199955 ÷ 19 
Our goal is to divide 199955 by 19.

On to step 1:
The number 19 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 19

On to step 2:
When dividing 19 by 19, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 19 from 19 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 19

Step 3:
When dividing 9 by 19, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 9 to get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 19

Going ahead to step 4:
The number 19 fits into 99 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Deduct 95 from 99 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 19

On to step 5:
The number 19 fits into 45 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 1052.0
If we take 38 away from 45, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 19

Going ahead to step 6:
If we divide 75 by 19, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 10523.0
Deduct 57 from 75 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.

Going ahead to step 7:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 10523.9
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 8:
If we divide 90 by 19, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 10523.94
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.

Going ahead to step 9:
If we divide 140 by 19, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 10523.947
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.

On to step 10:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 10523.9473
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
19 can be fit into 130 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 10523.94736
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.

Moving on to step 12:
19 goes into 160 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 10523.947368
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
19 goes into 80 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 10523.9473684
If we take 76 away from 80, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
40 divided by 19 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 10523.94736842
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 10523.94736842 with a remaining 2e-09.
