9128978 ÷ 492 
Our goal is to divide 9128978 by 492.

Advancing to step 1:
If we divide 9 by 492, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 492

Advancing to step 2:
The number 492 fits into 91 0 times, leaving a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (2) from the dividend and append it to 91, then repeat: 912 / 492

Step 3:
When dividing 912 by 492, we get 1 with a remainder of 420.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 492 from 912 to get 420.
Take the next digit (8) from the dividend and append it to 420, then repeat: 4208 / 492

Let's proceed to step 4:
492 goes into 4208 8 times with a remainder of 272.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 3936 from 4208, we get 272.
Fetch the next digit (9) from the dividend, attach it to 272 and continue: 2729 / 492

Moving on to step 5:
If we divide 2729 by 492, we get 5 and a remainder of 269.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Subtracting 2460 from 2729 leaves us with 269.
Take the next digit (7) from the dividend and append it to 269, then repeat: 2697 / 492

Going ahead to step 6:
492 goes into 2697 5 times with a remainder of 237.
The next digit of our result is 5. 
Result so far: 1855.0
The remainder is 237 after subtracting 2460 from 2697.
Grab the next digit (8) from the dividend, add it to 237, then carry on: 2378 / 492

Moving on to step 7:
492 can be fit into 2378 4 times, resulting in a remainder of 410.
The number 4 becomes the next digit in our result. 
Result so far: 18554.0
If we take 1968 away from 2378, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 8:
If we divide 4100 by 492, we get 8 and a remainder of 164.
Write down 8 as next digit of the result. 
Result so far: 18554.8
If we take 3936 away from 4100, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 9:
492 can be fit into 1640 3 times, resulting in a remainder of 164.
Write down 3 as next digit of the result. 
Result so far: 18554.83
Subtracting 1476 from 1640 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 10:
If we divide 1640 by 492, we get 3 and a remainder of 164.
The number 3 becomes the next digit in our result. 
Result so far: 18554.833
The remainder is 164 after subtracting 1476 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

After the division, we end up with 18554.833 and a remainder of 0.0164.
