71109213 ÷ 574 
The aim is to understand the frequency of 574 in 71109213.

Step 1:
574 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 574

Let's proceed to step 2:
71 divided by 574 is 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (1) from the dividend, add it to 71, then carry on: 711 / 574

Moving on to step 3:
The number 574 fits into 711 1 times, leaving a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 137 after subtracting 574 from 711.
Include the next digit (0) from the dividend after 137, then repeat: 1370 / 574

Advancing to step 4:
If we divide 1370 by 574, we get 2 and a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1148 away from 1370, we end up with 222.
Append the next digit (9) from the dividend to 222 and continue with: 2229 / 574

Let's proceed to step 5:
574 can be fit into 2229 3 times, resulting in a remainder of 507.
The next digit of our result is 3. 
Result so far: 123.0
If we take 1722 away from 2229, we end up with 507.
Grab the next digit (2) from the dividend, add it to 507, then carry on: 5072 / 574

Step 6:
5072 divided by 574 is 8 with a remainder of 480.
The next digit of our result is 8. 
Result so far: 1238.0
Subtract 4592 from 5072 to get 480.
Append the next digit (1) from the dividend to 480 and continue with: 4801 / 574

Let's proceed to step 7:
4801 divided by 574 is 8 with a remainder of 209.
Record the quotient 8 as the next digit in the result. 
Result so far: 12388.0
Subtract 4592 from 4801 to get 209.
Grab the next digit (3) from the dividend, add it to 209, then carry on: 2093 / 574

Step 8:
If we divide 2093 by 574, we get 3 and a remainder of 371.
Write down 3 as next digit of the result. 
Result so far: 123883.0
If we take 1722 away from 2093, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 9:
3710 divided by 574 is 6 with a remainder of 266.
Write down 6 as next digit of the result. 
Result so far: 123883.6
The remainder is 266 after subtracting 3444 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 10:
2660 divided by 574 is 4 with a remainder of 364.
Record the quotient 4 as the next digit in the result. 
Result so far: 123883.64
Subtracting 2296 from 2660 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 11:
574 goes into 3640 6 times with a remainder of 196.
The number 6 becomes the next digit in our result. 
Result so far: 123883.646
Deduct 3444 from 3640 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 12:
If we divide 1960 by 574, we get 3 and a remainder of 238.
Record the quotient 3 as the next digit in the result. 
Result so far: 123883.6463
Deduct 1722 from 1960 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 13:
If we divide 2380 by 574, we get 4 and a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 123883.64634
Subtract 2296 from 2380 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 14:
574 goes into 840 1 times with a remainder of 266.
Use 1 as the next digit of our solution. 
Result so far: 123883.646341
If we take 574 away from 840, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 15:
2660 divided by 574 is 4 with a remainder of 364.
Put 4 as the next digit of the answer. 
Result so far: 123883.6463414
The remainder is 364 after subtracting 2296 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 16:
574 can be fit into 3640 6 times, resulting in a remainder of 196.
Use 6 as the next digit of our solution. 
Result so far: 123883.64634146
Subtracting 3444 from 3640 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

After the division, we end up with 123883.64634146 and a remainder of 1.96e-07.
