We're dividing 23084988 by 643 
We're looking to find how many times 643 goes into 23084988.

On to step 1:
643 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 643

Let's proceed to step 2:
643 can be fit into 23 0 times, resulting in a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 643

Moving on to step 3:
If we divide 230 by 643, we get 0 and a remainder of 230.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 230 to get 230.
Append the next digit (8) from the dividend to 230 and continue with: 2308 / 643

On to step 4:
643 can be fit into 2308 3 times, resulting in a remainder of 379.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 1929 from 2308 to get 379.
Fetch the next digit (4) from the dividend, attach it to 379 and continue: 3794 / 643

On to step 5:
If we divide 3794 by 643, we get 5 and a remainder of 579.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 579 after subtracting 3215 from 3794.
Fetch the next digit (9) from the dividend, attach it to 579 and continue: 5799 / 643

On to step 6:
5799 divided by 643 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 359.0
Subtract 5787 from 5799 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 643

Going ahead to step 7:
643 can be fit into 128 0 times, resulting in a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 3590.0
Subtract 0 from 128 to get 128.
Bring next digit (8) of the dividend behind the 128 and repeat the process: 1288 / 643

Step 8:
The number 643 fits into 1288 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 35902.0
Deduct 1286 from 1288 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 643, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 35902.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
If we divide 200 by 643, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 35902.0
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 35902.0 with a remainder of 0.2.
