We're dividing 18416957 by 663 
Our goal is to divide 18416957 by 663.

On to step 1:
The number 663 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 663

Advancing to step 2:
The number 663 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 663

Moving on to step 3:
If we divide 184 by 663, we get 0 and a remainder of 184.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 184 after subtracting 0 from 184.
Bring next digit (1) of the dividend behind the 184 and repeat the process: 1841 / 663

Step 4:
1841 divided by 663 is 2 with a remainder of 515.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1326 from 1841 and we're left with 515.
Include the next digit (6) from the dividend after 515, then repeat: 5156 / 663

Going ahead to step 5:
663 goes into 5156 7 times with a remainder of 515.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 4641 from 5156 and we're left with 515.
Append the next digit (9) from the dividend to 515 and continue with: 5159 / 663

Moving on to step 6:
The number 663 fits into 5159 7 times, leaving a remainder of 518.
Use 7 as the next digit of our solution. 
Result so far: 277.0
Deduct 4641 from 5159 and we're left with 518.
Bring next digit (5) of the dividend behind the 518 and repeat the process: 5185 / 663

Going ahead to step 7:
The number 663 fits into 5185 7 times, leaving a remainder of 544.
The number 7 becomes the next digit in our result. 
Result so far: 2777.0
Deduct 4641 from 5185 and we're left with 544.
Include the next digit (7) from the dividend after 544, then repeat: 5447 / 663

Step 8:
663 goes into 5447 8 times with a remainder of 143.
Record the quotient 8 as the next digit in the result. 
Result so far: 27778.0
Subtract 5304 from 5447 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 9:
The number 663 fits into 1430 2 times, leaving a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 27778.2
If we take 1326 away from 1430, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 10:
If we divide 1040 by 663, we get 1 and a remainder of 377.
Record the quotient 1 as the next digit in the result. 
Result so far: 27778.21
The remainder is 377 after subtracting 663 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 11:
663 goes into 3770 5 times with a remainder of 455.
Put 5 as the next digit of the answer. 
Result so far: 27778.215
Subtract 3315 from 3770 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Let's proceed to step 12:
When dividing 4550 by 663, we get 6 with a remainder of 572.
Write down 6 as next digit of the result. 
Result so far: 27778.2156
The remainder is 572 after subtracting 3978 from 4550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 13:
When dividing 5720 by 663, we get 8 with a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 27778.21568
Deduct 5304 from 5720 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 14:
When dividing 4160 by 663, we get 6 with a remainder of 182.
Use 6 as the next digit of our solution. 
Result so far: 27778.215686
If we take 3978 away from 4160, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 15:
When dividing 1820 by 663, we get 2 with a remainder of 494.
Put 2 as the next digit of the answer. 
Result so far: 27778.2156862
Deduct 1326 from 1820 and we're left with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 16:
663 goes into 4940 7 times with a remainder of 299.
Put 7 as the next digit of the answer. 
Result so far: 27778.21568627
If we take 4641 away from 4940, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

The final outcome is 27778.21568627, with a leftover of 2.99e-07.
