We're dividing 80401668 by 123 
Our goal is to divide 80401668 by 123.

Let's proceed to step 1:
8 divided by 123 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 123

Advancing to step 2:
123 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (4) from the dividend and append it to 80, then repeat: 804 / 123

Moving on to step 3:
If we divide 804 by 123, we get 6 and a remainder of 66.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 738 from 804 to get 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 123

Going ahead to step 4:
The number 123 fits into 660 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtracting 615 from 660 leaves us with 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 123

Let's proceed to step 5:
451 divided by 123 is 3 with a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 653.0
Subtracting 369 from 451 leaves us with 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 123

Going ahead to step 6:
When dividing 826 by 123, we get 6 with a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 6536.0
The remainder is 88 after subtracting 738 from 826.
Append the next digit (6) from the dividend to 88 and continue with: 886 / 123

Advancing to step 7:
123 goes into 886 7 times with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 65367.0
If we take 861 away from 886, we end up with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 123

Going ahead to step 8:
123 goes into 258 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 653672.0
If we take 246 away from 258, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
When dividing 120 by 123, we get 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 653672.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
When dividing 1200 by 123, we get 9 with a remainder of 93.
Use 9 as the next digit of our solution. 
Result so far: 653672.09
Deduct 1107 from 1200 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 11:
The number 123 fits into 930 7 times, leaving a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 653672.097
Deduct 861 from 930 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 12:
123 goes into 690 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 653672.0975
The remainder is 75 after subtracting 615 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
When dividing 750 by 123, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 653672.09756
Subtracting 738 from 750 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
The number 123 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 653672.09756
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 15:
When dividing 1200 by 123, we get 9 with a remainder of 93.
Write down 9 as next digit of the result. 
Result so far: 653672.0975609
Subtract 1107 from 1200 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 16:
If we divide 930 by 123, we get 7 and a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 653672.09756097
The remainder is 69 after subtracting 861 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The quotient of the division is 653672.09756097, and the remainder is 6.9e-08.
