We're dividing 42105236 by 83 
We want to figure out the number of times 42105236 can be divided by 83.

Step 1:
83 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 83

On to step 2:
42 divided by 83 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 83

Step 3:
83 can be fit into 421 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 415 from 421 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 83

Step 4:
The number 83 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Deduct 0 from 60 and we're left with 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 83

Step 5:
83 goes into 605 7 times with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 507.0
Subtract 581 from 605 to get 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 83

On to step 6:
242 divided by 83 is 2 with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 5072.0
Deduct 166 from 242 and we're left with 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 83

Let's proceed to step 7:
83 can be fit into 763 9 times, resulting in a remainder of 16.
The next digit of our result is 9. 
Result so far: 50729.0
If we subtract 747 from 763, we get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 83

Advancing to step 8:
The number 83 fits into 166 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 507292.0
Subtracting 166 from 166 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 83, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 507292.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 83, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 507292.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 507292.0 and a remainder of 0.0.
