We're dividing 77286690 by 507 
Our goal is to divide 77286690 by 507.

Let's proceed to step 1:
The number 507 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 507

Going ahead to step 2:
If we divide 77 by 507, we get 0 and a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (2) from the dividend, add it to 77, then carry on: 772 / 507

Moving on to step 3:
507 goes into 772 1 times with a remainder of 265.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 507 from 772, we get 265.
Include the next digit (8) from the dividend after 265, then repeat: 2658 / 507

Step 4:
507 can be fit into 2658 5 times, resulting in a remainder of 123.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 2535 from 2658 leaves us with 123.
Take the next digit (6) from the dividend and append it to 123, then repeat: 1236 / 507

Going ahead to step 5:
507 goes into 1236 2 times with a remainder of 222.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
The remainder is 222 after subtracting 1014 from 1236.
Take the next digit (6) from the dividend and append it to 222, then repeat: 2226 / 507

Going ahead to step 6:
507 can be fit into 2226 4 times, resulting in a remainder of 198.
Record the quotient 4 as the next digit in the result. 
Result so far: 1524.0
If we take 2028 away from 2226, we end up with 198.
Grab the next digit (9) from the dividend, add it to 198, then carry on: 1989 / 507

Going ahead to step 7:
507 goes into 1989 3 times with a remainder of 468.
The next digit of our result is 3. 
Result so far: 15243.0
Subtract 1521 from 1989 to get 468.
Include the next digit (0) from the dividend after 468, then repeat: 4680 / 507

Going ahead to step 8:
507 goes into 4680 9 times with a remainder of 117.
Put 9 as the next digit of the answer. 
Result so far: 152439.0
If we take 4563 away from 4680, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 9:
507 goes into 1170 2 times with a remainder of 156.
Write down 2 as next digit of the result. 
Result so far: 152439.2
Deduct 1014 from 1170 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 10:
If we divide 1560 by 507, we get 3 and a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 152439.23
If we take 1521 away from 1560, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
When dividing 390 by 507, we get 0 with a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 152439.23
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 12:
507 goes into 3900 7 times with a remainder of 351.
Put 7 as the next digit of the answer. 
Result so far: 152439.2307
If we subtract 3549 from 3900, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 13:
If we divide 3510 by 507, we get 6 and a remainder of 468.
The number 6 becomes the next digit in our result. 
Result so far: 152439.23076
Subtracting 3042 from 3510 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 14:
507 goes into 4680 9 times with a remainder of 117.
The number 9 becomes the next digit in our result. 
Result so far: 152439.230769
The remainder is 117 after subtracting 4563 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 15:
When dividing 1170 by 507, we get 2 with a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 152439.2307692
If we subtract 1014 from 1170, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 16:
The number 507 fits into 1560 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 152439.23076923
The remainder is 39 after subtracting 1521 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 152439.23076923 and a remainder of 3.9e-08.
