We divide 31913952 by 321
Our goal is to divide 31913952 by 321.

Moving on to step 1:
3 divided by 321 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 321

Let's proceed to step 2:
321 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 321

Step 3:
When dividing 319 by 321, we get 0 with a remainder of 319.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 319, we get 319.
Append the next digit (1) from the dividend to 319 and continue with: 3191 / 321

Moving on to step 4:
When dividing 3191 by 321, we get 9 with a remainder of 302.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 2889 away from 3191, we end up with 302.
Fetch the next digit (3) from the dividend, attach it to 302 and continue: 3023 / 321

Moving on to step 5:
When dividing 3023 by 321, we get 9 with a remainder of 134.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtract 2889 from 3023 to get 134.
Take the next digit (9) from the dividend and append it to 134, then repeat: 1349 / 321

Let's proceed to step 6:
If we divide 1349 by 321, we get 4 and a remainder of 65.
Record the quotient 4 as the next digit in the result. 
Result so far: 994.0
If we subtract 1284 from 1349, we get 65.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 321

Advancing to step 7:
When dividing 655 by 321, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 9942.0
If we subtract 642 from 655, we get 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 321

Let's proceed to step 8:
The number 321 fits into 132 0 times, leaving a remainder of 132.
Write down 0 as next digit of the result. 
Result so far: 99420.0
Deduct 0 from 132 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 9:
When dividing 1320 by 321, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 99420.4
The remainder is 36 after subtracting 1284 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
When dividing 360 by 321, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 99420.41
If we take 321 away from 360, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 11:
390 divided by 321 is 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 99420.411
If we subtract 321 from 390, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final result is 99420.411 with a remainder of 0.0069.
