We look at the division of 64851490 by 842 
Our goal is to divide 64851490 by 842.

Step 1:
842 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 842

Step 2:
64 divided by 842 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (8) from the dividend to 64 and continue with: 648 / 842

Moving on to step 3:
If we divide 648 by 842, we get 0 and a remainder of 648.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 648, we get 648.
Bring next digit (5) of the dividend behind the 648 and repeat the process: 6485 / 842

Let's proceed to step 4:
If we divide 6485 by 842, we get 7 and a remainder of 591.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 5894 away from 6485, we end up with 591.
Include the next digit (1) from the dividend after 591, then repeat: 5911 / 842

Let's proceed to step 5:
When dividing 5911 by 842, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtracting 5894 from 5911 leaves us with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 842

Step 6:
The number 842 fits into 174 0 times, leaving a remainder of 174.
Use 0 as the next digit of our solution. 
Result so far: 770.0
If we subtract 0 from 174, we get 174.
Bring next digit (9) of the dividend behind the 174 and repeat the process: 1749 / 842

Let's proceed to step 7:
1749 divided by 842 is 2 with a remainder of 65.
Record the quotient 2 as the next digit in the result. 
Result so far: 7702.0
Subtract 1684 from 1749 to get 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 842

Step 8:
842 goes into 650 0 times with a remainder of 650.
Put 0 as the next digit of the answer. 
Result so far: 77020.0
If we subtract 0 from 650, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 9:
6500 divided by 842 is 7 with a remainder of 606.
The next digit of our result is 7. 
Result so far: 77020.7
The remainder is 606 after subtracting 5894 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Let's proceed to step 10:
If we divide 6060 by 842, we get 7 and a remainder of 166.
Record the quotient 7 as the next digit in the result. 
Result so far: 77020.77
If we take 5894 away from 6060, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final outcome is 77020.77, with a leftover of 0.166.
