We're dividing 18917017 by 123 
Let's see how many times 123 fits into 18917017.

On to step 1:
123 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 123

On to step 2:
If we divide 18 by 123, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 123

On to step 3:
189 divided by 123 is 1 with a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 66 after subtracting 123 from 189.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 123

Moving on to step 4:
When dividing 661 by 123, we get 5 with a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 615 from 661 leaves us with 46.
Include the next digit (7) from the dividend after 46, then repeat: 467 / 123

Moving on to step 5:
If we divide 467 by 123, we get 3 and a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
Deduct 369 from 467 and we're left with 98.
Bring next digit (0) of the dividend behind the 98 and repeat the process: 980 / 123

Advancing to step 6:
When dividing 980 by 123, we get 7 with a remainder of 119.
Record the quotient 7 as the next digit in the result. 
Result so far: 1537.0
Subtract 861 from 980 to get 119.
Append the next digit (1) from the dividend to 119 and continue with: 1191 / 123

Moving on to step 7:
The number 123 fits into 1191 9 times, leaving a remainder of 84.
Use 9 as the next digit of our solution. 
Result so far: 15379.0
If we take 1107 away from 1191, we end up with 84.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 123

Let's proceed to step 8:
When dividing 847 by 123, we get 6 with a remainder of 109.
Write down 6 as next digit of the result. 
Result so far: 153796.0
Deduct 738 from 847 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 9:
When dividing 1090 by 123, we get 8 with a remainder of 106.
Use 8 as the next digit of our solution. 
Result so far: 153796.8
Deduct 984 from 1090 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
The number 123 fits into 1060 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 153796.88
Subtracting 984 from 1060 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 153796.88, with a leftover of 0.076.
