Let's divide 67878851 by 891
Our goal is to divide 67878851 by 891.

Step 1:
If we divide 6 by 891, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 891

Going ahead to step 2:
When dividing 67 by 891, we get 0 with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Bring next digit (8) of the dividend behind the 67 and repeat the process: 678 / 891

Advancing to step 3:
678 divided by 891 is 0 with a remainder of 678.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 678 to get 678.
Take the next digit (7) from the dividend and append it to 678, then repeat: 6787 / 891

On to step 4:
891 can be fit into 6787 7 times, resulting in a remainder of 550.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 6237 from 6787 to get 550.
Bring next digit (8) of the dividend behind the 550 and repeat the process: 5508 / 891

Step 5:
5508 divided by 891 is 6 with a remainder of 162.
The next digit of our result is 6. 
Result so far: 76.0
Deduct 5346 from 5508 and we're left with 162.
Bring next digit (8) of the dividend behind the 162 and repeat the process: 1628 / 891

Advancing to step 6:
891 can be fit into 1628 1 times, resulting in a remainder of 737.
The number 1 becomes the next digit in our result. 
Result so far: 761.0
The remainder is 737 after subtracting 891 from 1628.
Take the next digit (5) from the dividend and append it to 737, then repeat: 7375 / 891

Moving on to step 7:
The number 891 fits into 7375 8 times, leaving a remainder of 247.
The next digit of our result is 8. 
Result so far: 7618.0
If we subtract 7128 from 7375, we get 247.
Grab the next digit (1) from the dividend, add it to 247, then carry on: 2471 / 891

On to step 8:
The number 891 fits into 2471 2 times, leaving a remainder of 689.
The next digit of our result is 2. 
Result so far: 76182.0
If we subtract 1782 from 2471, we get 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Step 9:
891 goes into 6890 7 times with a remainder of 653.
Write down 7 as next digit of the result. 
Result so far: 76182.7
Subtracting 6237 from 6890 leaves us with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

On to step 10:
The number 891 fits into 6530 7 times, leaving a remainder of 293.
The next digit of our result is 7. 
Result so far: 76182.77
Subtract 6237 from 6530 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Our division results in 76182.77 with a remaining 0.293.
