42392407 divided by 581 
The aim is to understand the frequency of 581 in 42392407.

Let's proceed to step 1:
581 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 581

Moving on to step 2:
581 can be fit into 42 0 times, resulting in a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 581

Let's proceed to step 3:
If we divide 423 by 581, we get 0 and a remainder of 423.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 423 after subtracting 0 from 423.
Grab the next digit (9) from the dividend, add it to 423, then carry on: 4239 / 581

Going ahead to step 4:
When dividing 4239 by 581, we get 7 with a remainder of 172.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 4067 from 4239 and we're left with 172.
Append the next digit (2) from the dividend to 172 and continue with: 1722 / 581

Step 5:
The number 581 fits into 1722 2 times, leaving a remainder of 560.
Write down 2 as next digit of the result. 
Result so far: 72.0
The remainder is 560 after subtracting 1162 from 1722.
Take the next digit (4) from the dividend and append it to 560, then repeat: 5604 / 581

Step 6:
5604 divided by 581 is 9 with a remainder of 375.
Record the quotient 9 as the next digit in the result. 
Result so far: 729.0
The remainder is 375 after subtracting 5229 from 5604.
Append the next digit (0) from the dividend to 375 and continue with: 3750 / 581

Moving on to step 7:
581 goes into 3750 6 times with a remainder of 264.
Put 6 as the next digit of the answer. 
Result so far: 7296.0
Deduct 3486 from 3750 and we're left with 264.
Bring next digit (7) of the dividend behind the 264 and repeat the process: 2647 / 581

Moving on to step 8:
2647 divided by 581 is 4 with a remainder of 323.
Record the quotient 4 as the next digit in the result. 
Result so far: 72964.0
Deduct 2324 from 2647 and we're left with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Let's proceed to step 9:
3230 divided by 581 is 5 with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 72964.5
The remainder is 325 after subtracting 2905 from 3230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 10:
If we divide 3250 by 581, we get 5 and a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 72964.55
The remainder is 345 after subtracting 2905 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The quotient of the division is 72964.55, and the remainder is 0.345.
