We look at the division of 53138543 by 490 
We want to figure out the number of times 53138543 can be divided by 490.

On to step 1:
490 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 490

Moving on to step 2:
If we divide 53 by 490, we get 0 and a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 490

Moving on to step 3:
The number 490 fits into 531 1 times, leaving a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 490 from 531 to get 41.
Fetch the next digit (3) from the dividend, attach it to 41 and continue: 413 / 490

On to step 4:
If we divide 413 by 490, we get 0 and a remainder of 413.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 413 after subtracting 0 from 413.
Fetch the next digit (8) from the dividend, attach it to 413 and continue: 4138 / 490

Step 5:
When dividing 4138 by 490, we get 8 with a remainder of 218.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we take 3920 away from 4138, we end up with 218.
Take the next digit (5) from the dividend and append it to 218, then repeat: 2185 / 490

Going ahead to step 6:
When dividing 2185 by 490, we get 4 with a remainder of 225.
Record the quotient 4 as the next digit in the result. 
Result so far: 1084.0
If we subtract 1960 from 2185, we get 225.
Take the next digit (4) from the dividend and append it to 225, then repeat: 2254 / 490

On to step 7:
490 can be fit into 2254 4 times, resulting in a remainder of 294.
Use 4 as the next digit of our solution. 
Result so far: 10844.0
Deduct 1960 from 2254 and we're left with 294.
Append the next digit (3) from the dividend to 294 and continue with: 2943 / 490

Going ahead to step 8:
2943 divided by 490 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 108446.0
If we take 2940 away from 2943, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
490 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 108446.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 490, we get 0 and a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 108446.0
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 108446.0 and a remainder of 0.3.
