We divide 30921013 by 902
We want to divide 30921013 by 902.

Advancing to step 1:
3 divided by 902 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 902

Moving on to step 2:
902 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 902

Step 3:
309 divided by 902 is 0 with a remainder of 309.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 309, we get 309.
Grab the next digit (2) from the dividend, add it to 309, then carry on: 3092 / 902

Step 4:
When dividing 3092 by 902, we get 3 with a remainder of 386.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2706 from 3092 leaves us with 386.
Include the next digit (1) from the dividend after 386, then repeat: 3861 / 902

Going ahead to step 5:
The number 902 fits into 3861 4 times, leaving a remainder of 253.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 3608 from 3861 and we're left with 253.
Append the next digit (0) from the dividend to 253 and continue with: 2530 / 902

Advancing to step 6:
If we divide 2530 by 902, we get 2 and a remainder of 726.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
Subtract 1804 from 2530 to get 726.
Take the next digit (1) from the dividend and append it to 726, then repeat: 7261 / 902

Step 7:
If we divide 7261 by 902, we get 8 and a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 3428.0
Deduct 7216 from 7261 and we're left with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 902

Let's proceed to step 8:
453 divided by 902 is 0 with a remainder of 453.
Write down 0 as next digit of the result. 
Result so far: 34280.0
Subtract 0 from 453 to get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Let's proceed to step 9:
If we divide 4530 by 902, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 34280.5
If we subtract 4510 from 4530, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
902 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 34280.5
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
902 can be fit into 2000 2 times, resulting in a remainder of 196.
Record the quotient 2 as the next digit in the result. 
Result so far: 34280.502
Subtract 1804 from 2000 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 12:
If we divide 1960 by 902, we get 2 and a remainder of 156.
Record the quotient 2 as the next digit in the result. 
Result so far: 34280.5022
Subtract 1804 from 1960 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

After the division, we end up with 34280.5022 and a remainder of 0.00156.
