We're dividing 406990 by 84 
We're looking to find how many times 84 goes into 406990.

Let's proceed to step 1:
84 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 84

On to step 2:
The number 84 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 84

Advancing to step 3:
If we divide 406 by 84, we get 4 and a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 336 from 406 and we're left with 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 84

Let's proceed to step 4:
The number 84 fits into 709 8 times, leaving a remainder of 37.
The next digit of our result is 8. 
Result so far: 48.0
If we subtract 672 from 709, we get 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 84

Let's proceed to step 5:
84 can be fit into 379 4 times, resulting in a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 484.0
Subtract 336 from 379 to get 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 84

Let's proceed to step 6:
430 divided by 84 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 4845.0
Subtract 420 from 430 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
84 goes into 100 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 4845.1
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
When dividing 160 by 84, we get 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 4845.11
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 4845.11 and a remainder of 0.076.
