We look at the division of 12228589 by 103 
Let's see how many times 103 fits into 12228589.

Step 1:
1 divided by 103 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 103

Let's proceed to step 2:
12 divided by 103 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 103

Going ahead to step 3:
The number 103 fits into 122 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 103 away from 122, we end up with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 103

Step 4:
192 divided by 103 is 1 with a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 89 after subtracting 103 from 192.
Fetch the next digit (8) from the dividend, attach it to 89 and continue: 898 / 103

On to step 5:
103 can be fit into 898 8 times, resulting in a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Subtracting 824 from 898 leaves us with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 103

Going ahead to step 6:
If we divide 745 by 103, we get 7 and a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 1187.0
Subtracting 721 from 745 leaves us with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 103

Advancing to step 7:
103 goes into 248 2 times with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 11872.0
If we take 206 away from 248, we end up with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 103

On to step 8:
103 goes into 429 4 times with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 118724.0
Subtracting 412 from 429 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.

Going ahead to step 9:
If we divide 170 by 103, we get 1 and a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 118724.1
Subtracting 103 from 170 leaves us 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.

Let's proceed to step 10:
The number 103 fits into 670 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 118724.16
Deduct 618 from 670 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
The number 103 fits into 520 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 118724.165
If we subtract 515 from 520, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
If we divide 50 by 103, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 118724.165
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
103 goes into 500 4 times with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 118724.16504
Subtracting 412 from 500 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 14:
When dividing 880 by 103, we get 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 118724.165048
Subtract 824 from 880 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 15:
If we divide 560 by 103, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 118724.1650485
If we take 515 away from 560, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 16:
103 can be fit into 450 4 times, resulting in a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 118724.16504854
Deduct 412 from 450 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 118724.16504854, with a leftover of 3.8e-08.
