We divide 50175712 by 639
We want to figure out the number of times 50175712 can be divided by 639.

Moving on to step 1:
639 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 639

Advancing to step 2:
The number 639 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 639

Going ahead to step 3:
501 divided by 639 is 0 with a remainder of 501.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 501 and we're left with 501.
Grab the next digit (7) from the dividend, add it to 501, then carry on: 5017 / 639

Let's proceed to step 4:
639 goes into 5017 7 times with a remainder of 544.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 4473 from 5017 leaves us with 544.
Include the next digit (5) from the dividend after 544, then repeat: 5445 / 639

On to step 5:
When dividing 5445 by 639, we get 8 with a remainder of 333.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 5112 from 5445 and we're left with 333.
Fetch the next digit (7) from the dividend, attach it to 333 and continue: 3337 / 639

Advancing to step 6:
639 can be fit into 3337 5 times, resulting in a remainder of 142.
Put 5 as the next digit of the answer. 
Result so far: 785.0
Subtract 3195 from 3337 to get 142.
Append the next digit (1) from the dividend to 142 and continue with: 1421 / 639

Moving on to step 7:
1421 divided by 639 is 2 with a remainder of 143.
The next digit of our result is 2. 
Result so far: 7852.0
Subtract 1278 from 1421 to get 143.
Fetch the next digit (2) from the dividend, attach it to 143 and continue: 1432 / 639

Step 8:
639 goes into 1432 2 times with a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 78522.0
If we subtract 1278 from 1432, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 9:
The number 639 fits into 1540 2 times, leaving a remainder of 262.
Use 2 as the next digit of our solution. 
Result so far: 78522.2
If we take 1278 away from 1540, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 10:
The number 639 fits into 2620 4 times, leaving a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 78522.24
The remainder is 64 after subtracting 2556 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
If we divide 640 by 639, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 78522.241
If we subtract 639 from 640, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
639 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 78522.241
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
When dividing 100 by 639, we get 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 78522.241
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 78522.241 with a remainder of 0.0001.
