80966363 ÷ 998 
Let's see how many times 998 fits into 80966363.

Step 1:
When dividing 8 by 998, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 998

Let's proceed to step 2:
998 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 998

Let's proceed to step 3:
When dividing 809 by 998, we get 0 with a remainder of 809.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 809, we get 809.
Include the next digit (6) from the dividend after 809, then repeat: 8096 / 998

On to step 4:
When dividing 8096 by 998, we get 8 with a remainder of 112.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 7984 from 8096 leaves us with 112.
Fetch the next digit (6) from the dividend, attach it to 112 and continue: 1126 / 998

Step 5:
If we divide 1126 by 998, we get 1 and a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 81.0
Deduct 998 from 1126 and we're left with 128.
Include the next digit (3) from the dividend after 128, then repeat: 1283 / 998

Moving on to step 6:
When dividing 1283 by 998, we get 1 with a remainder of 285.
The next digit of our result is 1. 
Result so far: 811.0
The remainder is 285 after subtracting 998 from 1283.
Take the next digit (6) from the dividend and append it to 285, then repeat: 2856 / 998

Step 7:
2856 divided by 998 is 2 with a remainder of 860.
Use 2 as the next digit of our solution. 
Result so far: 8112.0
Subtracting 1996 from 2856 leaves us with 860.
Fetch the next digit (3) from the dividend, attach it to 860 and continue: 8603 / 998

Moving on to step 8:
If we divide 8603 by 998, we get 8 and a remainder of 619.
Record the quotient 8 as the next digit in the result. 
Result so far: 81128.0
Subtracting 7984 from 8603 leaves us with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Let's proceed to step 9:
6190 divided by 998 is 6 with a remainder of 202.
Put 6 as the next digit of the answer. 
Result so far: 81128.6
Deduct 5988 from 6190 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 10:
When dividing 2020 by 998, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 81128.62
The remainder is 24 after subtracting 1996 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
998 goes into 240 0 times with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 81128.62
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 12:
When dividing 2400 by 998, we get 2 with a remainder of 404.
Put 2 as the next digit of the answer. 
Result so far: 81128.6202
If we take 1996 away from 2400, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 13:
998 can be fit into 4040 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 81128.62024
If we subtract 3992 from 4040, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
The number 998 fits into 480 0 times, leaving a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 81128.62024
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 15:
If we divide 4800 by 998, we get 4 and a remainder of 808.
Use 4 as the next digit of our solution. 
Result so far: 81128.6202404
Subtracting 3992 from 4800 leaves us with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

On to step 16:
998 can be fit into 8080 8 times, resulting in a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 81128.62024048
Subtracting 7984 from 8080 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 81128.62024048, with a leftover of 9.6e-08.
