We look at the division of 66371273 by 507 
We're looking to find how many times 507 goes into 66371273.

Step 1:
The number 507 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 507

Advancing to step 2:
507 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 507

Step 3:
663 divided by 507 is 1 with a remainder of 156.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 507 from 663 and we're left with 156.
Bring next digit (7) of the dividend behind the 156 and repeat the process: 1567 / 507

On to step 4:
507 goes into 1567 3 times with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1521 from 1567, we get 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 507

Let's proceed to step 5:
The number 507 fits into 461 0 times, leaving a remainder of 461.
The next digit of our result is 0. 
Result so far: 130.0
Subtracting 0 from 461 leaves us with 461.
Bring next digit (2) of the dividend behind the 461 and repeat the process: 4612 / 507

On to step 6:
If we divide 4612 by 507, we get 9 and a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 1309.0
The remainder is 49 after subtracting 4563 from 4612.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 507

Step 7:
The number 507 fits into 497 0 times, leaving a remainder of 497.
Record the quotient 0 as the next digit in the result. 
Result so far: 13090.0
If we take 0 away from 497, we end up with 497.
Take the next digit (3) from the dividend and append it to 497, then repeat: 4973 / 507

Moving on to step 8:
4973 divided by 507 is 9 with a remainder of 410.
Record the quotient 9 as the next digit in the result. 
Result so far: 130909.0
Subtracting 4563 from 4973 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 9:
The number 507 fits into 4100 8 times, leaving a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 130909.8
If we take 4056 away from 4100, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
507 can be fit into 440 0 times, resulting in a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 130909.8
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
The number 507 fits into 4400 8 times, leaving a remainder of 344.
The next digit of our result is 8. 
Result so far: 130909.808
Subtract 4056 from 4400 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 12:
The number 507 fits into 3440 6 times, leaving a remainder of 398.
Write down 6 as next digit of the result. 
Result so far: 130909.8086
Subtracting 3042 from 3440 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 13:
When dividing 3980 by 507, we get 7 with a remainder of 431.
Use 7 as the next digit of our solution. 
Result so far: 130909.80867
If we subtract 3549 from 3980, we get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 14:
507 can be fit into 4310 8 times, resulting in a remainder of 254.
The number 8 becomes the next digit in our result. 
Result so far: 130909.808678
If we take 4056 away from 4310, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 15:
2540 divided by 507 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 130909.8086785
If we subtract 2535 from 2540, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 16:
50 divided by 507 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 130909.8086785
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 130909.8086785 with a remaining 5e-08.
