We divide 72486816 by 509
We're looking to find how many times 509 goes into 72486816.

Step 1:
When dividing 7 by 509, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 509

Going ahead to step 2:
72 divided by 509 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Bring next digit (4) of the dividend behind the 72 and repeat the process: 724 / 509

Advancing to step 3:
When dividing 724 by 509, we get 1 with a remainder of 215.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 215 after subtracting 509 from 724.
Fetch the next digit (8) from the dividend, attach it to 215 and continue: 2158 / 509

Let's proceed to step 4:
The number 509 fits into 2158 4 times, leaving a remainder of 122.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2036 from 2158, we get 122.
Fetch the next digit (6) from the dividend, attach it to 122 and continue: 1226 / 509

Advancing to step 5:
When dividing 1226 by 509, we get 2 with a remainder of 208.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtract 1018 from 1226 to get 208.
Append the next digit (8) from the dividend to 208 and continue with: 2088 / 509

Going ahead to step 6:
When dividing 2088 by 509, we get 4 with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 1424.0
Subtract 2036 from 2088 to get 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 509

Going ahead to step 7:
521 divided by 509 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 14241.0
The remainder is 12 after subtracting 509 from 521.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 509

Advancing to step 8:
If we divide 126 by 509, we get 0 and a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 142410.0
Deduct 0 from 126 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 9:
If we divide 1260 by 509, we get 2 and a remainder of 242.
Put 2 as the next digit of the answer. 
Result so far: 142410.2
Deduct 1018 from 1260 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 10:
When dividing 2420 by 509, we get 4 with a remainder of 384.
Write down 4 as next digit of the result. 
Result so far: 142410.24
The remainder is 384 after subtracting 2036 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 11:
When dividing 3840 by 509, we get 7 with a remainder of 277.
The next digit of our result is 7. 
Result so far: 142410.247
Deduct 3563 from 3840 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Let's proceed to step 12:
2770 divided by 509 is 5 with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 142410.2475
Deduct 2545 from 2770 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 13:
The number 509 fits into 2250 4 times, leaving a remainder of 214.
Use 4 as the next digit of our solution. 
Result so far: 142410.24754
Deduct 2036 from 2250 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 14:
If we divide 2140 by 509, we get 4 and a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 142410.247544
If we subtract 2036 from 2140, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 142410.247544, with a leftover of 1.04e-05.
