We look at the division of 18170400 by 77 
Our goal is to divide 18170400 by 77.

Going ahead to step 1:
1 divided by 77 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 77

Going ahead to step 2:
18 divided by 77 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 77

On to step 3:
77 goes into 181 2 times with a remainder of 27.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 154 from 181 to get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 77

Advancing to step 4:
The number 77 fits into 277 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 231 from 277 and we're left with 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 77

Let's proceed to step 5:
77 can be fit into 460 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 235.0
Deduct 385 from 460 and we're left with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 77

Advancing to step 6:
754 divided by 77 is 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 2359.0
If we take 693 away from 754, we end up with 61.
Fetch the next digit (0) from the dividend, attach it to 61 and continue: 610 / 77

Let's proceed to step 7:
77 goes into 610 7 times with a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 23597.0
If we subtract 539 from 610, we get 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 77

Let's proceed to step 8:
77 can be fit into 710 9 times, resulting in a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 235979.0
The remainder is 17 after subtracting 693 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
If we divide 170 by 77, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 235979.2
The remainder is 16 after subtracting 154 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
77 can be fit into 160 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 235979.22
Subtracting 154 from 160 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 235979.22 with a remainder of 0.006.
