We look at the division of 75148372 by 507 
We're looking to find how many times 507 goes into 75148372.

Step 1:
507 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 507

Step 2:
If we divide 75 by 507, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 507

Going ahead to step 3:
When dividing 751 by 507, we get 1 with a remainder of 244.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 507 from 751 to get 244.
Take the next digit (4) from the dividend and append it to 244, then repeat: 2444 / 507

Going ahead to step 4:
2444 divided by 507 is 4 with a remainder of 416.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 2028 from 2444, we get 416.
Bring next digit (8) of the dividend behind the 416 and repeat the process: 4168 / 507

Moving on to step 5:
The number 507 fits into 4168 8 times, leaving a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
If we subtract 4056 from 4168, we get 112.
Include the next digit (3) from the dividend after 112, then repeat: 1123 / 507

Moving on to step 6:
When dividing 1123 by 507, we get 2 with a remainder of 109.
Write down 2 as next digit of the result. 
Result so far: 1482.0
Subtract 1014 from 1123 to get 109.
Grab the next digit (7) from the dividend, add it to 109, then carry on: 1097 / 507

Going ahead to step 7:
The number 507 fits into 1097 2 times, leaving a remainder of 83.
The number 2 becomes the next digit in our result. 
Result so far: 14822.0
If we take 1014 away from 1097, we end up with 83.
Bring next digit (2) of the dividend behind the 83 and repeat the process: 832 / 507

Going ahead to step 8:
832 divided by 507 is 1 with a remainder of 325.
Write down 1 as next digit of the result. 
Result so far: 148221.0
Subtracting 507 from 832 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 9:
When dividing 3250 by 507, we get 6 with a remainder of 208.
The next digit of our result is 6. 
Result so far: 148221.6
If we subtract 3042 from 3250, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 10:
2080 divided by 507 is 4 with a remainder of 52.
The next digit of our result is 4. 
Result so far: 148221.64
If we subtract 2028 from 2080, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
The number 507 fits into 520 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 148221.641
If we subtract 507 from 520, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
When dividing 130 by 507, we get 0 with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 148221.641
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 13:
507 goes into 1300 2 times with a remainder of 286.
Use 2 as the next digit of our solution. 
Result so far: 148221.64102
The remainder is 286 after subtracting 1014 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 14:
If we divide 2860 by 507, we get 5 and a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 148221.641025
Subtracting 2535 from 2860 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 15:
When dividing 3250 by 507, we get 6 with a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 148221.6410256
Subtracting 3042 from 3250 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 16:
If we divide 2080 by 507, we get 4 and a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 148221.64102564
If we subtract 2028 from 2080, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 148221.64102564 and a remainder of 5.2e-08.
