We divide 49940864 by 686
We want to figure out the number of times 49940864 can be divided by 686.

Step 1:
4 divided by 686 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 686

Moving on to step 2:
When dividing 49 by 686, we get 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 686

Advancing to step 3:
When dividing 499 by 686, we get 0 with a remainder of 499.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 499 leaves us with 499.
Take the next digit (4) from the dividend and append it to 499, then repeat: 4994 / 686

On to step 4:
686 can be fit into 4994 7 times, resulting in a remainder of 192.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 4802 from 4994 to get 192.
Fetch the next digit (0) from the dividend, attach it to 192 and continue: 1920 / 686

On to step 5:
686 can be fit into 1920 2 times, resulting in a remainder of 548.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 1372 from 1920, we get 548.
Include the next digit (8) from the dividend after 548, then repeat: 5488 / 686

Going ahead to step 6:
When dividing 5488 by 686, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 728.0
Subtract 5488 from 5488 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 686

Going ahead to step 7:
The number 686 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 7280.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 686

On to step 8:
686 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 72800.0
The remainder is 64 after subtracting 0 from 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
686 goes into 640 0 times with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 72800.0
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 10:
When dividing 6400 by 686, we get 9 with a remainder of 226.
Put 9 as the next digit of the answer. 
Result so far: 72800.09
Subtracting 6174 from 6400 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 11:
686 can be fit into 2260 3 times, resulting in a remainder of 202.
Write down 3 as next digit of the result. 
Result so far: 72800.093
If we take 2058 away from 2260, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 12:
When dividing 2020 by 686, we get 2 with a remainder of 648.
Record the quotient 2 as the next digit in the result. 
Result so far: 72800.0932
The remainder is 648 after subtracting 1372 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Moving on to step 13:
686 can be fit into 6480 9 times, resulting in a remainder of 306.
The next digit of our result is 9. 
Result so far: 72800.09329
Subtract 6174 from 6480 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 14:
When dividing 3060 by 686, we get 4 with a remainder of 316.
Put 4 as the next digit of the answer. 
Result so far: 72800.093294
Subtracting 2744 from 3060 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 15:
When dividing 3160 by 686, we get 4 with a remainder of 416.
The number 4 becomes the next digit in our result. 
Result so far: 72800.0932944
Subtract 2744 from 3160 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The final outcome is 72800.0932944, with a leftover of 4.16e-06.
