43726075 ÷ 305 
The aim is to understand the frequency of 305 in 43726075.

Step 1:
305 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 305

Advancing to step 2:
If we divide 43 by 305, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 305

Advancing to step 3:
When dividing 437 by 305, we get 1 with a remainder of 132.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 305 from 437 and we're left with 132.
Grab the next digit (2) from the dividend, add it to 132, then carry on: 1322 / 305

On to step 4:
If we divide 1322 by 305, we get 4 and a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 102 after subtracting 1220 from 1322.
Grab the next digit (6) from the dividend, add it to 102, then carry on: 1026 / 305

Advancing to step 5:
When dividing 1026 by 305, we get 3 with a remainder of 111.
The next digit of our result is 3. 
Result so far: 143.0
The remainder is 111 after subtracting 915 from 1026.
Include the next digit (0) from the dividend after 111, then repeat: 1110 / 305

Going ahead to step 6:
1110 divided by 305 is 3 with a remainder of 195.
Record the quotient 3 as the next digit in the result. 
Result so far: 1433.0
If we take 915 away from 1110, we end up with 195.
Fetch the next digit (7) from the dividend, attach it to 195 and continue: 1957 / 305

Let's proceed to step 7:
1957 divided by 305 is 6 with a remainder of 127.
Write down 6 as next digit of the result. 
Result so far: 14336.0
Subtracting 1830 from 1957 leaves us with 127.
Grab the next digit (5) from the dividend, add it to 127, then carry on: 1275 / 305

On to step 8:
When dividing 1275 by 305, we get 4 with a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 143364.0
If we subtract 1220 from 1275, we 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.

Advancing to step 9:
305 goes into 550 1 times with a remainder of 245.
The next digit of our result is 1. 
Result so far: 143364.1
If we take 305 away from 550, we end up 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.

Going ahead to step 10:
If we divide 2450 by 305, we get 8 and a remainder of 10.
The next digit of our result is 8. 
Result so far: 143364.18
Subtract 2440 from 2450 to 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.

Let's proceed to step 11:
305 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 143364.18
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.

Advancing to step 12:
When dividing 1000 by 305, we get 3 with a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 143364.1803
Subtract 915 from 1000 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 13:
If we divide 850 by 305, we get 2 and a remainder of 240.
The next digit of our result is 2. 
Result so far: 143364.18032
If we take 610 away from 850, we end up 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.

Advancing to step 14:
305 can be fit into 2400 7 times, resulting in a remainder of 265.
Use 7 as the next digit of our solution. 
Result so far: 143364.180327
Deduct 2135 from 2400 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 15:
If we divide 2650 by 305, we get 8 and a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 143364.1803278
The remainder is 210 after subtracting 2440 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 16:
The number 305 fits into 2100 6 times, leaving a remainder of 270.
Put 6 as the next digit of the answer. 
Result so far: 143364.18032786
If we subtract 1830 from 2100, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

After the division, we end up with 143364.18032786 and a remainder of 2.7e-07.
