23954817 ÷ 661 
Our goal is to divide 23954817 by 661.

On to step 1:
2 divided by 661 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 661

Step 2:
If we divide 23 by 661, we get 0 and a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 661

Step 3:
When dividing 239 by 661, we get 0 with a remainder of 239.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 239 and we're left with 239.
Take the next digit (5) from the dividend and append it to 239, then repeat: 2395 / 661

Let's proceed to step 4:
When dividing 2395 by 661, we get 3 with a remainder of 412.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1983 from 2395 and we're left with 412.
Fetch the next digit (4) from the dividend, attach it to 412 and continue: 4124 / 661

Moving on to step 5:
4124 divided by 661 is 6 with a remainder of 158.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 158 after subtracting 3966 from 4124.
Fetch the next digit (8) from the dividend, attach it to 158 and continue: 1588 / 661

On to step 6:
If we divide 1588 by 661, we get 2 and a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
Subtracting 1322 from 1588 leaves us with 266.
Take the next digit (1) from the dividend and append it to 266, then repeat: 2661 / 661

Moving on to step 7:
When dividing 2661 by 661, we get 4 with a remainder of 17.
The next digit of our result is 4. 
Result so far: 3624.0
Subtract 2644 from 2661 to get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 661

Step 8:
661 can be fit into 177 0 times, resulting in a remainder of 177.
Record the quotient 0 as the next digit in the result. 
Result so far: 36240.0
If we take 0 away from 177, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 9:
661 goes into 1770 2 times with a remainder of 448.
Write down 2 as next digit of the result. 
Result so far: 36240.2
The remainder is 448 after subtracting 1322 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 10:
661 goes into 4480 6 times with a remainder of 514.
The number 6 becomes the next digit in our result. 
Result so far: 36240.26
If we take 3966 away from 4480, we end up with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

On to step 11:
661 goes into 5140 7 times with a remainder of 513.
Record the quotient 7 as the next digit in the result. 
Result so far: 36240.267
Subtract 4627 from 5140 to get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Moving on to step 12:
661 can be fit into 5130 7 times, resulting in a remainder of 503.
Record the quotient 7 as the next digit in the result. 
Result so far: 36240.2677
If we take 4627 away from 5130, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

The final outcome is 36240.2677, with a leftover of 0.00503.
