We're dividing 54915966 by 685 
Let's see how many times 685 fits into 54915966.

Let's proceed to step 1:
When dividing 5 by 685, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 685

Going ahead to step 2:
If we divide 54 by 685, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 685

Advancing to step 3:
When dividing 549 by 685, we get 0 with a remainder of 549.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 549 leaves us with 549.
Grab the next digit (1) from the dividend, add it to 549, then carry on: 5491 / 685

Moving on to step 4:
685 can be fit into 5491 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 5480 from 5491 to get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 685

Step 5:
685 can be fit into 115 0 times, resulting in a remainder of 115.
The next digit of our result is 0. 
Result so far: 80.0
Subtract 0 from 115 to get 115.
Fetch the next digit (9) from the dividend, attach it to 115 and continue: 1159 / 685

Moving on to step 6:
If we divide 1159 by 685, we get 1 and a remainder of 474.
Write down 1 as next digit of the result. 
Result so far: 801.0
If we subtract 685 from 1159, we get 474.
Append the next digit (6) from the dividend to 474 and continue with: 4746 / 685

On to step 7:
If we divide 4746 by 685, we get 6 and a remainder of 636.
Use 6 as the next digit of our solution. 
Result so far: 8016.0
Subtract 4110 from 4746 to get 636.
Take the next digit (6) from the dividend and append it to 636, then repeat: 6366 / 685

Step 8:
If we divide 6366 by 685, we get 9 and a remainder of 201.
Use 9 as the next digit of our solution. 
Result so far: 80169.0
If we take 6165 away from 6366, 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.

Advancing to step 9:
685 goes into 2010 2 times with a remainder of 640.
Use 2 as the next digit of our solution. 
Result so far: 80169.2
Deduct 1370 from 2010 and we're left 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.

Going ahead to step 10:
If we divide 6400 by 685, we get 9 and a remainder of 235.
Put 9 as the next digit of the answer. 
Result so far: 80169.29
The remainder is 235 after subtracting 6165 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 11:
685 goes into 2350 3 times with a remainder of 295.
Write down 3 as next digit of the result. 
Result so far: 80169.293
Subtracting 2055 from 2350 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 12:
685 goes into 2950 4 times with a remainder of 210.
Write down 4 as next digit of the result. 
Result so far: 80169.2934
The remainder is 210 after subtracting 2740 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 13:
When dividing 2100 by 685, we get 3 with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 80169.29343
Subtracting 2055 from 2100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 14:
685 goes into 450 0 times with a remainder of 450.
The next digit of our result is 0. 
Result so far: 80169.29343
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 15:
If we divide 4500 by 685, we get 6 and a remainder of 390.
The next digit of our result is 6. 
Result so far: 80169.2934306
Subtract 4110 from 4500 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 16:
685 can be fit into 3900 5 times, resulting in a remainder of 475.
The number 5 becomes the next digit in our result. 
Result so far: 80169.29343065
Subtracting 3425 from 3900 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

In conclusion, the division gives 80169.29343065 with a balance of 4.75e-07.
