We look at the division of 545121 by 19 
We want to divide 545121 by 19.

Moving on to step 1:
When dividing 5 by 19, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 19

Going ahead to step 2:
The number 19 fits into 54 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 38 away from 54, we end up with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 19

Advancing to step 3:
165 divided by 19 is 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we take 152 away from 165, we end up with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 19

On to step 4:
131 divided by 19 is 6 with a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 286.0
Subtracting 114 from 131 leaves us with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 19

Moving on to step 5:
If we divide 172 by 19, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 2869.0
Subtracting 171 from 172 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 19

Advancing to step 6:
When dividing 11 by 19, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 28690.0
Subtracting 0 from 11 leaves us 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.

Going ahead to step 7:
If we divide 110 by 19, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 28690.5
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.

Moving on to step 8:
If we divide 150 by 19, we get 7 and a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 28690.57
If we subtract 133 from 150, we 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.

Going ahead to step 9:
170 divided by 19 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 28690.578
If we subtract 152 from 170, we 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:
If we divide 180 by 19, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 28690.5789
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 28690.57894
If we subtract 76 from 90, 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.

Step 12:
19 goes into 140 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 28690.578947
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
When dividing 70 by 19, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 28690.5789473
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
If we divide 130 by 19, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 28690.57894736
Deduct 114 from 130 and we're left with 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 28690.57894736, with a leftover of 1.6e-08.
