76183490 ÷ 305 
The aim is to understand the frequency of 305 in 76183490.

Let's proceed to step 1:
7 divided by 305 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 305

On to step 2:
When dividing 76 by 305, we get 0 with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Append the next digit (1) from the dividend to 76 and continue with: 761 / 305

Advancing to step 3:
305 goes into 761 2 times with a remainder of 151.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 610 from 761 to get 151.
Include the next digit (8) from the dividend after 151, then repeat: 1518 / 305

Advancing to step 4:
When dividing 1518 by 305, we get 4 with a remainder of 298.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 298 after subtracting 1220 from 1518.
Include the next digit (3) from the dividend after 298, then repeat: 2983 / 305

Going ahead to step 5:
If we divide 2983 by 305, we get 9 and a remainder of 238.
Record the quotient 9 as the next digit in the result. 
Result so far: 249.0
Subtract 2745 from 2983 to get 238.
Take the next digit (4) from the dividend and append it to 238, then repeat: 2384 / 305

Let's proceed to step 6:
The number 305 fits into 2384 7 times, leaving a remainder of 249.
Use 7 as the next digit of our solution. 
Result so far: 2497.0
Subtracting 2135 from 2384 leaves us with 249.
Fetch the next digit (9) from the dividend, attach it to 249 and continue: 2499 / 305

Moving on to step 7:
2499 divided by 305 is 8 with a remainder of 59.
The next digit of our result is 8. 
Result so far: 24978.0
Deduct 2440 from 2499 and we're left with 59.
Include the next digit (0) from the dividend after 59, then repeat: 590 / 305

Advancing to step 8:
If we divide 590 by 305, we get 1 and a remainder of 285.
The number 1 becomes the next digit in our result. 
Result so far: 249781.0
Deduct 305 from 590 and we're left 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.

Advancing to step 9:
305 goes into 2850 9 times with a remainder of 105.
Write down 9 as next digit of the result. 
Result so far: 249781.9
Subtracting 2745 from 2850 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 10:
When dividing 1050 by 305, we get 3 with a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 249781.93
Subtracting 915 from 1050 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 11:
305 goes into 1350 4 times with a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 249781.934
Deduct 1220 from 1350 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 12:
1300 divided by 305 is 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 249781.9344
If we subtract 1220 from 1300, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 249781.9344, with a leftover of 0.0008.
