Let's divide 77731404 by 123
We want to figure out the number of times 77731404 can be divided by 123.

On to step 1:
123 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 123

Step 2:
The number 123 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 123

Moving on to step 3:
123 goes into 777 6 times with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 738 from 777 and we're left with 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 123

Going ahead to step 4:
123 goes into 393 3 times with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 369 from 393 to get 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 123

Step 5:
The number 123 fits into 241 1 times, leaving a remainder of 118.
Put 1 as the next digit of the answer. 
Result so far: 631.0
If we take 123 away from 241, we end up with 118.
Fetch the next digit (4) from the dividend, attach it to 118 and continue: 1184 / 123

Going ahead to step 6:
123 can be fit into 1184 9 times, resulting in a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 6319.0
Deduct 1107 from 1184 and we're left with 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 123

On to step 7:
The number 123 fits into 770 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 63196.0
The remainder is 32 after subtracting 738 from 770.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 123

Advancing to step 8:
324 divided by 123 is 2 with a remainder of 78.
The next digit of our result is 2. 
Result so far: 631962.0
Subtracting 246 from 324 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
If we divide 780 by 123, we get 6 and a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 631962.6
If we take 738 away from 780, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
420 divided by 123 is 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 631962.63
The remainder is 51 after subtracting 369 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 11:
If we divide 510 by 123, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 631962.634
If we subtract 492 from 510, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
The number 123 fits into 180 1 times, leaving a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 631962.6341
If we subtract 123 from 180, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 13:
If we divide 570 by 123, we get 4 and a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 631962.63414
Subtracting 492 from 570 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 14:
123 goes into 780 6 times with a remainder of 42.
The next digit of our result is 6. 
Result so far: 631962.634146
If we subtract 738 from 780, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 15:
123 goes into 420 3 times with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 631962.6341463
Subtract 369 from 420 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 16:
123 can be fit into 510 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 631962.63414634
The remainder is 18 after subtracting 492 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 631962.63414634 and a remainder of 1.8e-08.
