We're dividing 78642223 by 874 
Our goal is to divide 78642223 by 874.

Step 1:
When dividing 7 by 874, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 874

Let's proceed to step 2:
874 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 874

Moving on to step 3:
If we divide 786 by 874, we get 0 and a remainder of 786.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 786 and we're left with 786.
Bring next digit (4) of the dividend behind the 786 and repeat the process: 7864 / 874

Advancing to step 4:
If we divide 7864 by 874, we get 8 and a remainder of 872.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 6992 from 7864 leaves us with 872.
Include the next digit (2) from the dividend after 872, then repeat: 8722 / 874

Moving on to step 5:
8722 divided by 874 is 9 with a remainder of 856.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we subtract 7866 from 8722, we get 856.
Include the next digit (2) from the dividend after 856, then repeat: 8562 / 874

Let's proceed to step 6:
The number 874 fits into 8562 9 times, leaving a remainder of 696.
Write down 9 as next digit of the result. 
Result so far: 899.0
Deduct 7866 from 8562 and we're left with 696.
Grab the next digit (2) from the dividend, add it to 696, then carry on: 6962 / 874

Going ahead to step 7:
6962 divided by 874 is 7 with a remainder of 844.
The number 7 becomes the next digit in our result. 
Result so far: 8997.0
Deduct 6118 from 6962 and we're left with 844.
Fetch the next digit (3) from the dividend, attach it to 844 and continue: 8443 / 874

Let's proceed to step 8:
If we divide 8443 by 874, we get 9 and a remainder of 577.
Write down 9 as next digit of the result. 
Result so far: 89979.0
Deduct 7866 from 8443 and we're left with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Let's proceed to step 9:
The number 874 fits into 5770 6 times, leaving a remainder of 526.
Write down 6 as next digit of the result. 
Result so far: 89979.6
If we take 5244 away from 5770, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 10:
If we divide 5260 by 874, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 89979.66
The remainder is 16 after subtracting 5244 from 5260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 89979.66, and the remainder is 0.016.
