We look at the division of 663883 by 69 
Our goal is to divide 663883 by 69.

On to step 1:
69 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 69

Advancing to step 2:
The number 69 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 69

On to step 3:
69 can be fit into 663 9 times, resulting in a remainder of 42.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 621 from 663, we get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 69

Advancing to step 4:
When dividing 428 by 69, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtract 414 from 428 to get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 69

Step 5:
69 can be fit into 148 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 962.0
Deduct 138 from 148 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 69

Going ahead to step 6:
The number 69 fits into 103 1 times, leaving a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 9621.0
The remainder is 34 after subtracting 69 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
69 can be fit into 340 4 times, resulting in a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 9621.4
Subtracting 276 from 340 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
The number 69 fits into 640 9 times, leaving a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 9621.49
Deduct 621 from 640 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
When dividing 190 by 69, we get 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 9621.492
The remainder is 52 after subtracting 138 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
520 divided by 69 is 7 with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 9621.4927
The remainder is 37 after subtracting 483 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
69 can be fit into 370 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 9621.49275
Subtracting 345 from 370 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
69 goes into 250 3 times with a remainder of 43.
The next digit of our result is 3. 
Result so far: 9621.492753
The remainder is 43 after subtracting 207 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
69 goes into 430 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 9621.4927536
The remainder is 16 after subtracting 414 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
69 goes into 160 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 9621.49275362
If we subtract 138 from 160, we 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.

The final outcome is 9621.49275362, with a leftover of 2.2e-08.
