290391 divided by 84 
Our goal is to divide 290391 by 84.

Advancing to step 1:
If we divide 2 by 84, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 84

Moving on to step 2:
29 divided by 84 is 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 84

Let's proceed to step 3:
84 goes into 290 3 times with a remainder of 38.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 38 after subtracting 252 from 290.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 84

Step 4:
If we divide 383 by 84, we get 4 and a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 34.0
Deduct 336 from 383 and we're left with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 84

Moving on to step 5:
If we divide 479 by 84, we get 5 and a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 345.0
Subtract 420 from 479 to get 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 84

Going ahead to step 6:
When dividing 591 by 84, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 3457.0
The remainder is 3 after subtracting 588 from 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 84 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3457.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 84 fits into 300 3 times, leaving a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 3457.03
Subtracting 252 from 300 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
84 goes into 480 5 times with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 3457.035
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
If we divide 600 by 84, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 3457.0357
If we take 588 away from 600, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
120 divided by 84 is 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 3457.03571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
If we divide 360 by 84, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 3457.035714
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
240 divided by 84 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 3457.0357142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
84 goes into 720 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 3457.03571428
If we subtract 672 from 720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 3457.03571428, with a leftover of 4.8e-08.
