50160037 ÷ 643 
Let's see how many times 643 fits into 50160037.

Moving on to step 1:
643 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 643

On to step 2:
50 divided by 643 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 643

On to step 3:
643 goes into 501 0 times with a remainder of 501.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 501 leaves us with 501.
Bring next digit (6) of the dividend behind the 501 and repeat the process: 5016 / 643

Let's proceed to step 4:
When dividing 5016 by 643, we get 7 with a remainder of 515.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 4501 from 5016 and we're left with 515.
Grab the next digit (0) from the dividend, add it to 515, then carry on: 5150 / 643

Let's proceed to step 5:
The number 643 fits into 5150 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 5144 from 5150 to get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 643

Going ahead to step 6:
When dividing 60 by 643, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
Subtracting 0 from 60 leaves us with 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 643

Going ahead to step 7:
When dividing 603 by 643, we get 0 with a remainder of 603.
The next digit of our result is 0. 
Result so far: 7800.0
Deduct 0 from 603 and we're left with 603.
Append the next digit (7) from the dividend to 603 and continue with: 6037 / 643

On to step 8:
When dividing 6037 by 643, we get 9 with a remainder of 250.
The number 9 becomes the next digit in our result. 
Result so far: 78009.0
The remainder is 250 after subtracting 5787 from 6037.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 9:
2500 divided by 643 is 3 with a remainder of 571.
Write down 3 as next digit of the result. 
Result so far: 78009.3
Subtracting 1929 from 2500 leaves us with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Advancing to step 10:
643 can be fit into 5710 8 times, resulting in a remainder of 566.
The next digit of our result is 8. 
Result so far: 78009.38
Deduct 5144 from 5710 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Step 11:
5660 divided by 643 is 8 with a remainder of 516.
Write down 8 as next digit of the result. 
Result so far: 78009.388
If we subtract 5144 from 5660, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

After the division, we end up with 78009.388 and a remainder of 0.0516.
