We look at the division of 18162107 by 594 
The aim is to understand the frequency of 594 in 18162107.

Going ahead to step 1:
1 divided by 594 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 594

On to step 2:
If we divide 18 by 594, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 594

Advancing to step 3:
181 divided by 594 is 0 with a remainder of 181.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 181, we end up with 181.
Bring next digit (6) of the dividend behind the 181 and repeat the process: 1816 / 594

Going ahead to step 4:
When dividing 1816 by 594, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 34 after subtracting 1782 from 1816.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 594

On to step 5:
If we divide 342 by 594, we get 0 and a remainder of 342.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 342 and we're left with 342.
Bring next digit (1) of the dividend behind the 342 and repeat the process: 3421 / 594

Let's proceed to step 6:
3421 divided by 594 is 5 with a remainder of 451.
Record the quotient 5 as the next digit in the result. 
Result so far: 305.0
The remainder is 451 after subtracting 2970 from 3421.
Take the next digit (0) from the dividend and append it to 451, then repeat: 4510 / 594

Advancing to step 7:
If we divide 4510 by 594, we get 7 and a remainder of 352.
Record the quotient 7 as the next digit in the result. 
Result so far: 3057.0
Subtract 4158 from 4510 to get 352.
Bring next digit (7) of the dividend behind the 352 and repeat the process: 3527 / 594

Step 8:
The number 594 fits into 3527 5 times, leaving a remainder of 557.
Record the quotient 5 as the next digit in the result. 
Result so far: 30575.0
Subtracting 2970 from 3527 leaves us with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Advancing to step 9:
The number 594 fits into 5570 9 times, leaving a remainder of 224.
Write down 9 as next digit of the result. 
Result so far: 30575.9
Deduct 5346 from 5570 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 10:
The number 594 fits into 2240 3 times, leaving a remainder of 458.
Put 3 as the next digit of the answer. 
Result so far: 30575.93
If we subtract 1782 from 2240, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Going ahead to step 11:
If we divide 4580 by 594, we get 7 and a remainder of 422.
The next digit of our result is 7. 
Result so far: 30575.937
Subtracting 4158 from 4580 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 12:
The number 594 fits into 4220 7 times, leaving a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 30575.9377
If we take 4158 away from 4220, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 30575.9377, with a leftover of 0.00062.
