We're dividing 50429421 by 647 
Let's see how many times 647 fits into 50429421.

Going ahead to step 1:
The number 647 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 647

Moving on to step 2:
647 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 647

On to step 3:
The number 647 fits into 504 0 times, leaving a remainder of 504.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 504 and we're left with 504.
Grab the next digit (2) from the dividend, add it to 504, then carry on: 5042 / 647

Let's proceed to step 4:
The number 647 fits into 5042 7 times, leaving a remainder of 513.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 4529 from 5042 and we're left with 513.
Include the next digit (9) from the dividend after 513, then repeat: 5139 / 647

Advancing to step 5:
5139 divided by 647 is 7 with a remainder of 610.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtract 4529 from 5139 to get 610.
Grab the next digit (4) from the dividend, add it to 610, then carry on: 6104 / 647

Let's proceed to step 6:
If we divide 6104 by 647, we get 9 and a remainder of 281.
The number 9 becomes the next digit in our result. 
Result so far: 779.0
The remainder is 281 after subtracting 5823 from 6104.
Bring next digit (2) of the dividend behind the 281 and repeat the process: 2812 / 647

Going ahead to step 7:
647 goes into 2812 4 times with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 7794.0
The remainder is 224 after subtracting 2588 from 2812.
Fetch the next digit (1) from the dividend, attach it to 224 and continue: 2241 / 647

On to step 8:
When dividing 2241 by 647, we get 3 with a remainder of 300.
The next digit of our result is 3. 
Result so far: 77943.0
If we take 1941 away from 2241, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 9:
3000 divided by 647 is 4 with a remainder of 412.
Put 4 as the next digit of the answer. 
Result so far: 77943.4
If we subtract 2588 from 3000, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 10:
4120 divided by 647 is 6 with a remainder of 238.
The next digit of our result is 6. 
Result so far: 77943.46
The remainder is 238 after subtracting 3882 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 11:
When dividing 2380 by 647, we get 3 with a remainder of 439.
Write down 3 as next digit of the result. 
Result so far: 77943.463
If we subtract 1941 from 2380, we get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 12:
The number 647 fits into 4390 6 times, leaving a remainder of 508.
Put 6 as the next digit of the answer. 
Result so far: 77943.4636
Subtract 3882 from 4390 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 13:
5080 divided by 647 is 7 with a remainder of 551.
Put 7 as the next digit of the answer. 
Result so far: 77943.46367
Subtracting 4529 from 5080 leaves us with 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Let's proceed to step 14:
647 goes into 5510 8 times with a remainder of 334.
The number 8 becomes the next digit in our result. 
Result so far: 77943.463678
Subtracting 5176 from 5510 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 15:
The number 647 fits into 3340 5 times, leaving a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 77943.4636785
Subtract 3235 from 3340 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 16:
The number 647 fits into 1050 1 times, leaving a remainder of 403.
The number 1 becomes the next digit in our result. 
Result so far: 77943.46367851
Deduct 647 from 1050 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

The final outcome is 77943.46367851, with a leftover of 4.03e-07.
