We're dividing 21533528 by 289 
We want to figure out the number of times 21533528 can be divided by 289.

Step 1:
2 divided by 289 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 289

Advancing to step 2:
289 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 289

Let's proceed to step 3:
When dividing 215 by 289, we get 0 with a remainder of 215.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 215 leaves us with 215.
Include the next digit (3) from the dividend after 215, then repeat: 2153 / 289

Advancing to step 4:
289 can be fit into 2153 7 times, resulting in a remainder of 130.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 2023 from 2153, we get 130.
Include the next digit (3) from the dividend after 130, then repeat: 1303 / 289

On to step 5:
If we divide 1303 by 289, we get 4 and a remainder of 147.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtract 1156 from 1303 to get 147.
Take the next digit (5) from the dividend and append it to 147, then repeat: 1475 / 289

Step 6:
289 goes into 1475 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 745.0
Subtract 1445 from 1475 to get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 289

Step 7:
289 goes into 302 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 7451.0
Subtracting 289 from 302 leaves us with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 289

On to step 8:
289 can be fit into 138 0 times, resulting in a remainder of 138.
The next digit of our result is 0. 
Result so far: 74510.0
If we subtract 0 from 138, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 9:
289 goes into 1380 4 times with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 74510.4
Subtract 1156 from 1380 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 10:
289 can be fit into 2240 7 times, resulting in a remainder of 217.
The next digit of our result is 7. 
Result so far: 74510.47
The remainder is 217 after subtracting 2023 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 11:
2170 divided by 289 is 7 with a remainder of 147.
The number 7 becomes the next digit in our result. 
Result so far: 74510.477
The remainder is 147 after subtracting 2023 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

The final outcome is 74510.477, with a leftover of 0.0147.
