50125616 ÷ 647 
We want to figure out the number of times 50125616 can be divided by 647.

On to step 1:
647 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 647

On to step 2:
50 divided by 647 is 0 with 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.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 647

Moving on to step 3:
501 divided by 647 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.
Append the next digit (2) from the dividend to 501 and continue with: 5012 / 647

On to step 4:
647 can be fit into 5012 7 times, resulting in a remainder of 483.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 4529 from 5012 to get 483.
Include the next digit (5) from the dividend after 483, then repeat: 4835 / 647

Step 5:
647 goes into 4835 7 times with a remainder of 306.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtracting 4529 from 4835 leaves us with 306.
Take the next digit (6) from the dividend and append it to 306, then repeat: 3066 / 647

Step 6:
3066 divided by 647 is 4 with a remainder of 478.
Record the quotient 4 as the next digit in the result. 
Result so far: 774.0
The remainder is 478 after subtracting 2588 from 3066.
Append the next digit (1) from the dividend to 478 and continue with: 4781 / 647

Going ahead to step 7:
647 can be fit into 4781 7 times, resulting in a remainder of 252.
Use 7 as the next digit of our solution. 
Result so far: 7747.0
If we take 4529 away from 4781, we end up with 252.
Append the next digit (6) from the dividend to 252 and continue with: 2526 / 647

Going ahead to step 8:
2526 divided by 647 is 3 with a remainder of 585.
The number 3 becomes the next digit in our result. 
Result so far: 77473.0
If we take 1941 away from 2526, we end up with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Step 9:
If we divide 5850 by 647, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 77473.9
Subtract 5823 from 5850 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 10:
The number 647 fits into 270 0 times, leaving a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 77473.9
The remainder is 270 after subtracting 0 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
647 goes into 2700 4 times with a remainder of 112.
Record the quotient 4 as the next digit in the result. 
Result so far: 77473.904
The remainder is 112 after subtracting 2588 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
If we divide 1120 by 647, we get 1 and a remainder of 473.
Use 1 as the next digit of our solution. 
Result so far: 77473.9041
The remainder is 473 after subtracting 647 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Going ahead to step 13:
When dividing 4730 by 647, we get 7 with a remainder of 201.
Write down 7 as next digit of the result. 
Result so far: 77473.90417
If we take 4529 away from 4730, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 14:
2010 divided by 647 is 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 77473.904173
Deduct 1941 from 2010 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 15:
When dividing 690 by 647, we get 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 77473.9041731
If we subtract 647 from 690, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 16:
If we divide 430 by 647, we get 0 and a remainder of 430.
Use 0 as the next digit of our solution. 
Result so far: 77473.9041731
If we subtract 0 from 430, 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.

After the division, we end up with 77473.9041731 and a remainder of 4.3e-07.
