We divide 409386 by 84
We want to figure out the number of times 409386 can be divided by 84.

Advancing to step 1:
If we divide 4 by 84, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 84

On to step 2:
84 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 84

Advancing to step 3:
84 goes into 409 4 times with a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 336 from 409 and we're left with 73.
Append the next digit (3) from the dividend to 73 and continue with: 733 / 84

Going ahead to step 4:
The number 84 fits into 733 8 times, leaving a remainder of 61.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 61 after subtracting 672 from 733.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 84

Advancing to step 5:
If we divide 618 by 84, we get 7 and a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 487.0
If we subtract 588 from 618, we get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 84

Going ahead to step 6:
84 can be fit into 306 3 times, resulting in a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 4873.0
Subtracting 252 from 306 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
The number 84 fits into 540 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 4873.6
If we subtract 504 from 540, we 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.

Advancing to step 8:
When dividing 360 by 84, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 4873.64
Subtract 336 from 360 to get 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 9:
240 divided by 84 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 4873.642
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
84 can be fit into 720 8 times, resulting in a remainder of 48.
The next digit of our result is 8. 
Result so far: 4873.6428
Subtract 672 from 720 to 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.

Going ahead to step 11:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 4873.64285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
The number 84 fits into 600 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 4873.642857
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
If we divide 120 by 84, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 4873.6428571
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.

Advancing to step 14:
When dividing 360 by 84, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4873.64285714
If we take 336 away from 360, we end up 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.

After the division, we end up with 4873.64285714 and a remainder of 2.4e-08.
