We look at the division of 1557813 by 566 
The aim is to understand the frequency of 566 in 1557813.

Moving on to step 1:
1 divided by 566 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 566

Step 2:
566 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 566

Moving on to step 3:
155 divided by 566 is 0 with a remainder of 155.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 155 to get 155.
Take the next digit (7) from the dividend and append it to 155, then repeat: 1557 / 566

Going ahead to step 4:
The number 566 fits into 1557 2 times, leaving a remainder of 425.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1132 away from 1557, we end up with 425.
Grab the next digit (8) from the dividend, add it to 425, then carry on: 4258 / 566

Advancing to step 5:
566 goes into 4258 7 times with a remainder of 296.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtract 3962 from 4258 to get 296.
Grab the next digit (1) from the dividend, add it to 296, then carry on: 2961 / 566

Step 6:
When dividing 2961 by 566, we get 5 with a remainder of 131.
Record the quotient 5 as the next digit in the result. 
Result so far: 275.0
The remainder is 131 after subtracting 2830 from 2961.
Include the next digit (3) from the dividend after 131, then repeat: 1313 / 566

Moving on to step 7:
When dividing 1313 by 566, we get 2 with a remainder of 181.
The next digit of our result is 2. 
Result so far: 2752.0
Subtract 1132 from 1313 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 8:
The number 566 fits into 1810 3 times, leaving a remainder of 112.
Use 3 as the next digit of our solution. 
Result so far: 2752.3
Subtract 1698 from 1810 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 9:
1120 divided by 566 is 1 with a remainder of 554.
Put 1 as the next digit of the answer. 
Result so far: 2752.31
Subtract 566 from 1120 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 10:
566 goes into 5540 9 times with a remainder of 446.
Write down 9 as next digit of the result. 
Result so far: 2752.319
If we subtract 5094 from 5540, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 11:
If we divide 4460 by 566, we get 7 and a remainder of 498.
Use 7 as the next digit of our solution. 
Result so far: 2752.3197
The remainder is 498 after subtracting 3962 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Moving on to step 12:
566 can be fit into 4980 8 times, resulting in a remainder of 452.
Record the quotient 8 as the next digit in the result. 
Result so far: 2752.31978
If we take 4528 away from 4980, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 13:
4520 divided by 566 is 7 with a remainder of 558.
Use 7 as the next digit of our solution. 
Result so far: 2752.319787
If we subtract 3962 from 4520, we get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Advancing to step 14:
566 goes into 5580 9 times with a remainder of 486.
Record the quotient 9 as the next digit in the result. 
Result so far: 2752.3197879
Subtracting 5094 from 5580 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 15:
The number 566 fits into 4860 8 times, leaving a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 2752.31978798
Subtracting 4528 from 4860 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

In conclusion, the division gives 2752.31978798 with a balance of 3.32e-07.
