We look at the division of 71771910 by 123 
Let's see how many times 123 fits into 71771910.

Going ahead to step 1:
123 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 123

Going ahead to step 2:
When dividing 71 by 123, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (7) from the dividend to 71 and continue with: 717 / 123

Let's proceed to step 3:
If we divide 717 by 123, we get 5 and a remainder of 102.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 615 from 717, we get 102.
Include the next digit (7) from the dividend after 102, then repeat: 1027 / 123

On to step 4:
123 goes into 1027 8 times with a remainder of 43.
The next digit of our result is 8. 
Result so far: 58.0
Deduct 984 from 1027 and we're left with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 123

Advancing to step 5:
If we divide 431 by 123, we get 3 and a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 583.0
Deduct 369 from 431 and we're left with 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 123

Let's proceed to step 6:
The number 123 fits into 629 5 times, leaving a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 5835.0
If we take 615 away from 629, we end up with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 123

On to step 7:
123 goes into 141 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 58351.0
Subtract 123 from 141 to get 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 123

Let's proceed to step 8:
The number 123 fits into 180 1 times, leaving a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 583511.0
The remainder is 57 after subtracting 123 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
123 can be fit into 570 4 times, resulting in a remainder of 78.
The next digit of our result is 4. 
Result so far: 583511.4
If we take 492 away from 570, we end up 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.

Moving on to step 10:
780 divided by 123 is 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 583511.46
Subtract 738 from 780 to 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.

Let's proceed to step 11:
123 goes into 420 3 times with a remainder of 51.
The next digit of our result is 3. 
Result so far: 583511.463
Subtracting 369 from 420 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 12:
When dividing 510 by 123, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 583511.4634
Subtract 492 from 510 to 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.

Going ahead to step 13:
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: 583511.46341
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.

On to step 14:
The number 123 fits into 570 4 times, leaving a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 583511.463414
The remainder is 78 after subtracting 492 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 15:
780 divided by 123 is 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 583511.4634146
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.

Going ahead to step 16:
The number 123 fits into 420 3 times, leaving a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 583511.46341463
If we subtract 369 from 420, we 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.

After the division, we end up with 583511.46341463 and a remainder of 5.1e-08.
