86277004 ÷ 581 
The aim is to understand the frequency of 581 in 86277004.

Going ahead to step 1:
When dividing 8 by 581, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 581

On to step 2:
When dividing 86 by 581, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 581

Advancing to step 3:
581 can be fit into 862 1 times, resulting in a remainder of 281.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 581 from 862 to get 281.
Fetch the next digit (7) from the dividend, attach it to 281 and continue: 2817 / 581

On to step 4:
When dividing 2817 by 581, we get 4 with a remainder of 493.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 2324 from 2817, we get 493.
Take the next digit (7) from the dividend and append it to 493, then repeat: 4937 / 581

Advancing to step 5:
If we divide 4937 by 581, we get 8 and a remainder of 289.
Put 8 as the next digit of the answer. 
Result so far: 148.0
Subtracting 4648 from 4937 leaves us with 289.
Take the next digit (0) from the dividend and append it to 289, then repeat: 2890 / 581

Advancing to step 6:
2890 divided by 581 is 4 with a remainder of 566.
Write down 4 as next digit of the result. 
Result so far: 1484.0
Subtract 2324 from 2890 to get 566.
Bring next digit (0) of the dividend behind the 566 and repeat the process: 5660 / 581

Advancing to step 7:
When dividing 5660 by 581, we get 9 with a remainder of 431.
The next digit of our result is 9. 
Result so far: 14849.0
If we subtract 5229 from 5660, we get 431.
Append the next digit (4) from the dividend to 431 and continue with: 4314 / 581

Advancing to step 8:
When dividing 4314 by 581, we get 7 with a remainder of 247.
The next digit of our result is 7. 
Result so far: 148497.0
If we subtract 4067 from 4314, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 9:
When dividing 2470 by 581, we get 4 with a remainder of 146.
The next digit of our result is 4. 
Result so far: 148497.4
Deduct 2324 from 2470 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 10:
The number 581 fits into 1460 2 times, leaving a remainder of 298.
Record the quotient 2 as the next digit in the result. 
Result so far: 148497.42
If we take 1162 away from 1460, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 11:
The number 581 fits into 2980 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 148497.425
Subtract 2905 from 2980 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
581 goes into 750 1 times with a remainder of 169.
Write down 1 as next digit of the result. 
Result so far: 148497.4251
If we subtract 581 from 750, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 13:
When dividing 1690 by 581, we get 2 with a remainder of 528.
The number 2 becomes the next digit in our result. 
Result so far: 148497.42512
Deduct 1162 from 1690 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 14:
If we divide 5280 by 581, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 148497.425129
The remainder is 51 after subtracting 5229 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 15:
581 can be fit into 510 0 times, resulting in a remainder of 510.
Record the quotient 0 as the next digit in the result. 
Result so far: 148497.425129
The remainder is 510 after subtracting 0 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 16:
581 goes into 5100 8 times with a remainder of 452.
Put 8 as the next digit of the answer. 
Result so far: 148497.42512908
Subtract 4648 from 5100 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final outcome is 148497.42512908, with a leftover of 4.52e-07.
