41459336 ÷ 645 
We want to figure out the number of times 41459336 can be divided by 645.

Let's proceed to step 1:
4 divided by 645 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 645

Moving on to step 2:
645 goes into 41 0 times with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 645

Advancing to step 3:
The number 645 fits into 414 0 times, leaving a remainder of 414.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 414 after subtracting 0 from 414.
Bring next digit (5) of the dividend behind the 414 and repeat the process: 4145 / 645

Advancing to step 4:
4145 divided by 645 is 6 with a remainder of 275.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 3870 from 4145 and we're left with 275.
Fetch the next digit (9) from the dividend, attach it to 275 and continue: 2759 / 645

Advancing to step 5:
The number 645 fits into 2759 4 times, leaving a remainder of 179.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 2580 from 2759 leaves us with 179.
Fetch the next digit (3) from the dividend, attach it to 179 and continue: 1793 / 645

Going ahead to step 6:
645 goes into 1793 2 times with a remainder of 503.
Write down 2 as next digit of the result. 
Result so far: 642.0
Deduct 1290 from 1793 and we're left with 503.
Bring next digit (3) of the dividend behind the 503 and repeat the process: 5033 / 645

On to step 7:
645 can be fit into 5033 7 times, resulting in a remainder of 518.
Record the quotient 7 as the next digit in the result. 
Result so far: 6427.0
The remainder is 518 after subtracting 4515 from 5033.
Bring next digit (6) of the dividend behind the 518 and repeat the process: 5186 / 645

Moving on to step 8:
When dividing 5186 by 645, we get 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 64278.0
Subtract 5160 from 5186 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
When dividing 260 by 645, we get 0 with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 64278.0
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
The number 645 fits into 2600 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 64278.04
If we take 2580 away from 2600, we end up 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.

Moving on to step 11:
When dividing 200 by 645, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 64278.04
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
The number 645 fits into 2000 3 times, leaving a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 64278.0403
Deduct 1935 from 2000 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 13:
The number 645 fits into 650 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 64278.04031
Deduct 645 from 650 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
645 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 64278.04031
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 15:
500 divided by 645 is 0 with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 64278.04031
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 64278.04031, with a leftover of 5e-06.
