We divide 393780 by 84
Our goal is to divide 393780 by 84.

Advancing to step 1:
3 divided by 84 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 84

Moving on to step 2:
When dividing 39 by 84, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 84

Moving on to step 3:
If we divide 393 by 84, we get 4 and a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 57 after subtracting 336 from 393.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 84

Moving on to step 4:
The number 84 fits into 577 6 times, leaving a remainder of 73.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 504 away from 577, we end up with 73.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 84

Going ahead to step 5:
738 divided by 84 is 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 468.0
The remainder is 66 after subtracting 672 from 738.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 84

Step 6:
84 goes into 660 7 times with a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 4687.0
If we subtract 588 from 660, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
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: 4687.8
If we subtract 672 from 720, we 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.

On to step 8:
84 goes into 480 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 4687.85
Subtracting 420 from 480 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
If we divide 600 by 84, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 4687.857
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.

Moving on to step 10:
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: 4687.8571
Subtract 84 from 120 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.

On to step 11:
360 divided by 84 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 4687.85714
Subtract 336 from 360 to get 24.
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 12:
If we divide 240 by 84, we get 2 and a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 4687.857142
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.

Moving on to step 13:
If we divide 720 by 84, we get 8 and a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 4687.8571428
If we take 672 away from 720, we end up 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 14:
84 goes into 480 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 4687.85714285
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 4687.85714285 and a remainder of 6e-08.
