44261907 ÷ 645 
We want to divide 44261907 by 645.

Let's proceed to step 1:
When dividing 4 by 645, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 645

Let's proceed to step 2:
645 goes into 44 0 times with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Append the next digit (2) from the dividend to 44 and continue with: 442 / 645

Going ahead to step 3:
645 goes into 442 0 times with a remainder of 442.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 442, we get 442.
Fetch the next digit (6) from the dividend, attach it to 442 and continue: 4426 / 645

Step 4:
The number 645 fits into 4426 6 times, leaving a remainder of 556.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 3870 from 4426 and we're left with 556.
Grab the next digit (1) from the dividend, add it to 556, then carry on: 5561 / 645

Going ahead to step 5:
When dividing 5561 by 645, we get 8 with a remainder of 401.
Put 8 as the next digit of the answer. 
Result so far: 68.0
The remainder is 401 after subtracting 5160 from 5561.
Take the next digit (9) from the dividend and append it to 401, then repeat: 4019 / 645

Going ahead to step 6:
If we divide 4019 by 645, we get 6 and a remainder of 149.
The number 6 becomes the next digit in our result. 
Result so far: 686.0
Subtracting 3870 from 4019 leaves us with 149.
Grab the next digit (0) from the dividend, add it to 149, then carry on: 1490 / 645

Moving on to step 7:
645 can be fit into 1490 2 times, resulting in a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 6862.0
Subtracting 1290 from 1490 leaves us with 200.
Take the next digit (7) from the dividend and append it to 200, then repeat: 2007 / 645

Moving on to step 8:
2007 divided by 645 is 3 with a remainder of 72.
The number 3 becomes the next digit in our result. 
Result so far: 68623.0
If we take 1935 away from 2007, we end up with 72.
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:
When dividing 720 by 645, we get 1 with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 68623.1
Deduct 645 from 720 and we're left 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.

Moving on to step 10:
When dividing 750 by 645, we get 1 with a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 68623.11
If we take 645 away from 750, we end up 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.

Our division results in 68623.11 with a remaining 0.105.
