We divide 403913 by 29
The aim is to understand the frequency of 29 in 403913.

Step 1:
4 divided by 29 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 29

Advancing to step 2:
If we divide 40 by 29, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 29 away from 40, we end up with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 29

Going ahead to step 3:
The number 29 fits into 113 3 times, leaving a remainder of 26.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 87 from 113 leaves us with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 29

Moving on to step 4:
When dividing 269 by 29, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
The remainder is 8 after subtracting 261 from 269.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 29

Moving on to step 5:
29 goes into 81 2 times with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 1392.0
If we take 58 away from 81, we end up with 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 29

Let's proceed to step 6:
233 divided by 29 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 13928.0
Subtracting 232 from 233 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 29 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13928.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 29 fits into 100 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 13928.03
Deduct 87 from 100 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
The number 29 fits into 130 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 13928.034
Deduct 116 from 130 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.

On to step 10:
When dividing 140 by 29, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 13928.0344
The remainder is 24 after subtracting 116 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 13928.0344 with a remaining 0.00024.
