89901876 ÷ 305 
The aim is to understand the frequency of 305 in 89901876.

Moving on to step 1:
The number 305 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 305

Advancing to step 2:
The number 305 fits into 89 0 times, leaving a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Fetch the next digit (9) from the dividend, attach it to 89 and continue: 899 / 305

Moving on to step 3:
305 can be fit into 899 2 times, resulting in a remainder of 289.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 610 away from 899, we end up with 289.
Grab the next digit (0) from the dividend, add it to 289, then carry on: 2890 / 305

Advancing to step 4:
305 goes into 2890 9 times with a remainder of 145.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtract 2745 from 2890 to get 145.
Include the next digit (1) from the dividend after 145, then repeat: 1451 / 305

On to step 5:
305 goes into 1451 4 times with a remainder of 231.
Record the quotient 4 as the next digit in the result. 
Result so far: 294.0
If we subtract 1220 from 1451, we get 231.
Append the next digit (8) from the dividend to 231 and continue with: 2318 / 305

Moving on to step 6:
When dividing 2318 by 305, we get 7 with a remainder of 183.
The next digit of our result is 7. 
Result so far: 2947.0
Subtract 2135 from 2318 to get 183.
Append the next digit (7) from the dividend to 183 and continue with: 1837 / 305

Going ahead to step 7:
The number 305 fits into 1837 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 29476.0
Subtract 1830 from 1837 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 305

Moving on to step 8:
If we divide 76 by 305, we get 0 and a remainder of 76.
The next digit of our result is 0. 
Result so far: 294760.0
If we take 0 away from 76, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
If we divide 760 by 305, we get 2 and a remainder of 150.
The next digit of our result is 2. 
Result so far: 294760.2
Subtract 610 from 760 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
305 can be fit into 1500 4 times, resulting in a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 294760.24
The remainder is 280 after subtracting 1220 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 11:
305 can be fit into 2800 9 times, resulting in a remainder of 55.
The next digit of our result is 9. 
Result so far: 294760.249
Subtract 2745 from 2800 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 12:
305 goes into 550 1 times with a remainder of 245.
The next digit of our result is 1. 
Result so far: 294760.2491
Subtracting 305 from 550 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 13:
When dividing 2450 by 305, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 294760.24918
If we subtract 2440 from 2450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
305 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 294760.24918
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 15:
When dividing 1000 by 305, we get 3 with a remainder of 85.
Write down 3 as next digit of the result. 
Result so far: 294760.2491803
Deduct 915 from 1000 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 16:
305 can be fit into 850 2 times, resulting in a remainder of 240.
The next digit of our result is 2. 
Result so far: 294760.24918032
Deduct 610 from 850 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 294760.24918032 with a remainder of 2.4e-07.
