Let's divide 53664365 by 123
Our goal is to divide 53664365 by 123.

Going ahead to step 1:
5 divided by 123 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 123

Moving on to step 2:
123 can be fit into 53 0 times, resulting in a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 123

Advancing to step 3:
The number 123 fits into 536 4 times, leaving a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 44 after subtracting 492 from 536.
Bring next digit (6) of the dividend behind the 44 and repeat the process: 446 / 123

Step 4:
446 divided by 123 is 3 with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we subtract 369 from 446, we get 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 123

Let's proceed to step 5:
If we divide 774 by 123, we get 6 and a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 436.0
If we subtract 738 from 774, we get 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 123

Step 6:
The number 123 fits into 363 2 times, leaving a remainder of 117.
Put 2 as the next digit of the answer. 
Result so far: 4362.0
Deduct 246 from 363 and we're left with 117.
Bring next digit (6) of the dividend behind the 117 and repeat the process: 1176 / 123

Let's proceed to step 7:
When dividing 1176 by 123, we get 9 with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 43629.0
Subtract 1107 from 1176 to get 69.
Take the next digit (5) from the dividend and append it to 69, then repeat: 695 / 123

Moving on to step 8:
123 goes into 695 5 times with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 436295.0
Subtract 615 from 695 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
800 divided by 123 is 6 with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 436295.6
If we subtract 738 from 800, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
123 goes into 620 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 436295.65
Subtracting 615 from 620 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
123 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 436295.65
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
If we divide 500 by 123, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 436295.6504
Subtract 492 from 500 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
If we divide 80 by 123, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 436295.6504
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
123 goes into 800 6 times with a remainder of 62.
The next digit of our result is 6. 
Result so far: 436295.650406
The remainder is 62 after subtracting 738 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 15:
When dividing 620 by 123, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 436295.6504065
If we subtract 615 from 620, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 16:
The number 123 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 436295.6504065
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 436295.6504065, with a leftover of 5e-08.
