We look at the division of 138898 by 46 
The aim is to understand the frequency of 46 in 138898.

Moving on to step 1:
When dividing 1 by 46, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 46

Let's proceed to step 2:
The number 46 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 46

Let's proceed to step 3:
When dividing 138 by 46, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 138 from 138 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 46

Advancing to step 4:
46 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 8, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 46

Step 5:
89 divided by 46 is 1 with a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 301.0
The remainder is 43 after subtracting 46 from 89.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 46

Moving on to step 6:
The number 46 fits into 438 9 times, leaving a remainder of 24.
The next digit of our result is 9. 
Result so far: 3019.0
If we take 414 away from 438, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
If we divide 240 by 46, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3019.5
The remainder is 10 after subtracting 230 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 46, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3019.52
Deduct 92 from 100 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
80 divided by 46 is 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 3019.521
If we subtract 46 from 80, 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.

Step 10:
If we divide 340 by 46, we get 7 and a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 3019.5217
The remainder is 18 after subtracting 322 from 340.
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 11:
The number 46 fits into 180 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 3019.52173
Deduct 138 from 180 and we're left with 42.
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 12:
420 divided by 46 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 3019.521739
If we take 414 away from 420, we end up 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.

Advancing to step 13:
46 goes into 60 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 3019.5217391
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.

Step 14:
When dividing 140 by 46, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3019.52173913
If we take 138 away from 140, we end up 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.

The final result is 3019.52173913 with a remainder of 2e-09.
