48524259 ÷ 645 
Let's see how many times 645 fits into 48524259.

Let's proceed to step 1:
If we divide 4 by 645, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 645

Step 2:
645 can be fit into 48 0 times, resulting in a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 645

On to step 3:
645 goes into 485 0 times with a remainder of 485.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 485, we end up with 485.
Include the next digit (2) from the dividend after 485, then repeat: 4852 / 645

On to step 4:
645 goes into 4852 7 times with a remainder of 337.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 4515 from 4852 and we're left with 337.
Append the next digit (4) from the dividend to 337 and continue with: 3374 / 645

On to step 5:
If we divide 3374 by 645, we get 5 and a remainder of 149.
The next digit of our result is 5. 
Result so far: 75.0
If we subtract 3225 from 3374, we get 149.
Bring next digit (2) of the dividend behind the 149 and repeat the process: 1492 / 645

Going ahead to step 6:
The number 645 fits into 1492 2 times, leaving a remainder of 202.
Write down 2 as next digit of the result. 
Result so far: 752.0
Subtract 1290 from 1492 to get 202.
Bring next digit (5) of the dividend behind the 202 and repeat the process: 2025 / 645

On to step 7:
645 goes into 2025 3 times with a remainder of 90.
Use 3 as the next digit of our solution. 
Result so far: 7523.0
If we subtract 1935 from 2025, we get 90.
Take the next digit (9) from the dividend and append it to 90, then repeat: 909 / 645

Let's proceed to step 8:
The number 645 fits into 909 1 times, leaving a remainder of 264.
The next digit of our result is 1. 
Result so far: 75231.0
If we take 645 away from 909, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 9:
If we divide 2640 by 645, we get 4 and a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 75231.4
Deduct 2580 from 2640 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 645, we get 0 and a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 75231.4
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 11:
645 goes into 6000 9 times with a remainder of 195.
The number 9 becomes the next digit in our result. 
Result so far: 75231.409
If we subtract 5805 from 6000, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 12:
645 can be fit into 1950 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 75231.4093
The remainder is 15 after subtracting 1935 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
The number 645 fits into 150 0 times, leaving a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 75231.4093
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 14:
The number 645 fits into 1500 2 times, leaving a remainder of 210.
Use 2 as the next digit of our solution. 
Result so far: 75231.409302
The remainder is 210 after subtracting 1290 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 15:
2100 divided by 645 is 3 with a remainder of 165.
Record the quotient 3 as the next digit in the result. 
Result so far: 75231.4093023
If we take 1935 away from 2100, we end up 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 16:
1650 divided by 645 is 2 with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 75231.40930232
Subtract 1290 from 1650 to 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.

Our division results in 75231.40930232 with a remaining 3.6e-07.
