Let's divide 23159211 by 661
Our goal is to divide 23159211 by 661.

Let's proceed to step 1:
The number 661 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 661

Advancing to step 2:
The number 661 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 661

Moving on to step 3:
661 can be fit into 231 0 times, resulting in a remainder of 231.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 231 after subtracting 0 from 231.
Include the next digit (5) from the dividend after 231, then repeat: 2315 / 661

Advancing to step 4:
If we divide 2315 by 661, we get 3 and a remainder of 332.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 1983 from 2315, we get 332.
Append the next digit (9) from the dividend to 332 and continue with: 3329 / 661

Going ahead to step 5:
661 goes into 3329 5 times with a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 3305 from 3329 and we're left with 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 661

Let's proceed to step 6:
242 divided by 661 is 0 with a remainder of 242.
Write down 0 as next digit of the result. 
Result so far: 350.0
If we subtract 0 from 242, we get 242.
Append the next digit (1) from the dividend to 242 and continue with: 2421 / 661

Advancing to step 7:
661 can be fit into 2421 3 times, resulting in a remainder of 438.
The next digit of our result is 3. 
Result so far: 3503.0
If we subtract 1983 from 2421, we get 438.
Append the next digit (1) from the dividend to 438 and continue with: 4381 / 661

Going ahead to step 8:
661 can be fit into 4381 6 times, resulting in a remainder of 415.
The number 6 becomes the next digit in our result. 
Result so far: 35036.0
Subtracting 3966 from 4381 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 9:
661 can be fit into 4150 6 times, resulting in a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 35036.6
Deduct 3966 from 4150 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 10:
661 can be fit into 1840 2 times, resulting in a remainder of 518.
Put 2 as the next digit of the answer. 
Result so far: 35036.62
Subtracting 1322 from 1840 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

On to step 11:
When dividing 5180 by 661, we get 7 with a remainder of 553.
Record the quotient 7 as the next digit in the result. 
Result so far: 35036.627
Subtracting 4627 from 5180 leaves us with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Going ahead to step 12:
The number 661 fits into 5530 8 times, leaving a remainder of 242.
Record the quotient 8 as the next digit in the result. 
Result so far: 35036.6278
If we take 5288 away from 5530, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 13:
The number 661 fits into 2420 3 times, leaving a remainder of 437.
The next digit of our result is 3. 
Result so far: 35036.62783
The remainder is 437 after subtracting 1983 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

On to step 14:
When dividing 4370 by 661, we get 6 with a remainder of 404.
Write down 6 as next digit of the result. 
Result so far: 35036.627836
Deduct 3966 from 4370 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 15:
If we divide 4040 by 661, we get 6 and a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 35036.6278366
If we subtract 3966 from 4040, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 35036.6278366 with a remainder of 7.4e-07.
