We're dividing 13201221 by 531 
Our goal is to divide 13201221 by 531.

Going ahead to step 1:
531 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 531

Moving on to step 2:
13 divided by 531 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 531

Step 3:
The number 531 fits into 132 0 times, leaving a remainder of 132.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 132 to get 132.
Bring next digit (0) of the dividend behind the 132 and repeat the process: 1320 / 531

Moving on to step 4:
1320 divided by 531 is 2 with a remainder of 258.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1062 from 1320, we get 258.
Grab the next digit (1) from the dividend, add it to 258, then carry on: 2581 / 531

Advancing to step 5:
2581 divided by 531 is 4 with a remainder of 457.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 457 after subtracting 2124 from 2581.
Take the next digit (2) from the dividend and append it to 457, then repeat: 4572 / 531

Let's proceed to step 6:
If we divide 4572 by 531, we get 8 and a remainder of 324.
The next digit of our result is 8. 
Result so far: 248.0
If we subtract 4248 from 4572, we get 324.
Grab the next digit (2) from the dividend, add it to 324, then carry on: 3242 / 531

Step 7:
When dividing 3242 by 531, we get 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 2486.0
The remainder is 56 after subtracting 3186 from 3242.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 531

On to step 8:
If we divide 561 by 531, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 24861.0
The remainder is 30 after subtracting 531 from 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
If we divide 300 by 531, we get 0 and a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 24861.0
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 10:
The number 531 fits into 3000 5 times, leaving a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 24861.05
Subtracting 2655 from 3000 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 11:
531 goes into 3450 6 times with a remainder of 264.
Record the quotient 6 as the next digit in the result. 
Result so far: 24861.056
If we take 3186 away from 3450, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 12:
When dividing 2640 by 531, we get 4 with a remainder of 516.
Use 4 as the next digit of our solution. 
Result so far: 24861.0564
Deduct 2124 from 2640 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 13:
If we divide 5160 by 531, we get 9 and a remainder of 381.
The next digit of our result is 9. 
Result so far: 24861.05649
The remainder is 381 after subtracting 4779 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Step 14:
When dividing 3810 by 531, we get 7 with a remainder of 93.
Record the quotient 7 as the next digit in the result. 
Result so far: 24861.056497
Deduct 3717 from 3810 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 15:
When dividing 930 by 531, we get 1 with a remainder of 399.
Write down 1 as next digit of the result. 
Result so far: 24861.0564971
Subtracting 531 from 930 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Let's proceed to step 16:
The number 531 fits into 3990 7 times, leaving a remainder of 273.
Record the quotient 7 as the next digit in the result. 
Result so far: 24861.05649717
If we take 3717 away from 3990, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

In conclusion, the division gives 24861.05649717 with a balance of 2.73e-07.
