We divide 87995200 by 645
Let's see how many times 645 fits into 87995200.

Let's proceed to step 1:
The number 645 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 645

Step 2:
87 divided by 645 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 645

Advancing to step 3:
879 divided by 645 is 1 with a remainder of 234.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 645 away from 879, we end up with 234.
Take the next digit (9) from the dividend and append it to 234, then repeat: 2349 / 645

Moving on to step 4:
If we divide 2349 by 645, we get 3 and a remainder of 414.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1935 from 2349, we get 414.
Fetch the next digit (5) from the dividend, attach it to 414 and continue: 4145 / 645

Advancing to step 5:
The number 645 fits into 4145 6 times, leaving a remainder of 275.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Deduct 3870 from 4145 and we're left with 275.
Include the next digit (2) from the dividend after 275, then repeat: 2752 / 645

Step 6:
2752 divided by 645 is 4 with a remainder of 172.
Use 4 as the next digit of our solution. 
Result so far: 1364.0
Subtracting 2580 from 2752 leaves us with 172.
Bring next digit (0) of the dividend behind the 172 and repeat the process: 1720 / 645

Moving on to step 7:
The number 645 fits into 1720 2 times, leaving a remainder of 430.
The number 2 becomes the next digit in our result. 
Result so far: 13642.0
If we take 1290 away from 1720, we end up with 430.
Fetch the next digit (0) from the dividend, attach it to 430 and continue: 4300 / 645

Step 8:
645 can be fit into 4300 6 times, resulting in a remainder of 430.
The next digit of our result is 6. 
Result so far: 136426.0
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.

Moving on to step 9:
645 can be fit into 4300 6 times, resulting in a remainder of 430.
Use 6 as the next digit of our solution. 
Result so far: 136426.6
Deduct 3870 from 4300 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.

Let's proceed to step 10:
When dividing 4300 by 645, we get 6 with a remainder of 430.
Use 6 as the next digit of our solution. 
Result so far: 136426.66
If we subtract 3870 from 4300, we 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.

The final result is 136426.66 with a remainder of 0.43.
