We look at the division of 391083 by 46 
The aim is to understand the frequency of 46 in 391083.

Step 1:
The number 46 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 46

Going ahead to step 2:
The number 46 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 46

Let's proceed to step 3:
The number 46 fits into 391 8 times, leaving a remainder of 23.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 368 from 391, we get 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 46

Advancing to step 4:
If we divide 230 by 46, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we take 230 away from 230, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 46

On to step 5:
If we divide 8 by 46, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 850.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 46

Step 6:
46 goes into 83 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 8501.0
Deduct 46 from 83 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
46 can be fit into 370 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8501.8
Subtract 368 from 370 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 46, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8501.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 46, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 8501.804
Deduct 184 from 200 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
When dividing 160 by 46, we get 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 8501.8043
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
46 goes into 220 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 8501.80434
Deduct 184 from 220 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
46 goes into 360 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 8501.804347
The remainder is 38 after subtracting 322 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
When dividing 380 by 46, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8501.8043478
Subtract 368 from 380 to get 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 14:
46 can be fit into 120 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 8501.80434782
Deduct 92 from 120 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 8501.80434782 with a remainder of 2.8e-08.
