29129 ÷ 61 
The aim is to understand the frequency of 61 in 29129.

Advancing to step 1:
61 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 61

Step 2:
The number 61 fits into 29 0 times, leaving a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 61

Moving on to step 3:
When dividing 291 by 61, we get 4 with a remainder of 47.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 47 after subtracting 244 from 291.
Include the next digit (2) from the dividend after 47, then repeat: 472 / 61

Advancing to step 4:
If we divide 472 by 61, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtract 427 from 472 to get 45.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 61

Advancing to step 5:
The number 61 fits into 459 7 times, leaving a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 477.0
Subtracting 427 from 459 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 6:
320 divided by 61 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 477.5
Deduct 305 from 320 and we're left with 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 7:
If we divide 150 by 61, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 477.52
Deduct 122 from 150 and we're left 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.

Going ahead to step 8:
61 goes into 280 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 477.524
Subtracting 244 from 280 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
61 goes into 360 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 477.5245
The remainder is 55 after subtracting 305 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
The number 61 fits into 550 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 477.52459
Deduct 549 from 550 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.

Moving on to step 11:
When dividing 10 by 61, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 477.52459
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.

Moving on to step 12:
When dividing 100 by 61, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 477.5245901
The remainder is 39 after subtracting 61 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
If we divide 390 by 61, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 477.52459016
Deduct 366 from 390 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.

After the division, we end up with 477.52459016 and a remainder of 2.4e-08.
