We divide 77378039 by 115
We want to figure out the number of times 77378039 can be divided by 115.

On to step 1:
When dividing 7 by 115, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 115

Moving on to step 2:
77 divided by 115 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 115

Moving on to step 3:
773 divided by 115 is 6 with a remainder of 83.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 83 after subtracting 690 from 773.
Include the next digit (7) from the dividend after 83, then repeat: 837 / 115

Step 4:
If we divide 837 by 115, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 67.0
The remainder is 32 after subtracting 805 from 837.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 115

Advancing to step 5:
When dividing 328 by 115, we get 2 with a remainder of 98.
Put 2 as the next digit of the answer. 
Result so far: 672.0
Subtracting 230 from 328 leaves us with 98.
Take the next digit (0) from the dividend and append it to 98, then repeat: 980 / 115

Advancing to step 6:
115 can be fit into 980 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 6728.0
The remainder is 60 after subtracting 920 from 980.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 115

Step 7:
115 can be fit into 603 5 times, resulting in a remainder of 28.
The next digit of our result is 5. 
Result so far: 67285.0
If we take 575 away from 603, we end up with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 115

Moving on to step 8:
289 divided by 115 is 2 with a remainder of 59.
The next digit of our result is 2. 
Result so far: 672852.0
Subtracting 230 from 289 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
When dividing 590 by 115, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 672852.5
The remainder is 15 after subtracting 575 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
The number 115 fits into 150 1 times, leaving a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 672852.51
The remainder is 35 after subtracting 115 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
When dividing 350 by 115, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 672852.513
Deduct 345 from 350 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
115 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 672852.513
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
When dividing 500 by 115, we get 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 672852.51304
If we take 460 away from 500, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
115 can be fit into 400 3 times, resulting in a remainder of 55.
The next digit of our result is 3. 
Result so far: 672852.513043
If we take 345 away from 400, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 15:
115 can be fit into 550 4 times, resulting in a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 672852.5130434
The remainder is 90 after subtracting 460 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 16:
115 can be fit into 900 7 times, resulting in a remainder of 95.
The next digit of our result is 7. 
Result so far: 672852.51304347
The remainder is 95 after subtracting 805 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

In conclusion, the division gives 672852.51304347 with a balance of 9.5e-08.
