We divide 129438 by 46
The aim is to understand the frequency of 46 in 129438.

Going ahead to step 1:
1 divided by 46 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 46

Step 2:
46 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 46

Advancing to step 3:
46 goes into 129 2 times with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 92 from 129 to get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 46

Advancing to step 4:
When dividing 374 by 46, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 368 from 374, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 46

Step 5:
When dividing 63 by 46, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
The remainder is 17 after subtracting 46 from 63.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 46

Let's proceed to step 6:
46 can be fit into 178 3 times, resulting in a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 2813.0
Subtract 138 from 178 to get 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 7:
46 can be fit into 400 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 2813.8
If we take 368 away from 400, we end up 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.

Moving on to step 8:
320 divided by 46 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2813.86
If we take 276 away from 320, we end up 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.

On to step 9:
46 goes into 440 9 times with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 2813.869
Deduct 414 from 440 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
When dividing 260 by 46, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2813.8695
Deduct 230 from 260 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
300 divided by 46 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 2813.86956
The remainder is 24 after subtracting 276 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
The number 46 fits into 240 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 2813.869565
If we subtract 230 from 240, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
100 divided by 46 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2813.8695652
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.

Step 14:
If we divide 80 by 46, we get 1 and a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 2813.86956521
If we take 46 away from 80, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 2813.86956521, with a leftover of 3.4e-08.
