Let's divide 122990 by 18
We want to divide 122990 by 18.

Going ahead to step 1:
18 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 18

Going ahead to step 2:
18 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 18

Step 3:
18 can be fit into 122 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 108 from 122 leaves us with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 18

Moving on to step 4:
18 goes into 149 8 times with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Deduct 144 from 149 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 18

Going ahead to step 5:
When dividing 59 by 18, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 683.0
Deduct 54 from 59 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 18

Step 6:
If we divide 50 by 18, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 6832.0
The remainder is 14 after subtracting 36 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
18 goes into 140 7 times with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 6832.7
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 18 fits into 140 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 6832.77
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 6832.77, with a leftover of 0.014.
