Let's divide 19993189 by 180
We want to divide 19993189 by 180.

On to step 1:
180 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 180

Advancing to step 2:
When dividing 19 by 180, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 180

Step 3:
180 goes into 199 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 180 from 199 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 180

Going ahead to step 4:
199 divided by 180 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 180 from 199 to get 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 180

On to step 5:
180 goes into 193 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 111.0
If we subtract 180 from 193, we get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 180

On to step 6:
180 goes into 131 0 times with a remainder of 131.
Write down 0 as next digit of the result. 
Result so far: 1110.0
The remainder is 131 after subtracting 0 from 131.
Grab the next digit (8) from the dividend, add it to 131, then carry on: 1318 / 180

Advancing to step 7:
If we divide 1318 by 180, we get 7 and a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 11107.0
If we take 1260 away from 1318, we end up with 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 180

Step 8:
180 can be fit into 589 3 times, resulting in a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 111073.0
Subtracting 540 from 589 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
180 goes into 490 2 times with a remainder of 130.
Record the quotient 2 as the next digit in the result. 
Result so far: 111073.2
If we subtract 360 from 490, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
The number 180 fits into 1300 7 times, leaving a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 111073.27
Subtract 1260 from 1300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
180 can be fit into 400 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 111073.272
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
If we divide 400 by 180, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 111073.2722
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 111073.2722 with a remainder of 0.0004.
