838543 ÷ 77 
We're looking to find how many times 77 goes into 838543.

Moving on to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 77

Moving on to step 2:
83 divided by 77 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 77 from 83 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 77

Let's proceed to step 3:
77 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 77

Advancing to step 4:
When dividing 685 by 77, we get 8 with a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtracting 616 from 685 leaves us with 69.
Include the next digit (4) from the dividend after 69, then repeat: 694 / 77

On to step 5:
The number 77 fits into 694 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 1089.0
If we take 693 away from 694, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 77

Step 6:
77 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 10890.0
Subtract 0 from 13 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
If we divide 130 by 77, we get 1 and a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 10890.1
The remainder is 53 after subtracting 77 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 8:
77 goes into 530 6 times with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 10890.16
The remainder is 68 after subtracting 462 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
77 can be fit into 680 8 times, resulting in a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 10890.168
The remainder is 64 after subtracting 616 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
77 can be fit into 640 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 10890.1688
Subtract 616 from 640 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 10890.1688 with a remaining 0.00024.
