1289400 ÷ 329 
Our goal is to divide 1289400 by 329.

Step 1:
1 divided by 329 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 329

Step 2:
If we divide 12 by 329, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 329

Let's proceed to step 3:
When dividing 128 by 329, we get 0 with a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Fetch the next digit (9) from the dividend, attach it to 128 and continue: 1289 / 329

Step 4:
When dividing 1289 by 329, we get 3 with a remainder of 302.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 987 from 1289 to get 302.
Take the next digit (4) from the dividend and append it to 302, then repeat: 3024 / 329

Step 5:
329 goes into 3024 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 2961 from 3024, we get 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 329

Let's proceed to step 6:
If we divide 630 by 329, we get 1 and a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 391.0
Subtracting 329 from 630 leaves us with 301.
Bring next digit (0) of the dividend behind the 301 and repeat the process: 3010 / 329

Step 7:
329 goes into 3010 9 times with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 3919.0
Deduct 2961 from 3010 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 8:
329 goes into 490 1 times with a remainder of 161.
Write down 1 as next digit of the result. 
Result so far: 3919.1
If we subtract 329 from 490, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 9:
329 goes into 1610 4 times with a remainder of 294.
Write down 4 as next digit of the result. 
Result so far: 3919.14
Subtracting 1316 from 1610 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 10:
329 goes into 2940 8 times with a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 3919.148
If we subtract 2632 from 2940, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 11:
329 can be fit into 3080 9 times, resulting in a remainder of 119.
The number 9 becomes the next digit in our result. 
Result so far: 3919.1489
Subtracting 2961 from 3080 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 12:
The number 329 fits into 1190 3 times, leaving a remainder of 203.
The number 3 becomes the next digit in our result. 
Result so far: 3919.14893
Subtracting 987 from 1190 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 13:
If we divide 2030 by 329, we get 6 and a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 3919.148936
Subtract 1974 from 2030 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
The number 329 fits into 560 1 times, leaving a remainder of 231.
The number 1 becomes the next digit in our result. 
Result so far: 3919.1489361
If we take 329 away from 560, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 15:
329 goes into 2310 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 3919.14893617
Subtract 2303 from 2310 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 3919.14893617 with a remaining 7e-09.
