We look at the division of 81801485 by 289 
Let's see how many times 289 fits into 81801485.

Going ahead to step 1:
The number 289 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 289

Advancing to step 2:
289 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 289

On to step 3:
The number 289 fits into 818 2 times, leaving a remainder of 240.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 578 from 818, we get 240.
Fetch the next digit (0) from the dividend, attach it to 240 and continue: 2400 / 289

Going ahead to step 4:
289 can be fit into 2400 8 times, resulting in a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 2312 from 2400 leaves us with 88.
Bring next digit (1) of the dividend behind the 88 and repeat the process: 881 / 289

Moving on to step 5:
289 can be fit into 881 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 283.0
The remainder is 14 after subtracting 867 from 881.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 289

On to step 6:
When dividing 144 by 289, we get 0 with a remainder of 144.
Put 0 as the next digit of the answer. 
Result so far: 2830.0
Subtracting 0 from 144 leaves us with 144.
Take the next digit (8) from the dividend and append it to 144, then repeat: 1448 / 289

Step 7:
289 can be fit into 1448 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 28305.0
If we take 1445 away from 1448, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 289

Let's proceed to step 8:
If we divide 35 by 289, we get 0 and a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 283050.0
Deduct 0 from 35 and we're left 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.

On to step 9:
If we divide 350 by 289, we get 1 and a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 283050.1
Subtract 289 from 350 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 10:
289 goes into 610 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 283050.12
If we take 578 away from 610, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
289 goes into 320 1 times with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 283050.121
Subtract 289 from 320 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
289 goes into 310 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 283050.1211
The remainder is 21 after subtracting 289 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 283050.1211 and a remainder of 0.00021.
