80742387 ÷ 507 
We want to divide 80742387 by 507.

On to step 1:
If we divide 8 by 507, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 507

On to step 2:
If we divide 80 by 507, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (7) of the dividend behind the 80 and repeat the process: 807 / 507

Let's proceed to step 3:
If we divide 807 by 507, we get 1 and a remainder of 300.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 507 from 807 and we're left with 300.
Grab the next digit (4) from the dividend, add it to 300, then carry on: 3004 / 507

Step 4:
507 can be fit into 3004 5 times, resulting in a remainder of 469.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2535 away from 3004, we end up with 469.
Grab the next digit (2) from the dividend, add it to 469, then carry on: 4692 / 507

Let's proceed to step 5:
When dividing 4692 by 507, we get 9 with a remainder of 129.
The next digit of our result is 9. 
Result so far: 159.0
If we take 4563 away from 4692, we end up with 129.
Include the next digit (3) from the dividend after 129, then repeat: 1293 / 507

On to step 6:
507 can be fit into 1293 2 times, resulting in a remainder of 279.
The next digit of our result is 2. 
Result so far: 1592.0
If we take 1014 away from 1293, we end up with 279.
Bring next digit (8) of the dividend behind the 279 and repeat the process: 2798 / 507

Let's proceed to step 7:
The number 507 fits into 2798 5 times, leaving a remainder of 263.
Put 5 as the next digit of the answer. 
Result so far: 15925.0
If we subtract 2535 from 2798, we get 263.
Bring next digit (7) of the dividend behind the 263 and repeat the process: 2637 / 507

Step 8:
If we divide 2637 by 507, we get 5 and a remainder of 102.
Use 5 as the next digit of our solution. 
Result so far: 159255.0
Subtracting 2535 from 2637 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 9:
When dividing 1020 by 507, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 159255.2
If we take 1014 away from 1020, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
507 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 159255.2
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
When dividing 600 by 507, we get 1 with a remainder of 93.
The number 1 becomes the next digit in our result. 
Result so far: 159255.201
The remainder is 93 after subtracting 507 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 12:
When dividing 930 by 507, we get 1 with a remainder of 423.
Use 1 as the next digit of our solution. 
Result so far: 159255.2011
If we take 507 away from 930, we end up with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

The quotient of the division is 159255.2011, and the remainder is 0.00423.
