We divide 391972 by 29
The aim is to understand the frequency of 29 in 391972.

Going ahead to step 1:
3 divided by 29 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 29

Going ahead to step 2:
When dividing 39 by 29, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 10 after subtracting 29 from 39.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 29

Let's proceed to step 3:
101 divided by 29 is 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 14 after subtracting 87 from 101.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 29

Advancing to step 4:
29 goes into 149 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Subtract 145 from 149 to get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 29

Step 5:
When dividing 47 by 29, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1351.0
If we take 29 away from 47, we end up with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 29

Advancing to step 6:
29 goes into 182 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 13516.0
Subtract 174 from 182 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
If we divide 80 by 29, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 13516.2
Subtract 58 from 80 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
If we divide 220 by 29, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 13516.27
Subtract 203 from 220 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
When dividing 170 by 29, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 13516.275
If we subtract 145 from 170, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
29 can be fit into 250 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 13516.2758
The remainder is 18 after subtracting 232 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
180 divided by 29 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 13516.27586
Deduct 174 from 180 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
When dividing 60 by 29, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 13516.275862
Subtracting 58 from 60 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
29 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 13516.275862
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
200 divided by 29 is 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 13516.27586206
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 13516.27586206 with a remaining 2.6e-08.
