We're dividing 85249479 by 678 
Let's see how many times 678 fits into 85249479.

Going ahead to step 1:
678 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 678

Moving on to step 2:
The number 678 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (2) from the dividend and append it to 85, then repeat: 852 / 678

On to step 3:
678 goes into 852 1 times with a remainder of 174.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 174 after subtracting 678 from 852.
Bring next digit (4) of the dividend behind the 174 and repeat the process: 1744 / 678

On to step 4:
If we divide 1744 by 678, we get 2 and a remainder of 388.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 388 after subtracting 1356 from 1744.
Append the next digit (9) from the dividend to 388 and continue with: 3889 / 678

Advancing to step 5:
If we divide 3889 by 678, we get 5 and a remainder of 499.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Subtract 3390 from 3889 to get 499.
Bring next digit (4) of the dividend behind the 499 and repeat the process: 4994 / 678

On to step 6:
If we divide 4994 by 678, we get 7 and a remainder of 248.
The number 7 becomes the next digit in our result. 
Result so far: 1257.0
If we take 4746 away from 4994, we end up with 248.
Append the next digit (7) from the dividend to 248 and continue with: 2487 / 678

Advancing to step 7:
678 can be fit into 2487 3 times, resulting in a remainder of 453.
Use 3 as the next digit of our solution. 
Result so far: 12573.0
If we subtract 2034 from 2487, we get 453.
Fetch the next digit (9) from the dividend, attach it to 453 and continue: 4539 / 678

Moving on to step 8:
4539 divided by 678 is 6 with a remainder of 471.
Write down 6 as next digit of the result. 
Result so far: 125736.0
If we subtract 4068 from 4539, we get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Going ahead to step 9:
When dividing 4710 by 678, we get 6 with a remainder of 642.
The next digit of our result is 6. 
Result so far: 125736.6
The remainder is 642 after subtracting 4068 from 4710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Advancing to step 10:
When dividing 6420 by 678, we get 9 with a remainder of 318.
The next digit of our result is 9. 
Result so far: 125736.69
Deduct 6102 from 6420 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 11:
678 can be fit into 3180 4 times, resulting in a remainder of 468.
Write down 4 as next digit of the result. 
Result so far: 125736.694
If we take 2712 away from 3180, we end up with 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 12:
678 goes into 4680 6 times with a remainder of 612.
The number 6 becomes the next digit in our result. 
Result so far: 125736.6946
Subtracting 4068 from 4680 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 13:
6120 divided by 678 is 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 125736.69469
If we take 6102 away from 6120, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
180 divided by 678 is 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 125736.69469
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 15:
When dividing 1800 by 678, we get 2 with a remainder of 444.
Use 2 as the next digit of our solution. 
Result so far: 125736.6946902
The remainder is 444 after subtracting 1356 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 16:
678 goes into 4440 6 times with a remainder of 372.
Write down 6 as next digit of the result. 
Result so far: 125736.69469026
If we take 4068 away from 4440, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

After the division, we end up with 125736.69469026 and a remainder of 3.72e-07.
