68418669 ÷ 531 
We want to divide 68418669 by 531.

Going ahead to step 1:
If we divide 6 by 531, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 531

Let's proceed to step 2:
When dividing 68 by 531, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 531

Step 3:
The number 531 fits into 684 1 times, leaving a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 531 from 684 leaves us with 153.
Fetch the next digit (1) from the dividend, attach it to 153 and continue: 1531 / 531

Let's proceed to step 4:
If we divide 1531 by 531, we get 2 and a remainder of 469.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1062 from 1531 leaves us with 469.
Include the next digit (8) from the dividend after 469, then repeat: 4698 / 531

Advancing to step 5:
If we divide 4698 by 531, we get 8 and a remainder of 450.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtract 4248 from 4698 to get 450.
Fetch the next digit (6) from the dividend, attach it to 450 and continue: 4506 / 531

Advancing to step 6:
4506 divided by 531 is 8 with a remainder of 258.
Record the quotient 8 as the next digit in the result. 
Result so far: 1288.0
Subtract 4248 from 4506 to get 258.
Bring next digit (6) of the dividend behind the 258 and repeat the process: 2586 / 531

Going ahead to step 7:
The number 531 fits into 2586 4 times, leaving a remainder of 462.
Record the quotient 4 as the next digit in the result. 
Result so far: 12884.0
If we take 2124 away from 2586, we end up with 462.
Grab the next digit (9) from the dividend, add it to 462, then carry on: 4629 / 531

Step 8:
531 goes into 4629 8 times with a remainder of 381.
The next digit of our result is 8. 
Result so far: 128848.0
If we subtract 4248 from 4629, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

On to step 9:
3810 divided by 531 is 7 with a remainder of 93.
The next digit of our result is 7. 
Result so far: 128848.7
Subtracting 3717 from 3810 leaves us 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.

Moving on to step 10:
The number 531 fits into 930 1 times, leaving a remainder of 399.
The number 1 becomes the next digit in our result. 
Result so far: 128848.71
Deduct 531 from 930 and we're left 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 11:
If we divide 3990 by 531, we get 7 and a remainder of 273.
Put 7 as the next digit of the answer. 
Result so far: 128848.717
The remainder is 273 after subtracting 3717 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Going ahead to step 12:
531 can be fit into 2730 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 128848.7175
Subtracting 2655 from 2730 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 13:
531 goes into 750 1 times with a remainder of 219.
Record the quotient 1 as the next digit in the result. 
Result so far: 128848.71751
Subtract 531 from 750 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 14:
When dividing 2190 by 531, we get 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 128848.717514
The remainder is 66 after subtracting 2124 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 15:
When dividing 660 by 531, we get 1 with a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 128848.7175141
If we take 531 away from 660, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 16:
531 goes into 1290 2 times with a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 128848.71751412
Subtract 1062 from 1290 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The final result is 128848.71751412 with a remainder of 2.28e-07.
