Let's divide 16680450 by 122
Let's see how many times 122 fits into 16680450.

Going ahead to step 1:
When dividing 1 by 122, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 122

Going ahead to step 2:
16 divided by 122 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 122

Step 3:
If we divide 166 by 122, we get 1 and a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 44 after subtracting 122 from 166.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 122

Going ahead to step 4:
122 goes into 448 3 times with a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 366 away from 448, we end up with 82.
Bring next digit (0) of the dividend behind the 82 and repeat the process: 820 / 122

Going ahead to step 5:
122 can be fit into 820 6 times, resulting in a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 136.0
If we take 732 away from 820, we end up with 88.
Take the next digit (4) from the dividend and append it to 88, then repeat: 884 / 122

On to step 6:
884 divided by 122 is 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 1367.0
The remainder is 30 after subtracting 854 from 884.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 122

Going ahead to step 7:
122 goes into 305 2 times with a remainder of 61.
Use 2 as the next digit of our solution. 
Result so far: 13672.0
If we subtract 244 from 305, we get 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 122

Advancing to step 8:
If we divide 610 by 122, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 136725.0
Deduct 610 from 610 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
122 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 136725.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
122 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 136725.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 136725.0, with a leftover of 0.0.
