Let's divide 54851946 by 686
We want to divide 54851946 by 686.

Moving on to step 1:
5 divided by 686 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 686

On to step 2:
When dividing 54 by 686, we get 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 686

On to step 3:
548 divided by 686 is 0 with a remainder of 548.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 548, we get 548.
Grab the next digit (5) from the dividend, add it to 548, then carry on: 5485 / 686

Let's proceed to step 4:
The number 686 fits into 5485 7 times, leaving a remainder of 683.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 4802 from 5485 to get 683.
Bring next digit (1) of the dividend behind the 683 and repeat the process: 6831 / 686

Let's proceed to step 5:
The number 686 fits into 6831 9 times, leaving a remainder of 657.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 657 after subtracting 6174 from 6831.
Include the next digit (9) from the dividend after 657, then repeat: 6579 / 686

Advancing to step 6:
6579 divided by 686 is 9 with a remainder of 405.
Write down 9 as next digit of the result. 
Result so far: 799.0
Subtract 6174 from 6579 to get 405.
Grab the next digit (4) from the dividend, add it to 405, then carry on: 4054 / 686

On to step 7:
686 goes into 4054 5 times with a remainder of 624.
Write down 5 as next digit of the result. 
Result so far: 7995.0
If we take 3430 away from 4054, we end up with 624.
Include the next digit (6) from the dividend after 624, then repeat: 6246 / 686

On to step 8:
If we divide 6246 by 686, we get 9 and a remainder of 72.
The next digit of our result is 9. 
Result so far: 79959.0
Subtracting 6174 from 6246 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
When dividing 720 by 686, we get 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 79959.1
If we take 686 away from 720, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
686 can be fit into 340 0 times, resulting in a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 79959.1
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 11:
3400 divided by 686 is 4 with a remainder of 656.
Use 4 as the next digit of our solution. 
Result so far: 79959.104
If we take 2744 away from 3400, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 12:
686 can be fit into 6560 9 times, resulting in a remainder of 386.
Write down 9 as next digit of the result. 
Result so far: 79959.1049
If we take 6174 away from 6560, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 13:
If we divide 3860 by 686, we get 5 and a remainder of 430.
The number 5 becomes the next digit in our result. 
Result so far: 79959.10495
The remainder is 430 after subtracting 3430 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 14:
686 goes into 4300 6 times with a remainder of 184.
The next digit of our result is 6. 
Result so far: 79959.104956
If we subtract 4116 from 4300, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 15:
686 goes into 1840 2 times with a remainder of 468.
The number 2 becomes the next digit in our result. 
Result so far: 79959.1049562
Subtract 1372 from 1840 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 16:
The number 686 fits into 4680 6 times, leaving a remainder of 564.
Use 6 as the next digit of our solution. 
Result so far: 79959.10495626
Subtract 4116 from 4680 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Our division results in 79959.10495626 with a remaining 5.64e-07.
