663945 ÷ 69 
We want to divide 663945 by 69.

Going ahead to step 1:
69 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 69

Advancing to step 2:
69 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 69

Step 3:
The number 69 fits into 663 9 times, leaving 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.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 69

Going ahead to step 4:
69 goes into 429 6 times with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Subtracting 414 from 429 leaves us with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 69

On to step 5:
The number 69 fits into 154 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 962.0
Deduct 138 from 154 and we're left with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 69

Moving on to step 6:
If we divide 165 by 69, we get 2 and a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 9622.0
If we subtract 138 from 165, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
If we divide 270 by 69, we get 3 and a remainder of 63.
The next digit of our result is 3. 
Result so far: 9622.3
If we take 207 away from 270, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 8:
69 can be fit into 630 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 9622.39
Deduct 621 from 630 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
69 can be fit into 90 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 9622.391
The remainder is 21 after subtracting 69 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
69 can be fit into 210 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 9622.3913
Deduct 207 from 210 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
The number 69 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9622.3913
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
The number 69 fits into 300 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 9622.391304
If we subtract 276 from 300, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
240 divided by 69 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 9622.3913043
If we subtract 207 from 240, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 14:
330 divided by 69 is 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 9622.39130434
Subtracting 276 from 330 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 9622.39130434 with a remainder of 5.4e-08.
