We're dividing 69581587 by 663 
We want to divide 69581587 by 663.

Advancing to step 1:
When dividing 6 by 663, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 663

Advancing to step 2:
663 can be fit into 69 0 times, resulting in a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Bring next digit (5) of the dividend behind the 69 and repeat the process: 695 / 663

Going ahead to step 3:
The number 663 fits into 695 1 times, leaving a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 32 after subtracting 663 from 695.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 663

On to step 4:
The number 663 fits into 328 0 times, leaving a remainder of 328.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 328 and we're left with 328.
Include the next digit (1) from the dividend after 328, then repeat: 3281 / 663

On to step 5:
663 can be fit into 3281 4 times, resulting in a remainder of 629.
The next digit of our result is 4. 
Result so far: 104.0
If we take 2652 away from 3281, we end up with 629.
Append the next digit (5) from the dividend to 629 and continue with: 6295 / 663

Going ahead to step 6:
663 can be fit into 6295 9 times, resulting in a remainder of 328.
Write down 9 as next digit of the result. 
Result so far: 1049.0
Subtract 5967 from 6295 to get 328.
Take the next digit (8) from the dividend and append it to 328, then repeat: 3288 / 663

Let's proceed to step 7:
663 can be fit into 3288 4 times, resulting in a remainder of 636.
Use 4 as the next digit of our solution. 
Result so far: 10494.0
The remainder is 636 after subtracting 2652 from 3288.
Grab the next digit (7) from the dividend, add it to 636, then carry on: 6367 / 663

Going ahead to step 8:
663 goes into 6367 9 times with a remainder of 400.
The next digit of our result is 9. 
Result so far: 104949.0
If we take 5967 away from 6367, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 9:
663 goes into 4000 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 104949.6
Subtract 3978 from 4000 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
If we divide 220 by 663, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 104949.6
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
663 goes into 2200 3 times with a remainder of 211.
The next digit of our result is 3. 
Result so far: 104949.603
Deduct 1989 from 2200 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 12:
663 can be fit into 2110 3 times, resulting in a remainder of 121.
Record the quotient 3 as the next digit in the result. 
Result so far: 104949.6033
The remainder is 121 after subtracting 1989 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The final outcome is 104949.6033, with a leftover of 0.00121.
