48724662 ÷ 645 
Let's see how many times 645 fits into 48724662.

Advancing to step 1:
The number 645 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 645

Advancing to step 2:
645 goes into 48 0 times with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 645

Going ahead to step 3:
645 can be fit into 487 0 times, resulting in a remainder of 487.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 487, we get 487.
Append the next digit (2) from the dividend to 487 and continue with: 4872 / 645

Advancing to step 4:
645 can be fit into 4872 7 times, resulting in a remainder of 357.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 4515 from 4872, we get 357.
Grab the next digit (4) from the dividend, add it to 357, then carry on: 3574 / 645

Let's proceed to step 5:
When dividing 3574 by 645, we get 5 with a remainder of 349.
The next digit of our result is 5. 
Result so far: 75.0
If we subtract 3225 from 3574, we get 349.
Append the next digit (6) from the dividend to 349 and continue with: 3496 / 645

Going ahead to step 6:
If we divide 3496 by 645, we get 5 and a remainder of 271.
The next digit of our result is 5. 
Result so far: 755.0
Deduct 3225 from 3496 and we're left with 271.
Take the next digit (6) from the dividend and append it to 271, then repeat: 2716 / 645

On to step 7:
645 can be fit into 2716 4 times, resulting in a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 7554.0
If we subtract 2580 from 2716, we get 136.
Take the next digit (2) from the dividend and append it to 136, then repeat: 1362 / 645

Moving on to step 8:
645 goes into 1362 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 75542.0
The remainder is 72 after subtracting 1290 from 1362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
If we divide 720 by 645, we get 1 and a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 75542.1
If we take 645 away from 720, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 10:
645 can be fit into 750 1 times, resulting in a remainder of 105.
Record the quotient 1 as the next digit in the result. 
Result so far: 75542.11
Subtracting 645 from 750 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 75542.11 with a remainder of 0.105.
