Let's divide 38437889 by 29
The aim is to understand the frequency of 29 in 38437889.

Going ahead to step 1:
If we divide 3 by 29, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 29

Advancing to step 2:
When dividing 38 by 29, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 29 from 38 leaves us with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 29

On to step 3:
If we divide 94 by 29, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 87 from 94 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 29

Let's proceed to step 4:
29 goes into 73 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
If we take 58 away from 73, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 29

Going ahead to step 5:
When dividing 157 by 29, we get 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 1325.0
The remainder is 12 after subtracting 145 from 157.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 29

Moving on to step 6:
The number 29 fits into 128 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 13254.0
The remainder is 12 after subtracting 116 from 128.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 29

Step 7:
The number 29 fits into 128 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 132544.0
The remainder is 12 after subtracting 116 from 128.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 29

Let's proceed to step 8:
29 goes into 129 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 1325444.0
The remainder is 13 after subtracting 116 from 129.
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 9:
When dividing 130 by 29, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 1325444.4
If we subtract 116 from 130, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
The number 29 fits into 140 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 1325444.44
Deduct 116 from 140 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 1325444.44, with a leftover of 0.024.
