We divide 2139003 by 996
We're looking to find how many times 996 goes into 2139003.

Moving on to step 1:
If we divide 2 by 996, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 996

On to step 2:
The number 996 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 996

On to step 3:
If we divide 213 by 996, we get 0 and a remainder of 213.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Fetch the next digit (9) from the dividend, attach it to 213 and continue: 2139 / 996

Moving on to step 4:
When dividing 2139 by 996, we get 2 with a remainder of 147.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1992 from 2139 and we're left with 147.
Fetch the next digit (0) from the dividend, attach it to 147 and continue: 1470 / 996

Moving on to step 5:
The number 996 fits into 1470 1 times, leaving a remainder of 474.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 996 away from 1470, we end up with 474.
Append the next digit (0) from the dividend to 474 and continue with: 4740 / 996

On to step 6:
996 goes into 4740 4 times with a remainder of 756.
Put 4 as the next digit of the answer. 
Result so far: 214.0
If we take 3984 away from 4740, we end up with 756.
Append the next digit (3) from the dividend to 756 and continue with: 7563 / 996

Going ahead to step 7:
996 goes into 7563 7 times with a remainder of 591.
Put 7 as the next digit of the answer. 
Result so far: 2147.0
The remainder is 591 after subtracting 6972 from 7563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

On to step 8:
5910 divided by 996 is 5 with a remainder of 930.
Write down 5 as next digit of the result. 
Result so far: 2147.5
If we subtract 4980 from 5910, we get 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9300, and continue the process.

Going ahead to step 9:
9300 divided by 996 is 9 with a remainder of 336.
The next digit of our result is 9. 
Result so far: 2147.59
Subtracting 8964 from 9300 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 10:
If we divide 3360 by 996, we get 3 and a remainder of 372.
The number 3 becomes the next digit in our result. 
Result so far: 2147.593
Subtract 2988 from 3360 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 11:
996 goes into 3720 3 times with a remainder of 732.
Put 3 as the next digit of the answer. 
Result so far: 2147.5933
Subtract 2988 from 3720 to get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

The final outcome is 2147.5933, with a leftover of 0.00732.
