We're dividing 129898 by 40 
We want to figure out the number of times 129898 can be divided by 40.

Going ahead to step 1:
40 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 40

On to step 2:
If we divide 12 by 40, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 40

Moving on to step 3:
129 divided by 40 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 120 from 129 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 40

Step 4:
When dividing 98 by 40, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtract 80 from 98 to get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 40

Let's proceed to step 5:
If we divide 189 by 40, we get 4 and a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 324.0
The remainder is 29 after subtracting 160 from 189.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 40

Step 6:
The number 40 fits into 298 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 3247.0
The remainder is 18 after subtracting 280 from 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 40 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 3247.4
If we subtract 160 from 180, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3247.45
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3247.45
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3247.45
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 3247.45, with a leftover of 0.0.
