We look at the division of 79215566 by 566 
The aim is to understand the frequency of 566 in 79215566.

Step 1:
566 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 566

Step 2:
79 divided by 566 is 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Append the next digit (2) from the dividend to 79 and continue with: 792 / 566

Step 3:
566 can be fit into 792 1 times, resulting in a remainder of 226.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 566 from 792 and we're left with 226.
Fetch the next digit (1) from the dividend, attach it to 226 and continue: 2261 / 566

On to step 4:
If we divide 2261 by 566, we get 3 and a remainder of 563.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1698 from 2261 and we're left with 563.
Bring next digit (5) of the dividend behind the 563 and repeat the process: 5635 / 566

Advancing to step 5:
When dividing 5635 by 566, we get 9 with a remainder of 541.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
Subtract 5094 from 5635 to get 541.
Fetch the next digit (5) from the dividend, attach it to 541 and continue: 5415 / 566

Let's proceed to step 6:
If we divide 5415 by 566, we get 9 and a remainder of 321.
Record the quotient 9 as the next digit in the result. 
Result so far: 1399.0
If we take 5094 away from 5415, we end up with 321.
Take the next digit (6) from the dividend and append it to 321, then repeat: 3216 / 566

Going ahead to step 7:
If we divide 3216 by 566, we get 5 and a remainder of 386.
Use 5 as the next digit of our solution. 
Result so far: 13995.0
If we take 2830 away from 3216, we end up with 386.
Take the next digit (6) from the dividend and append it to 386, then repeat: 3866 / 566

On to step 8:
When dividing 3866 by 566, we get 6 with a remainder of 470.
Put 6 as the next digit of the answer. 
Result so far: 139956.0
Subtract 3396 from 3866 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 9:
When dividing 4700 by 566, we get 8 with a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 139956.8
Subtracting 4528 from 4700 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 10:
If we divide 1720 by 566, we get 3 and a remainder of 22.
The next digit of our result is 3. 
Result so far: 139956.83
The remainder is 22 after subtracting 1698 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
566 goes into 220 0 times with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 139956.83
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 12:
The number 566 fits into 2200 3 times, leaving a remainder of 502.
Record the quotient 3 as the next digit in the result. 
Result so far: 139956.8303
Subtracting 1698 from 2200 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 13:
If we divide 5020 by 566, we get 8 and a remainder of 492.
Record the quotient 8 as the next digit in the result. 
Result so far: 139956.83038
Subtracting 4528 from 5020 leaves us with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Moving on to step 14:
566 goes into 4920 8 times with a remainder of 392.
The next digit of our result is 8. 
Result so far: 139956.830388
If we take 4528 away from 4920, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

In conclusion, the division gives 139956.830388 with a balance of 3.92e-05.
