We divide 8440805 by 84
We want to figure out the number of times 8440805 can be divided by 84.

On to step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 84

On to step 2:
84 divided by 84 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 84 from 84.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 84

On to step 3:
84 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 84

On to step 4:
84 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we subtract 0 from 40, we get 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 84

Going ahead to step 5:
When dividing 408 by 84, we get 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 1004.0
If we take 336 away from 408, we end up with 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 84

Let's proceed to step 6:
If we divide 720 by 84, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 10048.0
Subtract 672 from 720 to get 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 84

Moving on to step 7:
The number 84 fits into 485 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 100485.0
Subtracting 420 from 485 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 8:
When dividing 650 by 84, we get 7 with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 100485.7
The remainder is 62 after subtracting 588 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
When dividing 620 by 84, we get 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 100485.77
Subtracting 588 from 620 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 100485.77 with a remainder of 0.032.
