We're dividing 840178 by 84 
We're looking to find how many times 84 goes into 840178.

Let's proceed to step 1:
If we divide 8 by 84, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 84

Advancing to step 2:
84 divided by 84 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 84 from 84, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 84

Moving on to step 3:
The number 84 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 84

Advancing to step 4:
If we divide 1 by 84, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 84

On to step 5:
The number 84 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 1000.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 84

On to step 6:
178 divided by 84 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 10002.0
If we subtract 168 from 178, we 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.

Let's proceed to step 7:
100 divided by 84 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 10002.1
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
160 divided by 84 is 1 with a remainder of 76.
The next digit of our result is 1. 
Result so far: 10002.11
Deduct 84 from 160 and we're left 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 10002.11 and a remainder of 0.076.
