We're dividing 53199089 by 103 
We want to figure out the number of times 53199089 can be divided by 103.

Going ahead to step 1:
103 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 103

Let's proceed to step 2:
103 goes into 53 0 times with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 103

On to step 3:
103 can be fit into 531 5 times, resulting in a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 515 away from 531, we end up with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 103

On to step 4:
103 goes into 169 1 times with a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 66 after subtracting 103 from 169.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 103

Moving on to step 5:
If we divide 669 by 103, we get 6 and a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 516.0
Subtracting 618 from 669 leaves us with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 103

On to step 6:
When dividing 510 by 103, we get 4 with a remainder of 98.
Use 4 as the next digit of our solution. 
Result so far: 5164.0
If we take 412 away from 510, we end up with 98.
Fetch the next digit (8) from the dividend, attach it to 98 and continue: 988 / 103

Moving on to step 7:
The number 103 fits into 988 9 times, leaving a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 51649.0
Deduct 927 from 988 and we're left with 61.
Append the next digit (9) from the dividend to 61 and continue with: 619 / 103

Advancing to step 8:
When dividing 619 by 103, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 516496.0
Subtracting 618 from 619 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
The number 103 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 516496.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
103 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 516496.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 516496.0 and a remainder of 0.1.
