24482179 ÷ 645 
We want to divide 24482179 by 645.

On to step 1:
If we divide 2 by 645, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 645

Step 2:
When dividing 24 by 645, we get 0 with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 645

Step 3:
The number 645 fits into 244 0 times, leaving a remainder of 244.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 244, we get 244.
Include the next digit (8) from the dividend after 244, then repeat: 2448 / 645

Moving on to step 4:
645 goes into 2448 3 times with a remainder of 513.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1935 from 2448 leaves us with 513.
Take the next digit (2) from the dividend and append it to 513, then repeat: 5132 / 645

Advancing to step 5:
If we divide 5132 by 645, we get 7 and a remainder of 617.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtract 4515 from 5132 to get 617.
Take the next digit (1) from the dividend and append it to 617, then repeat: 6171 / 645

On to step 6:
6171 divided by 645 is 9 with a remainder of 366.
Write down 9 as next digit of the result. 
Result so far: 379.0
Subtract 5805 from 6171 to get 366.
Append the next digit (7) from the dividend to 366 and continue with: 3667 / 645

Moving on to step 7:
645 goes into 3667 5 times with a remainder of 442.
The number 5 becomes the next digit in our result. 
Result so far: 3795.0
Subtract 3225 from 3667 to get 442.
Fetch the next digit (9) from the dividend, attach it to 442 and continue: 4429 / 645

Moving on to step 8:
When dividing 4429 by 645, we get 6 with a remainder of 559.
The next digit of our result is 6. 
Result so far: 37956.0
Subtracting 3870 from 4429 leaves us with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Going ahead to step 9:
When dividing 5590 by 645, we get 8 with a remainder of 430.
The next digit of our result is 8. 
Result so far: 37956.8
Deduct 5160 from 5590 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 10:
4300 divided by 645 is 6 with a remainder of 430.
Use 6 as the next digit of our solution. 
Result so far: 37956.86
If we take 3870 away from 4300, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 11:
The number 645 fits into 4300 6 times, leaving a remainder of 430.
The number 6 becomes the next digit in our result. 
Result so far: 37956.866
Subtract 3870 from 4300 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Our division results in 37956.866 with a remaining 0.043.
