80796431 ÷ 442 
We want to divide 80796431 by 442.

Advancing to step 1:
The number 442 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 442

On to step 2:
The number 442 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 442

Let's proceed to step 3:
When dividing 807 by 442, we get 1 with a remainder of 365.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 442 from 807 to get 365.
Fetch the next digit (9) from the dividend, attach it to 365 and continue: 3659 / 442

Going ahead to step 4:
If we divide 3659 by 442, we get 8 and a remainder of 123.
The next digit of our result is 8. 
Result so far: 18.0
If we take 3536 away from 3659, we end up with 123.
Take the next digit (6) from the dividend and append it to 123, then repeat: 1236 / 442

Step 5:
When dividing 1236 by 442, we get 2 with a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
If we take 884 away from 1236, we end up with 352.
Append the next digit (4) from the dividend to 352 and continue with: 3524 / 442

Moving on to step 6:
The number 442 fits into 3524 7 times, leaving a remainder of 430.
Use 7 as the next digit of our solution. 
Result so far: 1827.0
Subtract 3094 from 3524 to get 430.
Take the next digit (3) from the dividend and append it to 430, then repeat: 4303 / 442

Moving on to step 7:
4303 divided by 442 is 9 with a remainder of 325.
Put 9 as the next digit of the answer. 
Result so far: 18279.0
If we subtract 3978 from 4303, we get 325.
Grab the next digit (1) from the dividend, add it to 325, then carry on: 3251 / 442

Going ahead to step 8:
The number 442 fits into 3251 7 times, leaving a remainder of 157.
The next digit of our result is 7. 
Result so far: 182797.0
If we subtract 3094 from 3251, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
The number 442 fits into 1570 3 times, leaving a remainder of 244.
The number 3 becomes the next digit in our result. 
Result so far: 182797.3
The remainder is 244 after subtracting 1326 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 10:
If we divide 2440 by 442, we get 5 and a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 182797.35
Subtracting 2210 from 2440 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 11:
442 can be fit into 2300 5 times, resulting in a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 182797.355
The remainder is 90 after subtracting 2210 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 182797.355 with a remaining 0.009.
