362121 ÷ 84 
We want to divide 362121 by 84.

Advancing to step 1:
3 divided by 84 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 84

On to step 2:
If we divide 36 by 84, we get 0 and a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 84

Let's proceed to step 3:
362 divided by 84 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 336 from 362 to get 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 84

Going ahead to step 4:
When dividing 261 by 84, we get 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 252 from 261 to get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 84

Let's proceed to step 5:
92 divided by 84 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 431.0
The remainder is 8 after subtracting 84 from 92.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 84

Moving on to step 6:
The number 84 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 4310.0
Deduct 0 from 81 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 7:
810 divided by 84 is 9 with a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 4310.9
The remainder is 54 after subtracting 756 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
When dividing 540 by 84, we get 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 4310.96
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
84 goes into 360 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4310.964
If we take 336 away from 360, we end up 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.

On to step 10:
84 can be fit into 240 2 times, resulting in a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 4310.9642
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
84 can be fit into 720 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 4310.96428
Deduct 672 from 720 and we're left 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.

Step 12:
84 goes into 480 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 4310.964285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 4310.9642857
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 84, we get 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 4310.96428571
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 4310.96428571, with a leftover of 3.6e-08.
