We're dividing 80784739 by 531 
We want to figure out the number of times 80784739 can be divided by 531.

Advancing to step 1:
When dividing 8 by 531, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 531

Let's proceed to step 2:
When dividing 80 by 531, we get 0 with 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 (7) from the dividend, attach it to 80 and continue: 807 / 531

Moving on to step 3:
807 divided by 531 is 1 with a remainder of 276.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 531 away from 807, we end up with 276.
Include the next digit (8) from the dividend after 276, then repeat: 2768 / 531

Moving on to step 4:
531 goes into 2768 5 times with a remainder of 113.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 2655 from 2768, we get 113.
Grab the next digit (4) from the dividend, add it to 113, then carry on: 1134 / 531

Going ahead to step 5:
The number 531 fits into 1134 2 times, leaving a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 152.0
The remainder is 72 after subtracting 1062 from 1134.
Bring next digit (7) of the dividend behind the 72 and repeat the process: 727 / 531

On to step 6:
531 can be fit into 727 1 times, resulting in a remainder of 196.
Write down 1 as next digit of the result. 
Result so far: 1521.0
If we subtract 531 from 727, we get 196.
Append the next digit (3) from the dividend to 196 and continue with: 1963 / 531

Going ahead to step 7:
531 goes into 1963 3 times with a remainder of 370.
Write down 3 as next digit of the result. 
Result so far: 15213.0
If we take 1593 away from 1963, we end up with 370.
Bring next digit (9) of the dividend behind the 370 and repeat the process: 3709 / 531

Let's proceed to step 8:
If we divide 3709 by 531, we get 6 and a remainder of 523.
Write down 6 as next digit of the result. 
Result so far: 152136.0
If we subtract 3186 from 3709, we get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Advancing to step 9:
531 can be fit into 5230 9 times, resulting in a remainder of 451.
Record the quotient 9 as the next digit in the result. 
Result so far: 152136.9
Subtract 4779 from 5230 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Advancing to step 10:
531 goes into 4510 8 times with a remainder of 262.
The number 8 becomes the next digit in our result. 
Result so far: 152136.98
Subtracting 4248 from 4510 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 11:
If we divide 2620 by 531, we get 4 and a remainder of 496.
The next digit of our result is 4. 
Result so far: 152136.984
If we subtract 2124 from 2620, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 12:
531 can be fit into 4960 9 times, resulting in a remainder of 181.
The next digit of our result is 9. 
Result so far: 152136.9849
Deduct 4779 from 4960 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Step 13:
If we divide 1810 by 531, we get 3 and a remainder of 217.
Put 3 as the next digit of the answer. 
Result so far: 152136.98493
If we take 1593 away from 1810, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 14:
531 can be fit into 2170 4 times, resulting in a remainder of 46.
The next digit of our result is 4. 
Result so far: 152136.984934
The remainder is 46 after subtracting 2124 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 15:
If we divide 460 by 531, we get 0 and a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 152136.984934
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
531 goes into 4600 8 times with a remainder of 352.
Record the quotient 8 as the next digit in the result. 
Result so far: 152136.98493408
Deduct 4248 from 4600 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Our division results in 152136.98493408 with a remaining 3.52e-07.
