We divide 2523694 by 663
We want to divide 2523694 by 663.

On to step 1:
The number 663 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 663

Let's proceed to step 2:
663 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 663

Moving on to step 3:
If we divide 252 by 663, we get 0 and a remainder of 252.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 252 leaves us with 252.
Include the next digit (3) from the dividend after 252, then repeat: 2523 / 663

On to step 4:
The number 663 fits into 2523 3 times, leaving a remainder of 534.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1989 from 2523 to get 534.
Bring next digit (6) of the dividend behind the 534 and repeat the process: 5346 / 663

Step 5:
663 can be fit into 5346 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 38.0
Deduct 5304 from 5346 and we're left with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 663

Advancing to step 6:
When dividing 429 by 663, we get 0 with a remainder of 429.
Put 0 as the next digit of the answer. 
Result so far: 380.0
The remainder is 429 after subtracting 0 from 429.
Include the next digit (4) from the dividend after 429, then repeat: 4294 / 663

Going ahead to step 7:
663 can be fit into 4294 6 times, resulting in a remainder of 316.
Record the quotient 6 as the next digit in the result. 
Result so far: 3806.0
If we take 3978 away from 4294, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 8:
3160 divided by 663 is 4 with a remainder of 508.
The next digit of our result is 4. 
Result so far: 3806.4
Subtracting 2652 from 3160 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 9:
If we divide 5080 by 663, we get 7 and a remainder of 439.
Write down 7 as next digit of the result. 
Result so far: 3806.47
If we take 4641 away from 5080, we end up with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Let's proceed to step 10:
663 goes into 4390 6 times with a remainder of 412.
Use 6 as the next digit of our solution. 
Result so far: 3806.476
Subtracting 3978 from 4390 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 11:
4120 divided by 663 is 6 with a remainder of 142.
Record the quotient 6 as the next digit in the result. 
Result so far: 3806.4766
Subtract 3978 from 4120 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The quotient of the division is 3806.4766, and the remainder is 0.00142.
