We look at the division of 172490 by 19 
Our goal is to divide 172490 by 19.

Let's proceed to step 1:
19 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
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 19

Let's proceed to step 2:
If we divide 17 by 19, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 19

Advancing to step 3:
When dividing 172 by 19, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 1 after subtracting 171 from 172.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 19

Let's proceed to step 4:
If we divide 14 by 19, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 90.0
Subtract 0 from 14 to get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 19

Moving on to step 5:
19 goes into 149 7 times with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 907.0
The remainder is 16 after subtracting 133 from 149.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 19

Let's proceed to step 6:
When dividing 160 by 19, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 9078.0
If we subtract 152 from 160, we 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.

Moving on to step 7:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 9078.4
Deduct 76 from 80 and we're left 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.

Advancing to step 8:
19 can be fit into 40 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 9078.42
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.

Moving on to step 9:
The number 19 fits into 20 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 9078.421
Deduct 19 from 20 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
When dividing 10 by 19, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 9078.421
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
19 can be fit into 100 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9078.42105
Deduct 95 from 100 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
19 can be fit into 50 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 9078.421052
Deduct 38 from 50 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
19 can be fit into 120 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 9078.4210526
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
If we divide 60 by 19, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 9078.42105263
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 9078.42105263 with a balance of 3e-09.
