15335056 ÷ 123 
Let's see how many times 123 fits into 15335056.

Step 1:
If we divide 1 by 123, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 123

Moving on to step 2:
15 divided by 123 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 123

Moving on to step 3:
153 divided by 123 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 123 away from 153, we end up with 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 123

Step 4:
The number 123 fits into 303 2 times, leaving a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 246 from 303 leaves us with 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 123

Moving on to step 5:
When dividing 575 by 123, we get 4 with a remainder of 83.
The next digit of our result is 4. 
Result so far: 124.0
If we take 492 away from 575, we end up with 83.
Fetch the next digit (0) from the dividend, attach it to 83 and continue: 830 / 123

Advancing to step 6:
If we divide 830 by 123, we get 6 and a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 1246.0
Deduct 738 from 830 and we're left with 92.
Fetch the next digit (5) from the dividend, attach it to 92 and continue: 925 / 123

Let's proceed to step 7:
123 goes into 925 7 times with a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 12467.0
The remainder is 64 after subtracting 861 from 925.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 123

Advancing to step 8:
If we divide 646 by 123, we get 5 and a remainder of 31.
The next digit of our result is 5. 
Result so far: 124675.0
If we subtract 615 from 646, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
The number 123 fits into 310 2 times, leaving a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 124675.2
Deduct 246 from 310 and we're left 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.

Step 10:
123 can be fit into 640 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 124675.25
Subtracting 615 from 640 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.

On to step 11:
250 divided by 123 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 124675.252
Deduct 246 from 250 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
123 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 124675.252
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
The number 123 fits into 400 3 times, leaving a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 124675.25203
If we subtract 369 from 400, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 14:
310 divided by 123 is 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 124675.252032
If we subtract 246 from 310, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
123 goes into 640 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 124675.2520325
Subtract 615 from 640 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 16:
If we divide 250 by 123, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 124675.25203252
If we take 246 away from 250, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 124675.25203252, and the remainder is 4e-09.
