Let's divide 55243142 by 686
Let's see how many times 686 fits into 55243142.

Advancing to step 1:
When dividing 5 by 686, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 686

Advancing to step 2:
When dividing 55 by 686, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Take the next digit (2) from the dividend and append it to 55, then repeat: 552 / 686

Step 3:
The number 686 fits into 552 0 times, leaving a remainder of 552.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 552, we get 552.
Bring next digit (4) of the dividend behind the 552 and repeat the process: 5524 / 686

On to step 4:
5524 divided by 686 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 5488 from 5524 to get 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 686

Step 5:
686 can be fit into 363 0 times, resulting in a remainder of 363.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 363 leaves us with 363.
Fetch the next digit (1) from the dividend, attach it to 363 and continue: 3631 / 686

Going ahead to step 6:
The number 686 fits into 3631 5 times, leaving a remainder of 201.
The number 5 becomes the next digit in our result. 
Result so far: 805.0
Subtract 3430 from 3631 to get 201.
Fetch the next digit (4) from the dividend, attach it to 201 and continue: 2014 / 686

Step 7:
686 can be fit into 2014 2 times, resulting in a remainder of 642.
Put 2 as the next digit of the answer. 
Result so far: 8052.0
Subtract 1372 from 2014 to get 642.
Append the next digit (2) from the dividend to 642 and continue with: 6422 / 686

On to step 8:
The number 686 fits into 6422 9 times, leaving a remainder of 248.
Record the quotient 9 as the next digit in the result. 
Result so far: 80529.0
Subtract 6174 from 6422 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 9:
The number 686 fits into 2480 3 times, leaving a remainder of 422.
The next digit of our result is 3. 
Result so far: 80529.3
Subtracting 2058 from 2480 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Advancing to step 10:
If we divide 4220 by 686, we get 6 and a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 80529.36
Deduct 4116 from 4220 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
686 can be fit into 1040 1 times, resulting in a remainder of 354.
The next digit of our result is 1. 
Result so far: 80529.361
Deduct 686 from 1040 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 12:
When dividing 3540 by 686, we get 5 with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 80529.3615
If we take 3430 away from 3540, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
When dividing 1100 by 686, we get 1 with a remainder of 414.
Write down 1 as next digit of the result. 
Result so far: 80529.36151
Subtracting 686 from 1100 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 14:
686 goes into 4140 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 80529.361516
Subtracting 4116 from 4140 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 15:
240 divided by 686 is 0 with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 80529.361516
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 16:
If we divide 2400 by 686, we get 3 and a remainder of 342.
Put 3 as the next digit of the answer. 
Result so far: 80529.36151603
Deduct 2058 from 2400 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

After the division, we end up with 80529.36151603 and a remainder of 3.42e-07.
