129401 ÷ 65 
We want to divide 129401 by 65.

Going ahead to step 1:
If we divide 1 by 65, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 65

On to step 2:
65 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
Subtracting 0 from 12 leaves us with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 65

Let's proceed to step 3:
65 can be fit into 129 1 times, resulting in a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 65 from 129 to get 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 65

Let's proceed to step 4:
65 goes into 644 9 times with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 59 after subtracting 585 from 644.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 65

Moving on to step 5:
65 can be fit into 590 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 199.0
The remainder is 5 after subtracting 585 from 590.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 65

Advancing to step 6:
65 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 1990.0
If we subtract 0 from 51, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
65 goes into 510 7 times with a remainder of 55.
The next digit of our result is 7. 
Result so far: 1990.7
Subtracting 455 from 510 leaves us with 55.
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 8:
65 can be fit into 550 8 times, resulting in a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 1990.78
Deduct 520 from 550 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
The number 65 fits into 300 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 1990.784
Subtracting 260 from 300 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
When dividing 400 by 65, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 1990.7846
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
65 goes into 100 1 times with a remainder of 35.
The next digit of our result is 1. 
Result so far: 1990.78461
If we take 65 away from 100, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
When dividing 350 by 65, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1990.784615
If we take 325 away from 350, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 13:
65 can be fit into 250 3 times, resulting in a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 1990.7846153
The remainder is 55 after subtracting 195 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 14:
65 goes into 550 8 times with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 1990.78461538
Deduct 520 from 550 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 1990.78461538 with a remaining 3e-08.
