We're dividing 103155 by 84 
We want to divide 103155 by 84.

Step 1:
If we divide 1 by 84, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 84

Moving on to step 2:
The number 84 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 84

Let's proceed to step 3:
When dividing 103 by 84, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 84 from 103 leaves us with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 84

Going ahead to step 4:
84 goes into 191 2 times with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 168 from 191 to get 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 84

Let's proceed to step 5:
235 divided by 84 is 2 with a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtracting 168 from 235 leaves us with 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 84

Going ahead to step 6:
When dividing 675 by 84, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 1228.0
Deduct 672 from 675 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
84 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1228.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 84 fits into 300 3 times, leaving a remainder of 48.
The next digit of our result is 3. 
Result so far: 1228.03
Subtracting 252 from 300 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
When dividing 480 by 84, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 1228.035
If we subtract 420 from 480, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
If we divide 600 by 84, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 1228.0357
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.

Advancing to step 11:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1228.03571
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
When dividing 360 by 84, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 1228.035714
Subtracting 336 from 360 leaves us 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 13:
If we divide 240 by 84, we get 2 and a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 1228.0357142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
If we divide 720 by 84, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1228.03571428
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.

The quotient of the division is 1228.03571428, and the remainder is 4.8e-08.
