84783 ÷ 42 
We want to figure out the number of times 84783 can be divided by 42.

Advancing to step 1:
42 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 42

Step 2:
84 divided by 42 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 84 from 84.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 42

Moving on to step 3:
If we divide 7 by 42, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 42

Advancing to step 4:
42 goes into 78 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 201.0
Deduct 42 from 78 and we're left with 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 42

Let's proceed to step 5:
When dividing 363 by 42, we get 8 with a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 2018.0
Subtracting 336 from 363 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 6:
The number 42 fits into 270 6 times, leaving a remainder of 18.
The next digit of our result is 6. 
Result so far: 2018.6
If we subtract 252 from 270, we get 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 7:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 2018.64
If we take 168 away from 180, we end up 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 8:
42 goes into 120 2 times with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 2018.642
If we take 84 away from 120, 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:
The number 42 fits into 360 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 2018.6428
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.

Step 10:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2018.64285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
When dividing 300 by 42, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 2018.642857
If we take 294 away from 300, we end up with 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.
Put 1 as the next digit of the answer. 
Result so far: 2018.6428571
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.

Step 13:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 2018.64285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 2018.64285714 with a remainder of 1.2e-08.
