Let's divide 1902622 by 399
Our goal is to divide 1902622 by 399.

Step 1:
399 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 399

On to step 2:
If we divide 19 by 399, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 399

Advancing to step 3:
The number 399 fits into 190 0 times, leaving a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 190 leaves us with 190.
Fetch the next digit (2) from the dividend, attach it to 190 and continue: 1902 / 399

Going ahead to step 4:
399 goes into 1902 4 times with a remainder of 306.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 1596 from 1902, we get 306.
Include the next digit (6) from the dividend after 306, then repeat: 3066 / 399

Step 5:
399 can be fit into 3066 7 times, resulting in a remainder of 273.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we subtract 2793 from 3066, we get 273.
Append the next digit (2) from the dividend to 273 and continue with: 2732 / 399

On to step 6:
When dividing 2732 by 399, we get 6 with a remainder of 338.
The next digit of our result is 6. 
Result so far: 476.0
Deduct 2394 from 2732 and we're left with 338.
Append the next digit (2) from the dividend to 338 and continue with: 3382 / 399

Let's proceed to step 7:
The number 399 fits into 3382 8 times, leaving a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 4768.0
If we take 3192 away from 3382, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 8:
When dividing 1900 by 399, we get 4 with a remainder of 304.
Put 4 as the next digit of the answer. 
Result so far: 4768.4
The remainder is 304 after subtracting 1596 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 9:
399 goes into 3040 7 times with a remainder of 247.
Put 7 as the next digit of the answer. 
Result so far: 4768.47
The remainder is 247 after subtracting 2793 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 10:
399 goes into 2470 6 times with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 4768.476
If we subtract 2394 from 2470, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
The number 399 fits into 760 1 times, leaving a remainder of 361.
Use 1 as the next digit of our solution. 
Result so far: 4768.4761
If we subtract 399 from 760, we get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Moving on to step 12:
399 goes into 3610 9 times with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 4768.47619
Subtracting 3591 from 3610 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
190 divided by 399 is 0 with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 4768.47619
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 14:
When dividing 1900 by 399, we get 4 with a remainder of 304.
Put 4 as the next digit of the answer. 
Result so far: 4768.4761904
Deduct 1596 from 1900 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 15:
399 goes into 3040 7 times with a remainder of 247.
Use 7 as the next digit of our solution. 
Result so far: 4768.47619047
Deduct 2793 from 3040 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

In conclusion, the division gives 4768.47619047 with a balance of 2.47e-07.
