We're dividing 45573 by 19 
We want to divide 45573 by 19.

On to step 1:
4 divided by 19 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 19

On to step 2:
19 goes into 45 2 times with a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 38 from 45 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 19

Step 3:
75 divided by 19 is 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 23.0
If we subtract 57 from 75, we get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 19

Advancing to step 4:
When dividing 187 by 19, we get 9 with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
Subtract 171 from 187 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 19

On to step 5:
163 divided by 19 is 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 2398.0
The remainder is 11 after subtracting 152 from 163.
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 6:
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: 2398.5
The remainder is 15 after subtracting 95 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
When dividing 150 by 19, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 2398.57
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 8:
170 divided by 19 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 2398.578
If we take 152 away from 170, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
When dividing 180 by 19, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 2398.5789
If we subtract 171 from 180, we 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.

Advancing to step 10:
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: 2398.57894
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.

Advancing to step 11:
If we divide 140 by 19, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 2398.578947
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
If we divide 70 by 19, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 2398.5789473
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.

Advancing to step 13:
When dividing 130 by 19, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 2398.57894736
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 2398.57894736, with a leftover of 1.6e-08.
