We look at the division of 31693456 by 29 
The aim is to understand the frequency of 29 in 31693456.

Let's proceed to step 1:
29 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 29

Let's proceed to step 2:
The number 29 fits into 31 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 29 from 31 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 29

Advancing to step 3:
26 divided by 29 is 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 26 after subtracting 0 from 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 29

Step 4:
29 goes into 269 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Subtract 261 from 269 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 29

Step 5:
83 divided by 29 is 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 1092.0
If we subtract 58 from 83, we get 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 29

Going ahead to step 6:
29 can be fit into 254 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 10928.0
The remainder is 22 after subtracting 232 from 254.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 29

Let's proceed to step 7:
When dividing 225 by 29, we get 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 109287.0
Subtract 203 from 225 to get 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 29

Going ahead to step 8:
29 can be fit into 226 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 1092877.0
If we subtract 203 from 226, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
The number 29 fits into 230 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 1092877.7
If we take 203 away from 230, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
270 divided by 29 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 1092877.79
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
29 goes into 90 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1092877.793
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
If we divide 30 by 29, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1092877.7931
The remainder is 1 after subtracting 29 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
When dividing 10 by 29, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1092877.7931
If we subtract 0 from 10, 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.

Moving on to step 14:
29 goes into 100 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 1092877.793103
If we subtract 87 from 100, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 15:
The number 29 fits into 130 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1092877.7931034
Subtracting 116 from 130 leaves us 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.

Let's proceed to step 16:
When dividing 140 by 29, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 1092877.79310344
Subtract 116 from 140 to get 24.
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 1092877.79310344 and a remainder of 2.4e-08.
