398527 ÷ 29 
The aim is to understand the frequency of 29 in 398527.

Moving on to step 1:
When dividing 3 by 29, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 29

Step 2:
39 divided by 29 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
If we take 29 away from 39, we end up with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 29

Step 3:
29 can be fit into 108 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 87 from 108 leaves us with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 29

Step 4:
If we divide 215 by 29, we get 7 and a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
If we take 203 away from 215, we end up with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 29

On to step 5:
29 goes into 122 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 1374.0
The remainder is 6 after subtracting 116 from 122.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 29

Step 6:
67 divided by 29 is 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 13742.0
Deduct 58 from 67 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
29 goes into 90 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13742.3
Subtracting 87 from 90 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
If we divide 30 by 29, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 13742.31
Deduct 29 from 30 and we're left 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.

Going ahead to step 9:
29 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 13742.31
Subtract 0 from 10 to 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.

On to step 10:
The number 29 fits into 100 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 13742.3103
The remainder is 13 after subtracting 87 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
If we divide 130 by 29, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 13742.31034
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 12:
29 goes into 140 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 13742.310344
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.

After the division, we end up with 13742.310344 and a remainder of 2.4e-06.
