3887284 ÷ 997 
We want to divide 3887284 by 997.

Step 1:
When dividing 3 by 997, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 997

Moving on to step 2:
When dividing 38 by 997, we get 0 with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 997

On to step 3:
388 divided by 997 is 0 with a remainder of 388.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 388 and we're left with 388.
Grab the next digit (7) from the dividend, add it to 388, then carry on: 3887 / 997

Let's proceed to step 4:
The number 997 fits into 3887 3 times, leaving a remainder of 896.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 2991 from 3887 and we're left with 896.
Bring next digit (2) of the dividend behind the 896 and repeat the process: 8962 / 997

Step 5:
997 goes into 8962 8 times with a remainder of 986.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 7976 from 8962 to get 986.
Take the next digit (8) from the dividend and append it to 986, then repeat: 9868 / 997

Moving on to step 6:
If we divide 9868 by 997, we get 9 and a remainder of 895.
The number 9 becomes the next digit in our result. 
Result so far: 389.0
If we take 8973 away from 9868, we end up with 895.
Grab the next digit (4) from the dividend, add it to 895, then carry on: 8954 / 997

Advancing to step 7:
If we divide 8954 by 997, we get 8 and a remainder of 978.
Write down 8 as next digit of the result. 
Result so far: 3898.0
The remainder is 978 after subtracting 7976 from 8954.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9780, and continue the process.

Advancing to step 8:
997 can be fit into 9780 9 times, resulting in a remainder of 807.
Put 9 as the next digit of the answer. 
Result so far: 3898.9
The remainder is 807 after subtracting 8973 from 9780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

Step 9:
997 can be fit into 8070 8 times, resulting in a remainder of 94.
Record the quotient 8 as the next digit in the result. 
Result so far: 3898.98
The remainder is 94 after subtracting 7976 from 8070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 10:
The number 997 fits into 940 0 times, leaving a remainder of 940.
The next digit of our result is 0. 
Result so far: 3898.98
If we take 0 away from 940, we end up with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Step 11:
9400 divided by 997 is 9 with a remainder of 427.
Write down 9 as next digit of the result. 
Result so far: 3898.9809
Deduct 8973 from 9400 and we're left with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Let's proceed to step 12:
4270 divided by 997 is 4 with a remainder of 282.
Record the quotient 4 as the next digit in the result. 
Result so far: 3898.98094
If we subtract 3988 from 4270, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 13:
The number 997 fits into 2820 2 times, leaving a remainder of 826.
Put 2 as the next digit of the answer. 
Result so far: 3898.980942
If we subtract 1994 from 2820, we get 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Going ahead to step 14:
The number 997 fits into 8260 8 times, leaving a remainder of 284.
Write down 8 as next digit of the result. 
Result so far: 3898.9809428
If we take 7976 away from 8260, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 15:
If we divide 2840 by 997, we get 2 and a remainder of 846.
Record the quotient 2 as the next digit in the result. 
Result so far: 3898.98094282
If we subtract 1994 from 2840, we get 846.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

The final outcome is 3898.98094282, with a leftover of 8.46e-07.
