Let's divide 84380378 by 492
Let's see how many times 492 fits into 84380378.

Advancing to step 1:
492 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 take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 492

On to step 2:
84 divided by 492 is 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Fetch the next digit (3) from the dividend, attach it to 84 and continue: 843 / 492

Moving on to step 3:
The number 492 fits into 843 1 times, leaving a remainder of 351.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 492 from 843, we get 351.
Include the next digit (8) from the dividend after 351, then repeat: 3518 / 492

Going ahead to step 4:
3518 divided by 492 is 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 3444 away from 3518, we end up with 74.
Take the next digit (0) from the dividend and append it to 74, then repeat: 740 / 492

Moving on to step 5:
When dividing 740 by 492, we get 1 with a remainder of 248.
Use 1 as the next digit of our solution. 
Result so far: 171.0
Subtract 492 from 740 to get 248.
Include the next digit (3) from the dividend after 248, then repeat: 2483 / 492

Let's proceed to step 6:
2483 divided by 492 is 5 with a remainder of 23.
The next digit of our result is 5. 
Result so far: 1715.0
The remainder is 23 after subtracting 2460 from 2483.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 492

Step 7:
When dividing 237 by 492, we get 0 with a remainder of 237.
Write down 0 as next digit of the result. 
Result so far: 17150.0
Deduct 0 from 237 and we're left with 237.
Fetch the next digit (8) from the dividend, attach it to 237 and continue: 2378 / 492

Advancing to step 8:
492 goes into 2378 4 times with a remainder of 410.
Put 4 as the next digit of the answer. 
Result so far: 171504.0
If we subtract 1968 from 2378, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 9:
492 can be fit into 4100 8 times, resulting in a remainder of 164.
Write down 8 as next digit of the result. 
Result so far: 171504.8
Subtract 3936 from 4100 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
If we divide 1640 by 492, we get 3 and a remainder of 164.
Use 3 as the next digit of our solution. 
Result so far: 171504.83
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.

On to step 11:
When dividing 1640 by 492, we get 3 with a remainder of 164.
The number 3 becomes the next digit in our result. 
Result so far: 171504.833
Deduct 1476 from 1640 and we're left 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.

The final result is 171504.833 with a remainder of 0.0164.
