We look at the division of 355401 by 84 
We want to divide 355401 by 84.

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
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 84

Advancing to step 2:
84 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 84

Going ahead to step 3:
84 goes into 355 4 times with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 336 from 355, we get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 84

Step 4:
84 goes into 194 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 168 away from 194, we end up with 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 84

Moving on to step 5:
260 divided by 84 is 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 423.0
Subtracting 252 from 260 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 84

Step 6:
The number 84 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 4230.0
Subtract 0 from 81 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 7:
84 can be fit into 810 9 times, resulting in a remainder of 54.
The next digit of our result is 9. 
Result so far: 4230.9
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.

Step 8:
84 can be fit into 540 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 4230.96
Deduct 504 from 540 and we're left 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.

On to step 9:
360 divided by 84 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 4230.964
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
240 divided by 84 is 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 4230.9642
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.

Going ahead to step 11:
If we divide 720 by 84, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 4230.96428
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
If we divide 480 by 84, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 4230.964285
Subtract 420 from 480 to 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 13:
84 can be fit into 600 7 times, resulting in a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 4230.9642857
Subtract 588 from 600 to 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.

On to step 14:
84 goes into 120 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 4230.96428571
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.

In conclusion, the division gives 4230.96428571 with a balance of 3.6e-08.
