We divide 84972456 by 509
Let's see how many times 509 fits into 84972456.

Let's proceed to step 1:
If we divide 8 by 509, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 509

Going ahead to step 2:
The number 509 fits into 84 0 times, leaving a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Take the next digit (9) from the dividend and append it to 84, then repeat: 849 / 509

Moving on to step 3:
849 divided by 509 is 1 with a remainder of 340.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 509 away from 849, we end up with 340.
Bring next digit (7) of the dividend behind the 340 and repeat the process: 3407 / 509

Going ahead to step 4:
When dividing 3407 by 509, we get 6 with a remainder of 353.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 3054 from 3407 to get 353.
Append the next digit (2) from the dividend to 353 and continue with: 3532 / 509

Moving on to step 5:
If we divide 3532 by 509, we get 6 and a remainder of 478.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
The remainder is 478 after subtracting 3054 from 3532.
Fetch the next digit (4) from the dividend, attach it to 478 and continue: 4784 / 509

Advancing to step 6:
509 can be fit into 4784 9 times, resulting in a remainder of 203.
Write down 9 as next digit of the result. 
Result so far: 1669.0
Deduct 4581 from 4784 and we're left with 203.
Fetch the next digit (5) from the dividend, attach it to 203 and continue: 2035 / 509

Moving on to step 7:
2035 divided by 509 is 3 with a remainder of 508.
The number 3 becomes the next digit in our result. 
Result so far: 16693.0
Deduct 1527 from 2035 and we're left with 508.
Bring next digit (6) of the dividend behind the 508 and repeat the process: 5086 / 509

Step 8:
5086 divided by 509 is 9 with a remainder of 505.
Record the quotient 9 as the next digit in the result. 
Result so far: 166939.0
Subtract 4581 from 5086 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 9:
509 can be fit into 5050 9 times, resulting in a remainder of 469.
The number 9 becomes the next digit in our result. 
Result so far: 166939.9
If we take 4581 away from 5050, we end up with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Moving on to step 10:
The number 509 fits into 4690 9 times, leaving a remainder of 109.
Use 9 as the next digit of our solution. 
Result so far: 166939.99
Deduct 4581 from 4690 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Our division results in 166939.99 with a remaining 0.109.
