We look at the division of 39201770 by 507 
We're looking to find how many times 507 goes into 39201770.

Advancing to step 1:
The number 507 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 507

Let's proceed to step 2:
39 divided by 507 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 507

Advancing to step 3:
When dividing 392 by 507, we get 0 with a remainder of 392.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 392, we end up with 392.
Include the next digit (0) from the dividend after 392, then repeat: 3920 / 507

Step 4:
If we divide 3920 by 507, we get 7 and a remainder of 371.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 3549 from 3920 and we're left with 371.
Include the next digit (1) from the dividend after 371, then repeat: 3711 / 507

Moving on to step 5:
If we divide 3711 by 507, we get 7 and a remainder of 162.
Put 7 as the next digit of the answer. 
Result so far: 77.0
If we take 3549 away from 3711, we end up with 162.
Take the next digit (7) from the dividend and append it to 162, then repeat: 1627 / 507

Step 6:
507 goes into 1627 3 times with a remainder of 106.
Put 3 as the next digit of the answer. 
Result so far: 773.0
Deduct 1521 from 1627 and we're left with 106.
Bring next digit (7) of the dividend behind the 106 and repeat the process: 1067 / 507

On to step 7:
The number 507 fits into 1067 2 times, leaving a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 7732.0
The remainder is 53 after subtracting 1014 from 1067.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 507

Step 8:
The number 507 fits into 530 1 times, leaving a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 77321.0
Subtract 507 from 530 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
When dividing 230 by 507, we get 0 with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 77321.0
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 10:
507 goes into 2300 4 times with a remainder of 272.
Write down 4 as next digit of the result. 
Result so far: 77321.04
If we subtract 2028 from 2300, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 11:
If we divide 2720 by 507, we get 5 and a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 77321.045
Subtract 2535 from 2720 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 12:
The number 507 fits into 1850 3 times, leaving a remainder of 329.
The number 3 becomes the next digit in our result. 
Result so far: 77321.0453
The remainder is 329 after subtracting 1521 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 13:
507 can be fit into 3290 6 times, resulting in a remainder of 248.
Use 6 as the next digit of our solution. 
Result so far: 77321.04536
Subtracting 3042 from 3290 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 14:
507 can be fit into 2480 4 times, resulting in a remainder of 452.
The number 4 becomes the next digit in our result. 
Result so far: 77321.045364
If we take 2028 away from 2480, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 15:
If we divide 4520 by 507, we get 8 and a remainder of 464.
Put 8 as the next digit of the answer. 
Result so far: 77321.0453648
If we subtract 4056 from 4520, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 16:
4640 divided by 507 is 9 with a remainder of 77.
The next digit of our result is 9. 
Result so far: 77321.04536489
The remainder is 77 after subtracting 4563 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final outcome is 77321.04536489, with a leftover of 7.7e-08.
