121668 divided by 19 
Our goal is to divide 121668 by 19.

Let's proceed to step 1:
19 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 19

Moving on to step 2:
When dividing 12 by 19, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 19

On to step 3:
If we divide 121 by 19, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 114 from 121, we get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 19

Advancing to step 4:
The number 19 fits into 76 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 76 from 76 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 19

Step 5:
6 divided by 19 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 640.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 19

Let's proceed to step 6:
19 can be fit into 68 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 6403.0
If we take 57 away from 68, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 19 fits into 110 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 6403.5
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 6403.57
Subtract 133 from 150 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
When dividing 170 by 19, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 6403.578
Subtract 152 from 170 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
19 can be fit into 180 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 6403.5789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
90 divided by 19 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 6403.57894
The remainder is 14 after subtracting 76 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
140 divided by 19 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 6403.578947
If we take 133 away from 140, 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.

Moving on to step 13:
If we divide 70 by 19, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 6403.5789473
Deduct 57 from 70 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
When dividing 130 by 19, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 6403.57894736
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 6403.57894736, with a leftover of 1.6e-08.
