Let's divide 422085 by 84
We want to divide 422085 by 84.

Advancing to step 1:
4 divided by 84 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 84

Going ahead to step 2:
84 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 84

Advancing to step 3:
When dividing 422 by 84, we get 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 5.0
If we take 420 away from 422, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 84

Let's proceed to step 4:
The number 84 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 84

Advancing to step 5:
84 goes into 208 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 502.0
If we take 168 away from 208, we end up with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 84

On to step 6:
405 divided by 84 is 4 with a remainder of 69.
The next digit of our result is 4. 
Result so far: 5024.0
Deduct 336 from 405 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
If we divide 690 by 84, we get 8 and a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 5024.8
Subtract 672 from 690 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
If we divide 180 by 84, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 5024.82
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
If we divide 120 by 84, we get 1 and a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 5024.821
The remainder is 36 after subtracting 84 from 120.
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 10:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 5024.8214
Deduct 336 from 360 and we're left 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.

Moving on to step 11:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 5024.82142
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
720 divided by 84 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 5024.821428
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.

On to step 13:
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: 5024.8214285
Deduct 420 from 480 and we're left with 60.
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 14:
84 can be fit into 600 7 times, resulting in a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 5024.82142857
Deduct 588 from 600 and we're left 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.

The quotient of the division is 5024.82142857, and the remainder is 1.2e-08.
