78491647 divided by 572 
The aim is to understand the frequency of 572 in 78491647.

Step 1:
If we divide 7 by 572, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 572

Let's proceed to step 2:
The number 572 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 572

Going ahead to step 3:
When dividing 784 by 572, we get 1 with a remainder of 212.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 572 away from 784, we end up with 212.
Include the next digit (9) from the dividend after 212, then repeat: 2129 / 572

Step 4:
If we divide 2129 by 572, we get 3 and a remainder of 413.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1716 from 2129 leaves us with 413.
Bring next digit (1) of the dividend behind the 413 and repeat the process: 4131 / 572

Going ahead to step 5:
If we divide 4131 by 572, we get 7 and a remainder of 127.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtract 4004 from 4131 to get 127.
Take the next digit (6) from the dividend and append it to 127, then repeat: 1276 / 572

Advancing to step 6:
572 goes into 1276 2 times with a remainder of 132.
Use 2 as the next digit of our solution. 
Result so far: 1372.0
Deduct 1144 from 1276 and we're left with 132.
Bring next digit (4) of the dividend behind the 132 and repeat the process: 1324 / 572

Moving on to step 7:
572 can be fit into 1324 2 times, resulting in a remainder of 180.
The next digit of our result is 2. 
Result so far: 13722.0
If we take 1144 away from 1324, we end up with 180.
Take the next digit (7) from the dividend and append it to 180, then repeat: 1807 / 572

Let's proceed to step 8:
572 can be fit into 1807 3 times, resulting in a remainder of 91.
The number 3 becomes the next digit in our result. 
Result so far: 137223.0
If we subtract 1716 from 1807, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 9:
572 can be fit into 910 1 times, resulting in a remainder of 338.
Put 1 as the next digit of the answer. 
Result so far: 137223.1
Subtract 572 from 910 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
3380 divided by 572 is 5 with a remainder of 520.
Use 5 as the next digit of our solution. 
Result so far: 137223.15
The remainder is 520 after subtracting 2860 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 11:
If we divide 5200 by 572, we get 9 and a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 137223.159
Deduct 5148 from 5200 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
572 goes into 520 0 times with a remainder of 520.
The next digit of our result is 0. 
Result so far: 137223.159
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 13:
572 can be fit into 5200 9 times, resulting in a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 137223.15909
If we take 5148 away from 5200, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
572 can be fit into 520 0 times, resulting in a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 137223.15909
Deduct 0 from 520 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 15:
When dividing 5200 by 572, we get 9 with a remainder of 52.
The next digit of our result is 9. 
Result so far: 137223.1590909
Deduct 5148 from 5200 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 16:
If we divide 520 by 572, we get 0 and a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 137223.1590909
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

After the division, we end up with 137223.1590909 and a remainder of 5.2e-07.
