We divide 42489190 by 84
We're looking to find how many times 84 goes into 42489190.

On to step 1:
84 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 84

Moving on to step 2:
42 divided by 84 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 84

Going ahead to step 3:
424 divided by 84 is 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 4 after subtracting 420 from 424.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 84

Going ahead to step 4:
84 goes into 48 0 times with a remainder of 48.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 48, we get 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 84

Going ahead to step 5:
84 goes into 489 5 times with a remainder of 69.
Record the quotient 5 as the next digit in the result. 
Result so far: 505.0
Subtract 420 from 489 to get 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 84

Let's proceed to step 6:
When dividing 691 by 84, we get 8 with a remainder of 19.
The next digit of our result is 8. 
Result so far: 5058.0
Subtract 672 from 691 to get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 84

Going ahead to step 7:
If we divide 199 by 84, we get 2 and a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 50582.0
If we take 168 away from 199, we end up with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 84

Step 8:
84 can be fit into 310 3 times, resulting in a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 505823.0
Deduct 252 from 310 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
580 divided by 84 is 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 505823.6
If we subtract 504 from 580, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
84 can be fit into 760 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 505823.69
Deduct 756 from 760 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
The number 84 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 505823.69
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
84 goes into 400 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 505823.6904
If we take 336 away from 400, we end up 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.

Moving on to step 13:
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: 505823.69047
Subtracting 588 from 640 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
84 goes into 520 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 505823.690476
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 15:
If we divide 160 by 84, we get 1 and a remainder of 76.
The next digit of our result is 1. 
Result so far: 505823.6904761
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 16:
When dividing 760 by 84, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 505823.69047619
If we take 756 away from 760, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 505823.69047619 with a remainder of 4e-09.
