We're dividing 19251690 by 380 
We want to figure out the number of times 19251690 can be divided by 380.

Going ahead to step 1:
When dividing 1 by 380, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 380

Going ahead to step 2:
380 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 380

Advancing to step 3:
380 goes into 192 0 times with a remainder of 192.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 192 after subtracting 0 from 192.
Bring next digit (5) of the dividend behind the 192 and repeat the process: 1925 / 380

Step 4:
When dividing 1925 by 380, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 1900 from 1925 leaves us with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 380

On to step 5:
380 can be fit into 251 0 times, resulting in a remainder of 251.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 251 and we're left with 251.
Fetch the next digit (6) from the dividend, attach it to 251 and continue: 2516 / 380

Step 6:
380 goes into 2516 6 times with a remainder of 236.
Use 6 as the next digit of our solution. 
Result so far: 506.0
The remainder is 236 after subtracting 2280 from 2516.
Fetch the next digit (9) from the dividend, attach it to 236 and continue: 2369 / 380

Step 7:
The number 380 fits into 2369 6 times, leaving a remainder of 89.
The number 6 becomes the next digit in our result. 
Result so far: 5066.0
The remainder is 89 after subtracting 2280 from 2369.
Bring next digit (0) of the dividend behind the 89 and repeat the process: 890 / 380

On to step 8:
380 goes into 890 2 times with a remainder of 130.
Record the quotient 2 as the next digit in the result. 
Result so far: 50662.0
If we take 760 away from 890, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 9:
1300 divided by 380 is 3 with a remainder of 160.
Record the quotient 3 as the next digit in the result. 
Result so far: 50662.3
If we subtract 1140 from 1300, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
380 goes into 1600 4 times with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 50662.34
If we subtract 1520 from 1600, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
800 divided by 380 is 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 50662.342
Subtract 760 from 800 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.

On to step 12:
When dividing 400 by 380, we get 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 50662.3421
Subtract 380 from 400 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
The number 380 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 50662.3421
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 14:
If we divide 2000 by 380, we get 5 and a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 50662.342105
The remainder is 100 after subtracting 1900 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 15:
When dividing 1000 by 380, we get 2 with a remainder of 240.
The next digit of our result is 2. 
Result so far: 50662.3421052
If we take 760 away from 1000, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 16:
2400 divided by 380 is 6 with a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 50662.34210526
If we subtract 2280 from 2400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 50662.34210526, with a leftover of 1.2e-07.
