We're dividing 41330649 by 645 
We want to divide 41330649 by 645.

Advancing to step 1:
The number 645 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 645

Step 2:
The number 645 fits into 41 0 times, leaving a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 645

Let's proceed to step 3:
645 can be fit into 413 0 times, resulting in a remainder of 413.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 413 and we're left with 413.
Fetch the next digit (3) from the dividend, attach it to 413 and continue: 4133 / 645

Going ahead to step 4:
645 can be fit into 4133 6 times, resulting in a remainder of 263.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 3870 away from 4133, we end up with 263.
Include the next digit (0) from the dividend after 263, then repeat: 2630 / 645

Advancing to step 5:
645 can be fit into 2630 4 times, resulting in a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Deduct 2580 from 2630 and we're left with 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 645

On to step 6:
645 can be fit into 506 0 times, resulting in a remainder of 506.
Record the quotient 0 as the next digit in the result. 
Result so far: 640.0
If we take 0 away from 506, we end up with 506.
Grab the next digit (4) from the dividend, add it to 506, then carry on: 5064 / 645

Advancing to step 7:
645 goes into 5064 7 times with a remainder of 549.
Write down 7 as next digit of the result. 
Result so far: 6407.0
The remainder is 549 after subtracting 4515 from 5064.
Append the next digit (9) from the dividend to 549 and continue with: 5499 / 645

On to step 8:
645 goes into 5499 8 times with a remainder of 339.
The number 8 becomes the next digit in our result. 
Result so far: 64078.0
If we subtract 5160 from 5499, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 9:
The number 645 fits into 3390 5 times, leaving a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 64078.5
Deduct 3225 from 3390 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 10:
645 goes into 1650 2 times with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 64078.52
If we subtract 1290 from 1650, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 11:
645 can be fit into 3600 5 times, resulting in a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 64078.525
If we take 3225 away from 3600, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 12:
When dividing 3750 by 645, we get 5 with a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 64078.5255
Subtracting 3225 from 3750 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

The final outcome is 64078.5255, with a leftover of 0.00525.
