We look at the division of 23879350 by 840 
Our goal is to divide 23879350 by 840.

Advancing to step 1:
The number 840 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 840

Let's proceed to step 2:
23 divided by 840 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 840

Step 3:
840 can be fit into 238 0 times, resulting in a remainder of 238.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 238, we end up with 238.
Grab the next digit (7) from the dividend, add it to 238, then carry on: 2387 / 840

Let's proceed to step 4:
The number 840 fits into 2387 2 times, leaving a remainder of 707.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1680 from 2387 to get 707.
Append the next digit (9) from the dividend to 707 and continue with: 7079 / 840

Going ahead to step 5:
840 goes into 7079 8 times with a remainder of 359.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 6720 from 7079 to get 359.
Append the next digit (3) from the dividend to 359 and continue with: 3593 / 840

Advancing to step 6:
When dividing 3593 by 840, we get 4 with a remainder of 233.
The number 4 becomes the next digit in our result. 
Result so far: 284.0
Subtracting 3360 from 3593 leaves us with 233.
Append the next digit (5) from the dividend to 233 and continue with: 2335 / 840

Moving on to step 7:
When dividing 2335 by 840, we get 2 with a remainder of 655.
The next digit of our result is 2. 
Result so far: 2842.0
If we subtract 1680 from 2335, we get 655.
Take the next digit (0) from the dividend and append it to 655, then repeat: 6550 / 840

On to step 8:
840 goes into 6550 7 times with a remainder of 670.
Put 7 as the next digit of the answer. 
Result so far: 28427.0
If we subtract 5880 from 6550, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 9:
If we divide 6700 by 840, we get 7 and a remainder of 820.
Write down 7 as next digit of the result. 
Result so far: 28427.7
Subtract 5880 from 6700 to get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 10:
The number 840 fits into 8200 9 times, leaving a remainder of 640.
Use 9 as the next digit of our solution. 
Result so far: 28427.79
The remainder is 640 after subtracting 7560 from 8200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 11:
If we divide 6400 by 840, we get 7 and a remainder of 520.
Use 7 as the next digit of our solution. 
Result so far: 28427.797
The remainder is 520 after subtracting 5880 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 12:
840 goes into 5200 6 times with a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 28427.7976
Subtract 5040 from 5200 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
840 goes into 1600 1 times with a remainder of 760.
Write down 1 as next digit of the result. 
Result so far: 28427.79761
Subtract 840 from 1600 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 14:
If we divide 7600 by 840, we get 9 and a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 28427.797619
If we subtract 7560 from 7600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
840 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 28427.797619
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 16:
4000 divided by 840 is 4 with a remainder of 640.
Use 4 as the next digit of our solution. 
Result so far: 28427.79761904
Deduct 3360 from 4000 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final outcome is 28427.79761904, with a leftover of 6.4e-07.
