398312 ÷ 29 
The aim is to understand the frequency of 29 in 398312.

Going ahead to step 1:
If we divide 3 by 29, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 29

On to 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
Subtracting 29 from 39 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 29

Going ahead to step 3:
If we divide 108 by 29, we get 3 and a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 87 from 108 leaves us with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 29

Advancing to step 4:
When dividing 213 by 29, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 137.0
Deduct 203 from 213 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 29

Let's proceed to step 5:
The number 29 fits into 101 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 1373.0
Deduct 87 from 101 and we're left with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 29

Advancing to step 6:
When dividing 142 by 29, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 13734.0
If we take 116 away from 142, we end up 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.

Advancing to step 7:
When dividing 260 by 29, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 13734.8
Subtracting 232 from 260 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
The number 29 fits into 280 9 times, leaving a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 13734.89
If we take 261 away from 280, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
190 divided by 29 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 13734.896
Subtracting 174 from 190 leaves us 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.

Moving on to step 10:
160 divided by 29 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 13734.8965
If we subtract 145 from 160, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
29 can be fit into 150 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 13734.89655
Deduct 145 from 150 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 13734.89655 with a remainder of 5e-06.
