We're dividing 21745517 by 289 
Our goal is to divide 21745517 by 289.

Going ahead to step 1:
If we divide 2 by 289, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 289

Moving on to step 2:
289 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 289

Advancing to step 3:
217 divided by 289 is 0 with a remainder of 217.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 217, we end up with 217.
Grab the next digit (4) from the dividend, add it to 217, then carry on: 2174 / 289

Going ahead to step 4:
2174 divided by 289 is 7 with a remainder of 151.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 151 after subtracting 2023 from 2174.
Bring next digit (5) of the dividend behind the 151 and repeat the process: 1515 / 289

Step 5:
If we divide 1515 by 289, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Deduct 1445 from 1515 and we're left with 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 289

Going ahead to step 6:
289 goes into 705 2 times with a remainder of 127.
Put 2 as the next digit of the answer. 
Result so far: 752.0
If we take 578 away from 705, we end up with 127.
Fetch the next digit (1) from the dividend, attach it to 127 and continue: 1271 / 289

Moving on to step 7:
289 can be fit into 1271 4 times, resulting in a remainder of 115.
Use 4 as the next digit of our solution. 
Result so far: 7524.0
If we subtract 1156 from 1271, we get 115.
Grab the next digit (7) from the dividend, add it to 115, then carry on: 1157 / 289

Going ahead to step 8:
If we divide 1157 by 289, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 75244.0
Subtracting 1156 from 1157 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
If we divide 10 by 289, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 75244.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
289 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 75244.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 75244.0 with a remainder of 0.1.
