We look at the division of 21069588 by 103 
Our goal is to divide 21069588 by 103.

Going ahead to step 1:
The number 103 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 103

Step 2:
If we divide 21 by 103, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 103

Let's proceed to step 3:
The number 103 fits into 210 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we take 206 away from 210, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 103

Let's proceed to step 4:
If we divide 46 by 103, we get 0 and a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 46, we get 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 103

On to step 5:
103 goes into 469 4 times with a remainder of 57.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Deduct 412 from 469 and we're left with 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 103

Let's proceed to step 6:
The number 103 fits into 575 5 times, leaving a remainder of 60.
The next digit of our result is 5. 
Result so far: 2045.0
If we take 515 away from 575, we end up with 60.
Append the next digit (8) from the dividend to 60 and continue with: 608 / 103

Step 7:
103 goes into 608 5 times with a remainder of 93.
Use 5 as the next digit of our solution. 
Result so far: 20455.0
Subtract 515 from 608 to get 93.
Bring next digit (8) of the dividend behind the 93 and repeat the process: 938 / 103

On to step 8:
The number 103 fits into 938 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 204559.0
The remainder is 11 after subtracting 927 from 938.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
103 can be fit into 110 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 204559.1
If we take 103 away from 110, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
If we divide 70 by 103, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 204559.1
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
The number 103 fits into 700 6 times, leaving a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 204559.106
If we subtract 618 from 700, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 12:
When dividing 820 by 103, we get 7 with a remainder of 99.
Record the quotient 7 as the next digit in the result. 
Result so far: 204559.1067
Subtract 721 from 820 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 13:
103 goes into 990 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 204559.10679
Subtract 927 from 990 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 14:
The number 103 fits into 630 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 204559.106796
Subtracting 618 from 630 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
When dividing 120 by 103, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 204559.1067961
Subtracting 103 from 120 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 16:
When dividing 170 by 103, we get 1 with a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 204559.10679611
Deduct 103 from 170 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final result is 204559.10679611 with a remainder of 6.7e-08.
