48567818 ÷ 581 
The aim is to understand the frequency of 581 in 48567818.

On to step 1:
581 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 581

On to step 2:
48 divided by 581 is 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Grab the next digit (5) from the dividend, add it to 48, then carry on: 485 / 581

Going ahead to step 3:
If we divide 485 by 581, we get 0 and a remainder of 485.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 485, we end up with 485.
Grab the next digit (6) from the dividend, add it to 485, then carry on: 4856 / 581

Advancing to step 4:
581 can be fit into 4856 8 times, resulting in a remainder of 208.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 208 after subtracting 4648 from 4856.
Append the next digit (7) from the dividend to 208 and continue with: 2087 / 581

Let's proceed to step 5:
581 goes into 2087 3 times with a remainder of 344.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Deduct 1743 from 2087 and we're left with 344.
Fetch the next digit (8) from the dividend, attach it to 344 and continue: 3448 / 581

Let's proceed to step 6:
581 can be fit into 3448 5 times, resulting in a remainder of 543.
Use 5 as the next digit of our solution. 
Result so far: 835.0
The remainder is 543 after subtracting 2905 from 3448.
Fetch the next digit (1) from the dividend, attach it to 543 and continue: 5431 / 581

On to step 7:
If we divide 5431 by 581, we get 9 and a remainder of 202.
The next digit of our result is 9. 
Result so far: 8359.0
Subtract 5229 from 5431 to get 202.
Grab the next digit (8) from the dividend, add it to 202, then carry on: 2028 / 581

Step 8:
581 goes into 2028 3 times with a remainder of 285.
Write down 3 as next digit of the result. 
Result so far: 83593.0
Subtracting 1743 from 2028 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 9:
2850 divided by 581 is 4 with a remainder of 526.
The number 4 becomes the next digit in our result. 
Result so far: 83593.4
If we take 2324 away from 2850, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Let's proceed to step 10:
5260 divided by 581 is 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 83593.49
Subtract 5229 from 5260 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
581 goes into 310 0 times with a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 83593.49
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 12:
When dividing 3100 by 581, we get 5 with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 83593.4905
The remainder is 195 after subtracting 2905 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 13:
581 can be fit into 1950 3 times, resulting in a remainder of 207.
The number 3 becomes the next digit in our result. 
Result so far: 83593.49053
Deduct 1743 from 1950 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 14:
2070 divided by 581 is 3 with a remainder of 327.
The next digit of our result is 3. 
Result so far: 83593.490533
The remainder is 327 after subtracting 1743 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

In conclusion, the division gives 83593.490533 with a balance of 3.27e-05.
