Let's divide 80999957 by 531
Let's see how many times 531 fits into 80999957.

Moving on to step 1:
531 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
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 531

Step 2:
The number 531 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.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 531

Step 3:
The number 531 fits into 809 1 times, leaving a remainder of 278.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 278 after subtracting 531 from 809.
Bring next digit (9) of the dividend behind the 278 and repeat the process: 2789 / 531

Moving on to step 4:
If we divide 2789 by 531, we get 5 and a remainder of 134.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 134 after subtracting 2655 from 2789.
Grab the next digit (9) from the dividend, add it to 134, then carry on: 1349 / 531

Advancing to step 5:
When dividing 1349 by 531, we get 2 with a remainder of 287.
Use 2 as the next digit of our solution. 
Result so far: 152.0
If we subtract 1062 from 1349, we get 287.
Bring next digit (9) of the dividend behind the 287 and repeat the process: 2879 / 531

Moving on to step 6:
531 can be fit into 2879 5 times, resulting in a remainder of 224.
Put 5 as the next digit of the answer. 
Result so far: 1525.0
Subtracting 2655 from 2879 leaves us with 224.
Append the next digit (5) from the dividend to 224 and continue with: 2245 / 531

On to step 7:
If we divide 2245 by 531, we get 4 and a remainder of 121.
The number 4 becomes the next digit in our result. 
Result so far: 15254.0
If we subtract 2124 from 2245, we get 121.
Include the next digit (7) from the dividend after 121, then repeat: 1217 / 531

Step 8:
If we divide 1217 by 531, we get 2 and a remainder of 155.
The next digit of our result is 2. 
Result so far: 152542.0
The remainder is 155 after subtracting 1062 from 1217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 9:
When dividing 1550 by 531, we get 2 with a remainder of 488.
Write down 2 as next digit of the result. 
Result so far: 152542.2
Subtracting 1062 from 1550 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 10:
531 goes into 4880 9 times with a remainder of 101.
Record the quotient 9 as the next digit in the result. 
Result so far: 152542.29
Subtracting 4779 from 4880 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 11:
The number 531 fits into 1010 1 times, leaving a remainder of 479.
The next digit of our result is 1. 
Result so far: 152542.291
The remainder is 479 after subtracting 531 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Advancing to step 12:
If we divide 4790 by 531, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 152542.2919
Deduct 4779 from 4790 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
When dividing 110 by 531, we get 0 with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 152542.2919
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 14:
The number 531 fits into 1100 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 152542.291902
Subtracting 1062 from 1100 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 15:
380 divided by 531 is 0 with a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 152542.291902
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 16:
If we divide 3800 by 531, we get 7 and a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 152542.29190207
If we take 3717 away from 3800, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The quotient of the division is 152542.29190207, and the remainder is 8.3e-08.
