Let's divide 68726309 by 431
We want to divide 68726309 by 431.

Let's proceed to step 1:
If we divide 6 by 431, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 431

Step 2:
68 divided by 431 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Include the next digit (7) from the dividend after 68, then repeat: 687 / 431

Going ahead to step 3:
If we divide 687 by 431, we get 1 and a remainder of 256.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 431 from 687 to get 256.
Append the next digit (2) from the dividend to 256 and continue with: 2562 / 431

Advancing to step 4:
The number 431 fits into 2562 5 times, leaving a remainder of 407.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 2155 from 2562 leaves us with 407.
Bring next digit (6) of the dividend behind the 407 and repeat the process: 4076 / 431

On to step 5:
4076 divided by 431 is 9 with a remainder of 197.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
The remainder is 197 after subtracting 3879 from 4076.
Take the next digit (3) from the dividend and append it to 197, then repeat: 1973 / 431

Let's proceed to step 6:
When dividing 1973 by 431, we get 4 with a remainder of 249.
Record the quotient 4 as the next digit in the result. 
Result so far: 1594.0
If we take 1724 away from 1973, we end up with 249.
Take the next digit (0) from the dividend and append it to 249, then repeat: 2490 / 431

Going ahead to step 7:
431 can be fit into 2490 5 times, resulting in a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 15945.0
Subtract 2155 from 2490 to get 335.
Append the next digit (9) from the dividend to 335 and continue with: 3359 / 431

Moving on to step 8:
3359 divided by 431 is 7 with a remainder of 342.
Record the quotient 7 as the next digit in the result. 
Result so far: 159457.0
The remainder is 342 after subtracting 3017 from 3359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 9:
3420 divided by 431 is 7 with a remainder of 403.
Put 7 as the next digit of the answer. 
Result so far: 159457.7
Deduct 3017 from 3420 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Going ahead to step 10:
431 can be fit into 4030 9 times, resulting in a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 159457.79
Subtract 3879 from 4030 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 11:
1510 divided by 431 is 3 with a remainder of 217.
The next digit of our result is 3. 
Result so far: 159457.793
Subtract 1293 from 1510 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 12:
431 goes into 2170 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 159457.7935
The remainder is 15 after subtracting 2155 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
The number 431 fits into 150 0 times, leaving a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 159457.7935
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
The number 431 fits into 1500 3 times, leaving a remainder of 207.
Record the quotient 3 as the next digit in the result. 
Result so far: 159457.793503
Deduct 1293 from 1500 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 15:
431 can be fit into 2070 4 times, resulting in a remainder of 346.
The number 4 becomes the next digit in our result. 
Result so far: 159457.7935034
Subtract 1724 from 2070 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 16:
431 goes into 3460 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 159457.79350348
Subtract 3448 from 3460 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 159457.79350348 with a remaining 1.2e-08.
