We're dividing 73840392 by 388 
We want to figure out the number of times 73840392 can be divided by 388.

On to step 1:
If we divide 7 by 388, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 388

Moving on to step 2:
The number 388 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 388

Moving on to step 3:
The number 388 fits into 738 1 times, leaving a remainder of 350.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 350 after subtracting 388 from 738.
Fetch the next digit (4) from the dividend, attach it to 350 and continue: 3504 / 388

Let's proceed to step 4:
388 can be fit into 3504 9 times, resulting in a remainder of 12.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 3492 from 3504 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 388

Going ahead to step 5:
388 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Deduct 0 from 120 and we're left with 120.
Include the next digit (3) from the dividend after 120, then repeat: 1203 / 388

On to step 6:
1203 divided by 388 is 3 with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 1903.0
Subtract 1164 from 1203 to get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 388

Advancing to step 7:
When dividing 399 by 388, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 19031.0
Deduct 388 from 399 and we're left with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 388

Going ahead to step 8:
If we divide 112 by 388, we get 0 and a remainder of 112.
The next digit of our result is 0. 
Result so far: 190310.0
If we subtract 0 from 112, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 9:
The number 388 fits into 1120 2 times, leaving a remainder of 344.
Put 2 as the next digit of the answer. 
Result so far: 190310.2
Deduct 776 from 1120 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 10:
388 can be fit into 3440 8 times, resulting in a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 190310.28
Subtract 3104 from 3440 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 11:
388 can be fit into 3360 8 times, resulting in a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 190310.288
Deduct 3104 from 3360 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

In conclusion, the division gives 190310.288 with a balance of 0.0256.
