21836871 ÷ 289 
Our goal is to divide 21836871 by 289.

Advancing to step 1:
2 divided by 289 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 289

Moving on to step 2:
289 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 289

Moving on to step 3:
When dividing 218 by 289, we get 0 with a remainder of 218.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 218, we get 218.
Fetch the next digit (3) from the dividend, attach it to 218 and continue: 2183 / 289

Moving on to step 4:
If we divide 2183 by 289, we get 7 and a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 2023 from 2183 and we're left with 160.
Append the next digit (6) from the dividend to 160 and continue with: 1606 / 289

Advancing to step 5:
289 can be fit into 1606 5 times, resulting in a remainder of 161.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtracting 1445 from 1606 leaves us with 161.
Take the next digit (8) from the dividend and append it to 161, then repeat: 1618 / 289

Let's proceed to step 6:
289 goes into 1618 5 times with a remainder of 173.
Write down 5 as next digit of the result. 
Result so far: 755.0
If we subtract 1445 from 1618, we get 173.
Fetch the next digit (7) from the dividend, attach it to 173 and continue: 1737 / 289

Advancing to step 7:
If we divide 1737 by 289, we get 6 and a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 7556.0
If we take 1734 away from 1737, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 289

Advancing to step 8:
The number 289 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 75560.0
If we subtract 0 from 31, we 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.

Let's proceed to step 9:
The number 289 fits into 310 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 75560.1
Subtracting 289 from 310 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
289 can be fit into 210 0 times, resulting in a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 75560.1
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 11:
The number 289 fits into 2100 7 times, leaving a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 75560.107
The remainder is 77 after subtracting 2023 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 12:
The number 289 fits into 770 2 times, leaving a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 75560.1072
Deduct 578 from 770 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 13:
289 can be fit into 1920 6 times, resulting in a remainder of 186.
Put 6 as the next digit of the answer. 
Result so far: 75560.10726
If we subtract 1734 from 1920, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 14:
When dividing 1860 by 289, we get 6 with a remainder of 126.
Use 6 as the next digit of our solution. 
Result so far: 75560.107266
Subtract 1734 from 1860 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

In conclusion, the division gives 75560.107266 with a balance of 1.26e-05.
