121346 ÷ 84 
Our goal is to divide 121346 by 84.

Going ahead to step 1:
1 divided by 84 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 84

Moving on to step 2:
12 divided by 84 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 84

Moving on to step 3:
The number 84 fits into 121 1 times, leaving a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 37 after subtracting 84 from 121.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 84

Let's proceed to step 4:
The number 84 fits into 373 4 times, leaving a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 336 away from 373, we end up with 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 84

Step 5:
84 goes into 374 4 times with a remainder of 38.
The next digit of our result is 4. 
Result so far: 144.0
Deduct 336 from 374 and we're left with 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 84

Advancing to step 6:
The number 84 fits into 386 4 times, leaving a remainder of 50.
The next digit of our result is 4. 
Result so far: 1444.0
If we subtract 336 from 386, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
When dividing 500 by 84, we get 5 with a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 1444.5
If we subtract 420 from 500, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 1444.59
Subtracting 756 from 800 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
440 divided by 84 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1444.595
Deduct 420 from 440 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 1444.5952
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
If we divide 320 by 84, we get 3 and a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 1444.59523
If we subtract 252 from 320, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 12:
The number 84 fits into 680 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 1444.595238
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 1444.595238
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
84 goes into 800 9 times with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 1444.59523809
Subtracting 756 from 800 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 1444.59523809 and a remainder of 4.4e-08.
