We look at the division of 139641 by 46 
The aim is to understand the frequency of 46 in 139641.

Moving on to step 1:
46 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 46

Step 2:
13 divided by 46 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 46

Step 3:
139 divided by 46 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 1 after subtracting 138 from 139.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 46

Moving on to step 4:
If we divide 16 by 46, we get 0 and a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 46

Advancing to step 5:
If we divide 164 by 46, we get 3 and a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 303.0
If we take 138 away from 164, we end up with 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 46

Going ahead to step 6:
261 divided by 46 is 5 with a remainder of 31.
The next digit of our result is 5. 
Result so far: 3035.0
If we subtract 230 from 261, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
310 divided by 46 is 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 3035.6
If we subtract 276 from 310, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
46 can be fit into 340 7 times, resulting in a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 3035.67
Subtract 322 from 340 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
46 can be fit into 180 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 3035.673
The remainder is 42 after subtracting 138 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
When dividing 420 by 46, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 3035.6739
The remainder is 6 after subtracting 414 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
60 divided by 46 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 3035.67391
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
46 goes into 140 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3035.673913
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
When dividing 20 by 46, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3035.673913
The remainder is 20 after subtracting 0 from 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 14:
46 goes into 200 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 3035.67391304
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.

The final result is 3035.67391304 with a remainder of 1.6e-08.
