We're dividing 81068136 by 574 
The aim is to understand the frequency of 574 in 81068136.

Going ahead to step 1:
The number 574 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 574

Advancing to step 2:
If we divide 81 by 574, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 574

Advancing to step 3:
810 divided by 574 is 1 with a remainder of 236.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 574 away from 810, we end up with 236.
Take the next digit (6) from the dividend and append it to 236, then repeat: 2366 / 574

Step 4:
574 can be fit into 2366 4 times, resulting in a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 70 after subtracting 2296 from 2366.
Append the next digit (8) from the dividend to 70 and continue with: 708 / 574

Step 5:
708 divided by 574 is 1 with a remainder of 134.
Put 1 as the next digit of the answer. 
Result so far: 141.0
Subtracting 574 from 708 leaves us with 134.
Bring next digit (1) of the dividend behind the 134 and repeat the process: 1341 / 574

Advancing to step 6:
574 goes into 1341 2 times with a remainder of 193.
Write down 2 as next digit of the result. 
Result so far: 1412.0
Subtracting 1148 from 1341 leaves us with 193.
Fetch the next digit (3) from the dividend, attach it to 193 and continue: 1933 / 574

Advancing to step 7:
The number 574 fits into 1933 3 times, leaving a remainder of 211.
The next digit of our result is 3. 
Result so far: 14123.0
Subtract 1722 from 1933 to get 211.
Grab the next digit (6) from the dividend, add it to 211, then carry on: 2116 / 574

Let's proceed to step 8:
574 can be fit into 2116 3 times, resulting in a remainder of 394.
The number 3 becomes the next digit in our result. 
Result so far: 141233.0
If we take 1722 away from 2116, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 9:
574 can be fit into 3940 6 times, resulting in a remainder of 496.
Put 6 as the next digit of the answer. 
Result so far: 141233.6
If we take 3444 away from 3940, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 10:
574 goes into 4960 8 times with a remainder of 368.
Use 8 as the next digit of our solution. 
Result so far: 141233.68
If we subtract 4592 from 4960, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 11:
If we divide 3680 by 574, we get 6 and a remainder of 236.
Use 6 as the next digit of our solution. 
Result so far: 141233.686
Deduct 3444 from 3680 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 12:
574 goes into 2360 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 141233.6864
Deduct 2296 from 2360 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
The number 574 fits into 640 1 times, leaving a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 141233.68641
If we subtract 574 from 640, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
660 divided by 574 is 1 with a remainder of 86.
Record the quotient 1 as the next digit in the result. 
Result so far: 141233.686411
Subtract 574 from 660 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 141233.686411, with a leftover of 8.6e-06.
