15393880 ÷ 997 
Let's see how many times 997 fits into 15393880.

Let's proceed to step 1:
When dividing 1 by 997, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 997

On to step 2:
997 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 997

Let's proceed to step 3:
997 goes into 153 0 times with a remainder of 153.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 153 and we're left with 153.
Grab the next digit (9) from the dividend, add it to 153, then carry on: 1539 / 997

On to step 4:
1539 divided by 997 is 1 with a remainder of 542.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 997 from 1539 and we're left with 542.
Fetch the next digit (3) from the dividend, attach it to 542 and continue: 5423 / 997

Advancing to step 5:
The number 997 fits into 5423 5 times, leaving a remainder of 438.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 4985 from 5423 and we're left with 438.
Grab the next digit (8) from the dividend, add it to 438, then carry on: 4388 / 997

Moving on to step 6:
The number 997 fits into 4388 4 times, leaving a remainder of 400.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
Deduct 3988 from 4388 and we're left with 400.
Fetch the next digit (8) from the dividend, attach it to 400 and continue: 4008 / 997

Let's proceed to step 7:
The number 997 fits into 4008 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 1544.0
The remainder is 20 after subtracting 3988 from 4008.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 997

Step 8:
If we divide 200 by 997, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 15440.0
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.

Going ahead to step 9:
The number 997 fits into 2000 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 15440.2
If we take 1994 away from 2000, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
The number 997 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 15440.2
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
The number 997 fits into 600 0 times, leaving a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 15440.2
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 15440.2 with a balance of 0.06.
