353840 divided by 84 
Our goal is to divide 353840 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
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 84

Going ahead to step 2:
35 divided by 84 is 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 84

Going ahead to step 3:
If we divide 353 by 84, we get 4 and a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 336 away from 353, we end up with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 84

Step 4:
If we divide 178 by 84, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 10 after subtracting 168 from 178.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 84

Advancing to step 5:
If we divide 104 by 84, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 421.0
The remainder is 20 after subtracting 84 from 104.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 84

Step 6:
84 goes into 200 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 4212.0

84 can be fit into 680 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 4212.38
Deduct 672 from 680 and we're left 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.

Moving on to step 9:
The number 84 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 4212.38
The remainder is 80 after subtracting 0 from 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 10:
If we divide 800 by 84, we get 9 and a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 4212.3809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
The number 84 fits into 440 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 4212.38095
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.

Step 12:
84 goes into 200 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 4212.380952
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
The number 84 fits into 320 3 times, leaving a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 4212.3809523
Subtracting 252 from 320 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
680 divided by 84 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 4212.38095238
Deduct 672 from 680 and we're left 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.

The quotient of the division is 4212.38095238, and the remainder is 8e-09.
