We look at the division of 42749074 by 84 
Our goal is to divide 42749074 by 84.

Let's proceed to step 1:
84 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 84

Advancing to step 2:
84 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 84

Going ahead to step 3:
427 divided by 84 is 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 7 after subtracting 420 from 427.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 84

Going ahead to step 4:
84 goes into 74 0 times with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 74 and we're left with 74.
Fetch the next digit (9) from the dividend, attach it to 74 and continue: 749 / 84

On to step 5:
84 goes into 749 8 times with a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 508.0
Subtract 672 from 749 to get 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 84

Advancing to step 6:
If we divide 770 by 84, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 5089.0
The remainder is 14 after subtracting 756 from 770.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 84

Advancing to step 7:
The number 84 fits into 147 1 times, leaving a remainder of 63.
The next digit of our result is 1. 
Result so far: 50891.0
If we take 84 away from 147, we end up with 63.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 84

On to step 8:
84 can be fit into 634 7 times, resulting in a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 508917.0
The remainder is 46 after subtracting 588 from 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
84 can be fit into 460 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 508917.5
If we subtract 420 from 460, 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.

Step 10:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 508917.54
The remainder is 64 after subtracting 336 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
When dividing 640 by 84, we get 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 508917.547
The remainder is 52 after subtracting 588 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
520 divided by 84 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 508917.5476
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 84, we get 1 and a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 508917.54761
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
84 can be fit into 760 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 508917.547619
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 15:
40 divided by 84 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 508917.547619
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 16:
If we divide 400 by 84, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 508917.54761904
Subtracting 336 from 400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 508917.54761904 and a remainder of 6.4e-08.
