72018220 ÷ 531 
Our goal is to divide 72018220 by 531.

Moving on to step 1:
When dividing 7 by 531, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 531

On to step 2:
531 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 531

Moving on to step 3:
531 can be fit into 720 1 times, resulting in a remainder of 189.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 189 after subtracting 531 from 720.
Append the next digit (1) from the dividend to 189 and continue with: 1891 / 531

Advancing to step 4:
1891 divided by 531 is 3 with a remainder of 298.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1593 from 1891, we get 298.
Take the next digit (8) from the dividend and append it to 298, then repeat: 2988 / 531

Let's proceed to step 5:
The number 531 fits into 2988 5 times, leaving a remainder of 333.
Write down 5 as next digit of the result. 
Result so far: 135.0
Deduct 2655 from 2988 and we're left with 333.
Bring next digit (2) of the dividend behind the 333 and repeat the process: 3332 / 531

Step 6:
3332 divided by 531 is 6 with a remainder of 146.
The next digit of our result is 6. 
Result so far: 1356.0
Subtract 3186 from 3332 to get 146.
Fetch the next digit (2) from the dividend, attach it to 146 and continue: 1462 / 531

Moving on to step 7:
531 can be fit into 1462 2 times, resulting in a remainder of 400.
Put 2 as the next digit of the answer. 
Result so far: 13562.0
If we take 1062 away from 1462, we end up with 400.
Take the next digit (0) from the dividend and append it to 400, then repeat: 4000 / 531

Moving on to step 8:
If we divide 4000 by 531, we get 7 and a remainder of 283.
The number 7 becomes the next digit in our result. 
Result so far: 135627.0
The remainder is 283 after subtracting 3717 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 9:
If we divide 2830 by 531, we get 5 and a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 135627.5
If we take 2655 away from 2830, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 10:
If we divide 1750 by 531, we get 3 and a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 135627.53
Subtracting 1593 from 1750 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 11:
531 goes into 1570 2 times with a remainder of 508.
The number 2 becomes the next digit in our result. 
Result so far: 135627.532
Subtracting 1062 from 1570 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 12:
If we divide 5080 by 531, we get 9 and a remainder of 301.
Use 9 as the next digit of our solution. 
Result so far: 135627.5329
The remainder is 301 after subtracting 4779 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 13:
If we divide 3010 by 531, we get 5 and a remainder of 355.
The number 5 becomes the next digit in our result. 
Result so far: 135627.53295
Deduct 2655 from 3010 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 14:
531 goes into 3550 6 times with a remainder of 364.
Record the quotient 6 as the next digit in the result. 
Result so far: 135627.532956
Subtract 3186 from 3550 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 15:
When dividing 3640 by 531, we get 6 with a remainder of 454.
Use 6 as the next digit of our solution. 
Result so far: 135627.5329566
The remainder is 454 after subtracting 3186 from 3640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

In conclusion, the division gives 135627.5329566 with a balance of 4.54e-06.
