80315990 ÷ 944 
Our goal is to divide 80315990 by 944.

Moving on to step 1:
944 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 944

On to step 2:
The number 944 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 944

Let's proceed to step 3:
944 can be fit into 803 0 times, resulting in a remainder of 803.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 803, we get 803.
Include the next digit (1) from the dividend after 803, then repeat: 8031 / 944

On to step 4:
8031 divided by 944 is 8 with a remainder of 479.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7552 away from 8031, we end up with 479.
Fetch the next digit (5) from the dividend, attach it to 479 and continue: 4795 / 944

Moving on to step 5:
If we divide 4795 by 944, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtract 4720 from 4795 to get 75.
Include the next digit (9) from the dividend after 75, then repeat: 759 / 944

Moving on to step 6:
When dividing 759 by 944, we get 0 with a remainder of 759.
Record the quotient 0 as the next digit in the result. 
Result so far: 850.0
If we subtract 0 from 759, we get 759.
Fetch the next digit (9) from the dividend, attach it to 759 and continue: 7599 / 944

Going ahead to step 7:
The number 944 fits into 7599 8 times, leaving a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 8508.0
Subtract 7552 from 7599 to get 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 944

Advancing to step 8:
The number 944 fits into 470 0 times, leaving a remainder of 470.
Write down 0 as next digit of the result. 
Result so far: 85080.0
The remainder is 470 after subtracting 0 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 9:
4700 divided by 944 is 4 with a remainder of 924.
The number 4 becomes the next digit in our result. 
Result so far: 85080.4
The remainder is 924 after subtracting 3776 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9240, and continue the process.

Going ahead to step 10:
The number 944 fits into 9240 9 times, leaving a remainder of 744.
Write down 9 as next digit of the result. 
Result so far: 85080.49
Subtracting 8496 from 9240 leaves us with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Advancing to step 11:
944 goes into 7440 7 times with a remainder of 832.
Write down 7 as next digit of the result. 
Result so far: 85080.497
Subtract 6608 from 7440 to get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Going ahead to step 12:
944 goes into 8320 8 times with a remainder of 768.
The number 8 becomes the next digit in our result. 
Result so far: 85080.4978
The remainder is 768 after subtracting 7552 from 8320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

On to step 13:
If we divide 7680 by 944, we get 8 and a remainder of 128.
The next digit of our result is 8. 
Result so far: 85080.49788
If we subtract 7552 from 7680, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 85080.49788, and the remainder is 0.000128.
