731091 ÷ 46 
The aim is to understand the frequency of 46 in 731091.

Step 1:
7 divided by 46 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 46

Moving on to step 2:
46 goes into 73 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 46 from 73 leaves us with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 46

Moving on to step 3:
271 divided by 46 is 5 with a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 230 from 271, we get 41.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 46

Let's proceed to step 4:
46 goes into 410 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
If we subtract 368 from 410, we get 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 46

On to step 5:
46 goes into 429 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 1589.0
Subtracting 414 from 429 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 46

Moving on to step 6:
The number 46 fits into 151 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 15893.0
Subtracting 138 from 151 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
46 can be fit into 130 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 15893.2
Subtract 92 from 130 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
When dividing 380 by 46, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 15893.28
If we take 368 away from 380, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
46 can be fit into 120 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 15893.282
The remainder is 28 after subtracting 92 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
When dividing 280 by 46, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 15893.2826
If we subtract 276 from 280, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
46 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 15893.2826
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
The number 46 fits into 400 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 15893.282608
Deduct 368 from 400 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
320 divided by 46 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 15893.2826086
Deduct 276 from 320 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
The number 46 fits into 440 9 times, leaving a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 15893.28260869
If we subtract 414 from 440, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 15893.28260869 with a remainder of 2.6e-08.
