81870966 ÷ 582 
The aim is to understand the frequency of 582 in 81870966.

Moving on to step 1:
582 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 582

Step 2:
If we divide 81 by 582, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 582

Moving on to step 3:
818 divided by 582 is 1 with a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 582 away from 818, we end up with 236.
Grab the next digit (7) from the dividend, add it to 236, then carry on: 2367 / 582

Going ahead to step 4:
When dividing 2367 by 582, we get 4 with a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 39 after subtracting 2328 from 2367.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 582

Advancing to step 5:
390 divided by 582 is 0 with a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
Subtracting 0 from 390 leaves us with 390.
Grab the next digit (9) from the dividend, add it to 390, then carry on: 3909 / 582

Going ahead to step 6:
The number 582 fits into 3909 6 times, leaving a remainder of 417.
Put 6 as the next digit of the answer. 
Result so far: 1406.0
Deduct 3492 from 3909 and we're left with 417.
Include the next digit (6) from the dividend after 417, then repeat: 4176 / 582

On to step 7:
582 goes into 4176 7 times with a remainder of 102.
The number 7 becomes the next digit in our result. 
Result so far: 14067.0
Subtract 4074 from 4176 to get 102.
Grab the next digit (6) from the dividend, add it to 102, then carry on: 1026 / 582

Moving on to step 8:
582 can be fit into 1026 1 times, resulting in a remainder of 444.
The next digit of our result is 1. 
Result so far: 140671.0
The remainder is 444 after subtracting 582 from 1026.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 9:
582 goes into 4440 7 times with a remainder of 366.
Write down 7 as next digit of the result. 
Result so far: 140671.7
Subtract 4074 from 4440 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 10:
If we divide 3660 by 582, we get 6 and a remainder of 168.
Put 6 as the next digit of the answer. 
Result so far: 140671.76
If we subtract 3492 from 3660, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 11:
The number 582 fits into 1680 2 times, leaving a remainder of 516.
Use 2 as the next digit of our solution. 
Result so far: 140671.762
Subtracting 1164 from 1680 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 12:
The number 582 fits into 5160 8 times, leaving a remainder of 504.
Record the quotient 8 as the next digit in the result. 
Result so far: 140671.7628
Subtract 4656 from 5160 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 13:
5040 divided by 582 is 8 with a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 140671.76288
If we take 4656 away from 5040, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final result is 140671.76288 with a remainder of 0.000384.
