We're dividing 121882 by 84 
Our goal is to divide 121882 by 84.

Going ahead to step 1:
When dividing 1 by 84, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 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.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 84

Moving on to step 3:
84 can be fit into 121 1 times, resulting in a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 37 after subtracting 84 from 121.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 84

On to step 4:
If we divide 378 by 84, we get 4 and a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 42 after subtracting 336 from 378.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 84

Let's proceed to step 5:
84 goes into 428 5 times with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 145.0
If we take 420 away from 428, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 84

On to step 6:
If we divide 82 by 84, we get 0 and a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 1450.0
If we subtract 0 from 82, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 7:
When dividing 820 by 84, we get 9 with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 1450.9
Deduct 756 from 820 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
640 divided by 84 is 7 with a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 1450.97
The remainder is 52 after subtracting 588 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
84 goes into 520 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 1450.976
Subtracting 504 from 520 leaves us 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.

Going ahead to step 10:
84 can be fit into 160 1 times, resulting in a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 1450.9761
Subtracting 84 from 160 leaves us 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.

On to step 11:
84 can be fit into 760 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 1450.97619
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
The number 84 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1450.97619
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
When dividing 400 by 84, we get 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 1450.9761904
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
If we divide 640 by 84, we get 7 and a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 1450.97619047
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 1450.97619047, with a leftover of 5.2e-08.
