56642600 divided by 581 
The aim is to understand the frequency of 581 in 56642600.

On to step 1:
The number 581 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 581

Step 2:
56 divided by 581 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 581

Let's proceed to step 3:
When dividing 566 by 581, we get 0 with a remainder of 566.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 566 after subtracting 0 from 566.
Grab the next digit (4) from the dividend, add it to 566, then carry on: 5664 / 581

Moving on to step 4:
581 goes into 5664 9 times with a remainder of 435.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 435 after subtracting 5229 from 5664.
Fetch the next digit (2) from the dividend, attach it to 435 and continue: 4352 / 581

Advancing to step 5:
The number 581 fits into 4352 7 times, leaving a remainder of 285.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Subtracting 4067 from 4352 leaves us with 285.
Fetch the next digit (6) from the dividend, attach it to 285 and continue: 2856 / 581

Let's proceed to step 6:
The number 581 fits into 2856 4 times, leaving a remainder of 532.
Write down 4 as next digit of the result. 
Result so far: 974.0
If we take 2324 away from 2856, we end up with 532.
Include the next digit (0) from the dividend after 532, then repeat: 5320 / 581

Let's proceed to step 7:
581 can be fit into 5320 9 times, resulting in a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 9749.0
The remainder is 91 after subtracting 5229 from 5320.
Include the next digit (0) from the dividend after 91, then repeat: 910 / 581

Moving on to step 8:
When dividing 910 by 581, we get 1 with a remainder of 329.
The next digit of our result is 1. 
Result so far: 97491.0
Subtract 581 from 910 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Let's proceed to step 9:
3290 divided by 581 is 5 with a remainder of 385.
Put 5 as the next digit of the answer. 
Result so far: 97491.5
Subtracting 2905 from 3290 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 10:
3850 divided by 581 is 6 with a remainder of 364.
The next digit of our result is 6. 
Result so far: 97491.56
The remainder is 364 after subtracting 3486 from 3850.
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:
If we divide 3640 by 581, we get 6 and a remainder of 154.
Record the quotient 6 as the next digit in the result. 
Result so far: 97491.566
If we subtract 3486 from 3640, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final result is 97491.566 with a remainder of 0.0154.
