We're dividing 78169 by 84 
We want to divide 78169 by 84.

On to step 1:
If we divide 7 by 84, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 84

On to step 2:
78 divided by 84 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 84

Step 3:
The number 84 fits into 781 9 times, leaving a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 756 from 781 to get 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 84

On to step 4:
When dividing 256 by 84, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we take 252 away from 256, we end up with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 84

Advancing to step 5:
84 can be fit into 49 0 times, resulting in a remainder of 49.
The next digit of our result is 0. 
Result so far: 930.0
If we take 0 away from 49, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 6:
490 divided by 84 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 930.5
Subtracting 420 from 490 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
84 goes into 700 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 930.58
Subtracting 672 from 700 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
If we divide 280 by 84, we get 3 and a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 930.583
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
84 goes into 280 3 times with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 930.5833
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 930.5833, and the remainder is 0.00028.
