180639 ÷ 19 
We want to figure out the number of times 180639 can be divided by 19.

Let's proceed to step 1:
The number 19 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 19

On to step 2:
19 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 19

Advancing to step 3:
180 divided by 19 is 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 9 after subtracting 171 from 180.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 19

Advancing to step 4:
19 can be fit into 96 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
If we subtract 95 from 96, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 19

Advancing to step 5:
If we divide 13 by 19, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 950.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 19

Going ahead to step 6:
19 can be fit into 139 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 9507.0
If we take 133 away from 139, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 19 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 9507.3
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
19 goes into 30 1 times with a remainder of 11.
The next digit of our result is 1. 
Result so far: 9507.31
If we take 19 away from 30, 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.

Step 9:
The number 19 fits into 110 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 9507.315
Subtracting 95 from 110 leaves us with 15.
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 10:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 9507.3157
If we take 133 away from 150, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 9507.31578
Deduct 152 from 170 and we're left 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.

Advancing to step 12:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 9507.315789
Deduct 171 from 180 and we're left 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.

Let's proceed to step 13:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 9507.3157894
Deduct 76 from 90 and we're left with 14.
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 14:
19 goes into 140 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 9507.31578947
Subtract 133 from 140 to 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.

The final outcome is 9507.31578947, with a leftover of 7e-09.
