We look at the division of 983859 by 46 
The aim is to understand the frequency of 46 in 983859.

Step 1:
46 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 46

Going ahead to step 2:
46 goes into 98 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 92 from 98 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 46

Going ahead to step 3:
When dividing 63 by 46, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 21.0
If we take 46 away from 63, we end up with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 46

On to step 4:
46 can be fit into 178 3 times, resulting in a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 213.0
Subtract 138 from 178 to get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 46

Let's proceed to step 5:
If we divide 405 by 46, we get 8 and a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 2138.0
If we subtract 368 from 405, we get 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 46

On to step 6:
When dividing 379 by 46, we get 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 21388.0
The remainder is 11 after subtracting 368 from 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
46 goes into 110 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 21388.2
If we take 92 away from 110, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
If we divide 180 by 46, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 21388.23
Subtract 138 from 180 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
When dividing 420 by 46, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 21388.239
Subtracting 414 from 420 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
46 can be fit into 60 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 21388.2391
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
When dividing 140 by 46, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 21388.23913
Subtract 138 from 140 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.

Advancing to step 12:
The number 46 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 21388.23913
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
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: 21388.2391304
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
The number 46 fits into 160 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 21388.23913043
If we take 138 away from 160, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 21388.23913043 with a remainder of 2.2e-08.
