Let's divide 51397573 by 492
We want to figure out the number of times 51397573 can be divided by 492.

Moving on to step 1:
The number 492 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 492

Advancing to step 2:
The number 492 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 492

Going ahead to step 3:
492 can be fit into 513 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 492 away from 513, we end up with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 492

Going ahead to step 4:
492 goes into 219 0 times with a remainder of 219.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 219, we end up with 219.
Bring next digit (7) of the dividend behind the 219 and repeat the process: 2197 / 492

Step 5:
If we divide 2197 by 492, we get 4 and a remainder of 229.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Deduct 1968 from 2197 and we're left with 229.
Include the next digit (5) from the dividend after 229, then repeat: 2295 / 492

Advancing to step 6:
If we divide 2295 by 492, we get 4 and a remainder of 327.
Put 4 as the next digit of the answer. 
Result so far: 1044.0
Deduct 1968 from 2295 and we're left with 327.
Grab the next digit (7) from the dividend, add it to 327, then carry on: 3277 / 492

Step 7:
492 goes into 3277 6 times with a remainder of 325.
The next digit of our result is 6. 
Result so far: 10446.0
If we take 2952 away from 3277, we end up with 325.
Append the next digit (3) from the dividend to 325 and continue with: 3253 / 492

Let's proceed to step 8:
If we divide 3253 by 492, we get 6 and a remainder of 301.
Use 6 as the next digit of our solution. 
Result so far: 104466.0
Deduct 2952 from 3253 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 9:
When dividing 3010 by 492, we get 6 with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 104466.6
If we take 2952 away from 3010, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
492 can be fit into 580 1 times, resulting in a remainder of 88.
The number 1 becomes the next digit in our result. 
Result so far: 104466.61
If we subtract 492 from 580, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
If we divide 880 by 492, we get 1 and a remainder of 388.
Put 1 as the next digit of the answer. 
Result so far: 104466.611
Subtracting 492 from 880 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

The final result is 104466.611 with a remainder of 0.0388.
