49832057 ÷ 645 
Let's see how many times 645 fits into 49832057.

Moving on to step 1:
The number 645 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 645

Going ahead to step 2:
49 divided by 645 is 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 645

Advancing to step 3:
The number 645 fits into 498 0 times, leaving a remainder of 498.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 498 and we're left with 498.
Take the next digit (3) from the dividend and append it to 498, then repeat: 4983 / 645

Advancing to step 4:
If we divide 4983 by 645, we get 7 and a remainder of 468.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 4515 from 4983, we get 468.
Fetch the next digit (2) from the dividend, attach it to 468 and continue: 4682 / 645

Advancing to step 5:
If we divide 4682 by 645, we get 7 and a remainder of 167.
Use 7 as the next digit of our solution. 
Result so far: 77.0
The remainder is 167 after subtracting 4515 from 4682.
Take the next digit (0) from the dividend and append it to 167, then repeat: 1670 / 645

Let's proceed to step 6:
645 goes into 1670 2 times with a remainder of 380.
Record the quotient 2 as the next digit in the result. 
Result so far: 772.0
The remainder is 380 after subtracting 1290 from 1670.
Bring next digit (5) of the dividend behind the 380 and repeat the process: 3805 / 645

Moving on to step 7:
645 can be fit into 3805 5 times, resulting in a remainder of 580.
The number 5 becomes the next digit in our result. 
Result so far: 7725.0
Subtracting 3225 from 3805 leaves us with 580.
Grab the next digit (7) from the dividend, add it to 580, then carry on: 5807 / 645

On to step 8:
645 goes into 5807 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 77259.0
If we subtract 5805 from 5807, we get 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:
645 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 77259.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
200 divided by 645 is 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 77259.0
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 outcome is 77259.0, with a leftover of 0.2.
