We look at the division of 43999386 by 289 
We're looking to find how many times 289 goes into 43999386.

Let's proceed to step 1:
289 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 289

On to step 2:
289 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 289

Advancing to step 3:
When dividing 439 by 289, we get 1 with a remainder of 150.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 289 from 439, we get 150.
Take the next digit (9) from the dividend and append it to 150, then repeat: 1509 / 289

Let's proceed to step 4:
289 goes into 1509 5 times with a remainder of 64.
The next digit of our result is 5. 
Result so far: 15.0
If we take 1445 away from 1509, we end up with 64.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 289

Let's proceed to step 5:
If we divide 649 by 289, we get 2 and a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 152.0
Deduct 578 from 649 and we're left with 71.
Append the next digit (3) from the dividend to 71 and continue with: 713 / 289

Advancing to step 6:
The number 289 fits into 713 2 times, leaving a remainder of 135.
The number 2 becomes the next digit in our result. 
Result so far: 1522.0
Subtract 578 from 713 to get 135.
Append the next digit (8) from the dividend to 135 and continue with: 1358 / 289

Let's proceed to step 7:
If we divide 1358 by 289, we get 4 and a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 15224.0
Subtract 1156 from 1358 to get 202.
Take the next digit (6) from the dividend and append it to 202, then repeat: 2026 / 289

Moving on to step 8:
289 goes into 2026 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 152247.0
Deduct 2023 from 2026 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 289, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 152247.0
Deduct 0 from 30 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.

Let's proceed to step 10:
When dividing 300 by 289, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 152247.01
The remainder is 11 after subtracting 289 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
The number 289 fits into 110 0 times, leaving a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 152247.01
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 12:
1100 divided by 289 is 3 with a remainder of 233.
Use 3 as the next digit of our solution. 
Result so far: 152247.0103
If we subtract 867 from 1100, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 13:
The number 289 fits into 2330 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 152247.01038
Deduct 2312 from 2330 and we're left 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.

Let's proceed to step 14:
The number 289 fits into 180 0 times, leaving a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 152247.01038
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 15:
289 can be fit into 1800 6 times, resulting in a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 152247.0103806
Subtract 1734 from 1800 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 16:
660 divided by 289 is 2 with a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 152247.01038062
Deduct 578 from 660 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The final result is 152247.01038062 with a remainder of 8.2e-08.
