81291261 ÷ 594 
The aim is to understand the frequency of 594 in 81291261.

Moving on to step 1:
594 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 594

Moving on to step 2:
The number 594 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 594

On to step 3:
The number 594 fits into 812 1 times, leaving a remainder of 218.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 594 away from 812, we end up with 218.
Append the next digit (9) from the dividend to 218 and continue with: 2189 / 594

On to step 4:
594 goes into 2189 3 times with a remainder of 407.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 407 after subtracting 1782 from 2189.
Append the next digit (1) from the dividend to 407 and continue with: 4071 / 594

On to step 5:
When dividing 4071 by 594, we get 6 with a remainder of 507.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
If we take 3564 away from 4071, we end up with 507.
Bring next digit (2) of the dividend behind the 507 and repeat the process: 5072 / 594

Going ahead to step 6:
When dividing 5072 by 594, we get 8 with a remainder of 320.
Write down 8 as next digit of the result. 
Result so far: 1368.0
Subtracting 4752 from 5072 leaves us with 320.
Take the next digit (6) from the dividend and append it to 320, then repeat: 3206 / 594

Let's proceed to step 7:
594 goes into 3206 5 times with a remainder of 236.
Use 5 as the next digit of our solution. 
Result so far: 13685.0
Subtracting 2970 from 3206 leaves us with 236.
Bring next digit (1) of the dividend behind the 236 and repeat the process: 2361 / 594

Moving on to step 8:
594 goes into 2361 3 times with a remainder of 579.
Write down 3 as next digit of the result. 
Result so far: 136853.0
Deduct 1782 from 2361 and we're left with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 9:
If we divide 5790 by 594, we get 9 and a remainder of 444.
Record the quotient 9 as the next digit in the result. 
Result so far: 136853.9
If we subtract 5346 from 5790, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 10:
594 can be fit into 4440 7 times, resulting in a remainder of 282.
Use 7 as the next digit of our solution. 
Result so far: 136853.97
Deduct 4158 from 4440 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 11:
If we divide 2820 by 594, we get 4 and a remainder of 444.
Record the quotient 4 as the next digit in the result. 
Result so far: 136853.974
Deduct 2376 from 2820 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 12:
594 can be fit into 4440 7 times, resulting in a remainder of 282.
Use 7 as the next digit of our solution. 
Result so far: 136853.9747
Subtract 4158 from 4440 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 13:
If we divide 2820 by 594, we get 4 and a remainder of 444.
Put 4 as the next digit of the answer. 
Result so far: 136853.97474
Subtract 2376 from 2820 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 14:
594 goes into 4440 7 times with a remainder of 282.
Put 7 as the next digit of the answer. 
Result so far: 136853.974747
If we take 4158 away from 4440, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 15:
If we divide 2820 by 594, we get 4 and a remainder of 444.
Record the quotient 4 as the next digit in the result. 
Result so far: 136853.9747474
Deduct 2376 from 2820 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 16:
4440 divided by 594 is 7 with a remainder of 282.
Use 7 as the next digit of our solution. 
Result so far: 136853.97474747
The remainder is 282 after subtracting 4158 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

The final result is 136853.97474747 with a remainder of 2.82e-07.
