Let's divide 30900863 by 84
Let's see how many times 84 fits into 30900863.

Let's proceed to step 1:
If we divide 3 by 84, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our 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 / 84

Moving on to step 2:
The number 84 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 84

Advancing to step 3:
309 divided by 84 is 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 252 from 309 leaves us with 57.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 84

On to step 4:
570 divided by 84 is 6 with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 36.0
Deduct 504 from 570 and we're left with 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 84

Step 5:
The number 84 fits into 660 7 times, leaving a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 367.0
Subtract 588 from 660 to get 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 84

Step 6:
When dividing 728 by 84, we get 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 3678.0
Deduct 672 from 728 and we're left with 56.
Take the next digit (6) from the dividend and append it to 56, then repeat: 566 / 84

Let's proceed to step 7:
If we divide 566 by 84, we get 6 and a remainder of 62.
The next digit of our result is 6. 
Result so far: 36786.0
Subtracting 504 from 566 leaves us with 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 84

On to step 8:
When dividing 623 by 84, we get 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 367867.0
Subtract 588 from 623 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
350 divided by 84 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 367867.4
Subtract 336 from 350 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
140 divided by 84 is 1 with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 367867.41
If we subtract 84 from 140, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
560 divided by 84 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 367867.416
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
If we divide 560 by 84, we get 6 and a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 367867.4166
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 367867.4166 with a remainder of 0.00056.
