We look at the division of 80121789 by 992 
Let's see how many times 992 fits into 80121789.

Step 1:
992 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 992

Step 2:
992 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 992

On to step 3:
If we divide 801 by 992, we get 0 and a remainder of 801.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 801, we end up with 801.
Take the next digit (2) from the dividend and append it to 801, then repeat: 8012 / 992

Going ahead to step 4:
When dividing 8012 by 992, we get 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 7936 from 8012 leaves us with 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 992

Step 5:
The number 992 fits into 761 0 times, leaving a remainder of 761.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 761 leaves us with 761.
Include the next digit (7) from the dividend after 761, then repeat: 7617 / 992

Step 6:
992 goes into 7617 7 times with a remainder of 673.
Record the quotient 7 as the next digit in the result. 
Result so far: 807.0
Subtracting 6944 from 7617 leaves us with 673.
Grab the next digit (8) from the dividend, add it to 673, then carry on: 6738 / 992

Let's proceed to step 7:
If we divide 6738 by 992, we get 6 and a remainder of 786.
Write down 6 as next digit of the result. 
Result so far: 8076.0
Subtracting 5952 from 6738 leaves us with 786.
Take the next digit (9) from the dividend and append it to 786, then repeat: 7869 / 992

Advancing to step 8:
When dividing 7869 by 992, we get 7 with a remainder of 925.
Write down 7 as next digit of the result. 
Result so far: 80767.0
If we take 6944 away from 7869, we end up with 925.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9250, and continue the process.

On to step 9:
9250 divided by 992 is 9 with a remainder of 322.
Write down 9 as next digit of the result. 
Result so far: 80767.9
Deduct 8928 from 9250 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 10:
992 can be fit into 3220 3 times, resulting in a remainder of 244.
The number 3 becomes the next digit in our result. 
Result so far: 80767.93
If we subtract 2976 from 3220, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 11:
When dividing 2440 by 992, we get 2 with a remainder of 456.
Write down 2 as next digit of the result. 
Result so far: 80767.932
The remainder is 456 after subtracting 1984 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 12:
The number 992 fits into 4560 4 times, leaving a remainder of 592.
Use 4 as the next digit of our solution. 
Result so far: 80767.9324
If we take 3968 away from 4560, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 13:
When dividing 5920 by 992, we get 5 with a remainder of 960.
Use 5 as the next digit of our solution. 
Result so far: 80767.93245
Subtract 4960 from 5920 to get 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Advancing to step 14:
9600 divided by 992 is 9 with a remainder of 672.
The next digit of our result is 9. 
Result so far: 80767.932459
Subtract 8928 from 9600 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 15:
992 can be fit into 6720 6 times, resulting in a remainder of 768.
The next digit of our result is 6. 
Result so far: 80767.9324596
If we subtract 5952 from 6720, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Going ahead to step 16:
992 can be fit into 7680 7 times, resulting in a remainder of 736.
The next digit of our result is 7. 
Result so far: 80767.93245967
If we subtract 6944 from 7680, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The quotient of the division is 80767.93245967, and the remainder is 7.36e-07.
