of our solution. 
Result so far: 14245.0
The remainder is 443 after subtracting 2870 from 3313.
Append the next digit (6) from the dividend to 443 and continue with: 4436 / 574

Advancing to step 8:
If we divide 4436 by 574, we get 7 and a remainder of 418.
Put 7 as the next digit of the answer. 
Result so far: 142457.0
If we subtract 4018 from 4436, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 9:
574 goes into 4180 7 times with a remainder of 162.
The number 7 becomes the next digit in our result. 
Result so far: 142457.7
If we subtract 4018 from 4180, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 10:
The number 574 fits into 1620 2 times, leaving a remainder of 472.
Record the quotient 2 as the next digit in the result. 
Result so far: 142457.72
If we take 1148 away from 1620, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 11:
4720 divided by 574 is 8 with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 142457.728
If we take 4592 away from 4720, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
574 can be fit into 1280 2 times, resulting in a remainder of 132.
The number 2 becomes the next digit in our result. 
Result so far: 142457.7282
If we subtract 1148 from 1280, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
If we divide 1320 by 574, we get 2 and a remainder of 172.
The number 2 becomes the next digit in our result. 
Result so far: 142457.72822
Subtract 1148 from 1320 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final result is 142457.72822 with a remainder of 0.000172.
