We're dividing 83868618 by 42 
We want to divide 83868618 by 42.

Advancing to step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 42

On to step 2:
The number 42 fits into 83 1 times, leaving a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 41 after subtracting 42 from 83.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 42

Let's proceed to step 3:
42 goes into 418 9 times with a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 40 after subtracting 378 from 418.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 42

Going ahead to step 4:
The number 42 fits into 406 9 times, leaving a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 199.0
Subtract 378 from 406 to get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 42

On to step 5:
288 divided by 42 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 1996.0
Subtracting 252 from 288 leaves us with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 42

Moving on to step 6:
When dividing 366 by 42, we get 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 19968.0
Deduct 336 from 366 and we're left with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 42

On to step 7:
If we divide 301 by 42, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 199687.0
Subtract 294 from 301 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 42

Moving on to step 8:
The number 42 fits into 78 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1996871.0
If we take 42 away from 78, we end up 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.

Moving on to step 9:
360 divided by 42 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1996871.8
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:
If we divide 240 by 42, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 1996871.85
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 1996871.857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 1996871.8571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
180 divided by 42 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 1996871.85714
If we subtract 168 from 180, 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.

On to step 14:
120 divided by 42 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 1996871.857142
Deduct 84 from 120 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.

Moving on to step 15:
360 divided by 42 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 1996871.8571428
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.

Going ahead to step 16:
42 goes into 240 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1996871.85714285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 1996871.85714285, with a leftover of 3e-08.
