68511572 ÷ 574 
The aim is to understand the frequency of 574 in 68511572.

On to step 1:
The number 574 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 574

Going ahead to step 2:
The number 574 fits into 68 0 times, leaving a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 574

Advancing to step 3:
685 divided by 574 is 1 with a remainder of 111.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 574 from 685 to get 111.
Append the next digit (1) from the dividend to 111 and continue with: 1111 / 574

On to step 4:
If we divide 1111 by 574, we get 1 and a remainder of 537.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 574 away from 1111, we end up with 537.
Take the next digit (1) from the dividend and append it to 537, then repeat: 5371 / 574

Let's proceed to step 5:
The number 574 fits into 5371 9 times, leaving a remainder of 205.
Put 9 as the next digit of the answer. 
Result so far: 119.0
If we take 5166 away from 5371, we end up with 205.
Fetch the next digit (5) from the dividend, attach it to 205 and continue: 2055 / 574

Step 6:
When dividing 2055 by 574, we get 3 with a remainder of 333.
The next digit of our result is 3. 
Result so far: 1193.0
If we take 1722 away from 2055, we end up with 333.
Include the next digit (7) from the dividend after 333, then repeat: 3337 / 574

Step 7:
574 goes into 3337 5 times with a remainder of 467.
Write down 5 as next digit of the result. 
Result so far: 11935.0
Subtracting 2870 from 3337 leaves us with 467.
Fetch the next digit (2) from the dividend, attach it to 467 and continue: 4672 / 574

Advancing to step 8:
574 goes into 4672 8 times with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 119358.0
Deduct 4592 from 4672 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
When dividing 800 by 574, we get 1 with a remainder of 226.
Record the quotient 1 as the next digit in the result. 
Result so far: 119358.1
If we subtract 574 from 800, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 10:
574 goes into 2260 3 times with a remainder of 538.
Put 3 as the next digit of the answer. 
Result so far: 119358.13
If we subtract 1722 from 2260, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 11:
The number 574 fits into 5380 9 times, leaving a remainder of 214.
Write down 9 as next digit of the result. 
Result so far: 119358.139
The remainder is 214 after subtracting 5166 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 12:
2140 divided by 574 is 3 with a remainder of 418.
The next digit of our result is 3. 
Result so far: 119358.1393
Deduct 1722 from 2140 and we're left with 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 13:
When dividing 4180 by 574, we get 7 with a remainder of 162.
Record the quotient 7 as the next digit in the result. 
Result so far: 119358.13937
Subtract 4018 from 4180 to 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.

Moving on to step 14:
574 goes into 1620 2 times with a remainder of 472.
The next digit of our result is 2. 
Result so far: 119358.139372
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.

Step 15:
If we divide 4720 by 574, we get 8 and a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 119358.1393728
If we subtract 4592 from 4720, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 16:
The number 574 fits into 1280 2 times, leaving a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 119358.13937282
Deduct 1148 from 1280 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Our division results in 119358.13937282 with a remaining 1.32e-07.
