We're dividing 78176139 by 209 
We want to divide 78176139 by 209.

Going ahead to step 1:
If we divide 7 by 209, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 209

Going ahead to step 2:
If we divide 78 by 209, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 209

Advancing to step 3:
209 can be fit into 781 3 times, resulting in a remainder of 154.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 627 from 781 to get 154.
Grab the next digit (7) from the dividend, add it to 154, then carry on: 1547 / 209

Going ahead to step 4:
1547 divided by 209 is 7 with a remainder of 84.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 1463 from 1547 leaves us with 84.
Include the next digit (6) from the dividend after 84, then repeat: 846 / 209

Let's proceed to step 5:
846 divided by 209 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
Deduct 836 from 846 and we're left with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 209

Advancing to step 6:
The number 209 fits into 101 0 times, leaving a remainder of 101.
Write down 0 as next digit of the result. 
Result so far: 3740.0
Deduct 0 from 101 and we're left with 101.
Fetch the next digit (3) from the dividend, attach it to 101 and continue: 1013 / 209

Step 7:
If we divide 1013 by 209, we get 4 and a remainder of 177.
The number 4 becomes the next digit in our result. 
Result so far: 37404.0
Subtract 836 from 1013 to get 177.
Bring next digit (9) of the dividend behind the 177 and repeat the process: 1779 / 209

Let's proceed to step 8:
209 goes into 1779 8 times with a remainder of 107.
The number 8 becomes the next digit in our result. 
Result so far: 374048.0
Deduct 1672 from 1779 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 9:
If we divide 1070 by 209, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 374048.5
Subtracting 1045 from 1070 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
209 goes into 250 1 times with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 374048.51
The remainder is 41 after subtracting 209 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 11:
209 can be fit into 410 1 times, resulting in a remainder of 201.
The next digit of our result is 1. 
Result so far: 374048.511
The remainder is 201 after subtracting 209 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

In conclusion, the division gives 374048.511 with a balance of 0.0201.
