129031 ÷ 61 
The aim is to understand the frequency of 61 in 129031.

On to step 1:
The number 61 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 61

Going ahead to step 2:
When dividing 12 by 61, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 61

Going ahead to step 3:
61 can be fit into 129 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 122 from 129 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 61

Going ahead to step 4:
61 can be fit into 70 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 61 away from 70, we end up with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 61

Advancing to step 5:
61 goes into 93 1 times with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
The remainder is 32 after subtracting 61 from 93.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 61

Moving on to step 6:
If we divide 321 by 61, we get 5 and a remainder of 16.
The next digit of our result is 5. 
Result so far: 2115.0
If we subtract 305 from 321, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
When dividing 160 by 61, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 2115.2
If we take 122 away from 160, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
380 divided by 61 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 2115.26
Deduct 366 from 380 and we're left 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.

Moving on to step 9:
61 goes into 140 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2115.262
Subtracting 122 from 140 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
61 goes into 180 2 times with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 2115.2622
Subtracting 122 from 180 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 2115.2622 and a remainder of 0.00058.
