Let's divide 129072 by 61
We're looking to find how many times 61 goes into 129072.

Going ahead to step 1:
If we divide 1 by 61, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 61

On to step 2:
61 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 61

Advancing to step 3:
61 goes into 129 2 times with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 122 away from 129, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 61

Step 4:
61 goes into 70 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 9 after subtracting 61 from 70.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 61

Step 5:
When dividing 97 by 61, we get 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Subtract 61 from 97 to get 36.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 61

Going ahead to step 6:
61 goes into 362 5 times with a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 2115.0
Subtract 305 from 362 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
The number 61 fits into 570 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 2115.9
Deduct 549 from 570 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
When dividing 210 by 61, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 2115.93
Deduct 183 from 210 and we're left 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 9:
When dividing 270 by 61, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 2115.934
Deduct 244 from 270 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
61 goes into 260 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 2115.9344
Subtracting 244 from 260 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 2115.9344, with a leftover of 0.00016.
