We look at the division of 100030 by 84 
Our goal is to divide 100030 by 84.

Let's proceed to step 1:
If we divide 1 by 84, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 84

Advancing to step 2:
10 divided by 84 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 84

On to step 3:
If we divide 100 by 84, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 84 from 100 and we're left with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 84

Moving on to step 4:
160 divided by 84 is 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 84 from 160 and we're left with 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 84

Moving on to step 5:
If we divide 763 by 84, we get 9 and a remainder of 7.
The next digit of our result is 9. 
Result so far: 119.0
The remainder is 7 after subtracting 756 from 763.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 84

On to step 6:
70 divided by 84 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 1190.0
Deduct 0 from 70 and we're left 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.

Going ahead to step 7:
84 goes into 700 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 1190.8
Subtract 672 from 700 to get 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:
When dividing 280 by 84, we get 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 1190.83
If we take 252 away from 280, we end up 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.

Step 9:
The number 84 fits into 280 3 times, leaving a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 1190.833
Deduct 252 from 280 and we're left 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.

The final result is 1190.833 with a remainder of 0.0028.
