91567651 divided by 678 
Let's see how many times 678 fits into 91567651.

Going ahead to step 1:
If we divide 9 by 678, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 678

Advancing to step 2:
If we divide 91 by 678, we get 0 and a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Include the next digit (5) from the dividend after 91, then repeat: 915 / 678

Going ahead to step 3:
678 goes into 915 1 times with a remainder of 237.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 678 from 915 to get 237.
Append the next digit (6) from the dividend to 237 and continue with: 2376 / 678

On to step 4:
2376 divided by 678 is 3 with a remainder of 342.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 2034 from 2376, we get 342.
Bring next digit (7) of the dividend behind the 342 and repeat the process: 3427 / 678

On to step 5:
If we divide 3427 by 678, we get 5 and a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Subtract 3390 from 3427 to get 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 678

On to step 6:
678 can be fit into 376 0 times, resulting in a remainder of 376.
The next digit of our result is 0. 
Result so far: 1350.0
Subtract 0 from 376 to get 376.
Include the next digit (5) from the dividend after 376, then repeat: 3765 / 678

Going ahead to step 7:
678 can be fit into 3765 5 times, resulting in a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 13505.0
If we subtract 3390 from 3765, we get 375.
Fetch the next digit (1) from the dividend, attach it to 375 and continue: 3751 / 678

Step 8:
The number 678 fits into 3751 5 times, leaving a remainder of 361.
Put 5 as the next digit of the answer. 
Result so far: 135055.0
Deduct 3390 from 3751 and we're left with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 9:
When dividing 3610 by 678, we get 5 with a remainder of 220.
Put 5 as the next digit of the answer. 
Result so far: 135055.5
Deduct 3390 from 3610 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 10:
2200 divided by 678 is 3 with a remainder of 166.
The next digit of our result is 3. 
Result so far: 135055.53
The remainder is 166 after subtracting 2034 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 11:
When dividing 1660 by 678, we get 2 with a remainder of 304.
The next digit of our result is 2. 
Result so far: 135055.532
Deduct 1356 from 1660 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 12:
678 can be fit into 3040 4 times, resulting in a remainder of 328.
The next digit of our result is 4. 
Result so far: 135055.5324
Subtract 2712 from 3040 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 13:
The number 678 fits into 3280 4 times, leaving a remainder of 568.
Use 4 as the next digit of our solution. 
Result so far: 135055.53244
If we subtract 2712 from 3280, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

The final result is 135055.53244 with a remainder of 0.000568.
