642782 divided by 90 
We want to figure out the number of times 642782 can be divided by 90.

Let's proceed to step 1:
When dividing 6 by 90, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 90

Moving on to step 2:
The number 90 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 90

Step 3:
When dividing 642 by 90, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 630 from 642 and we're left with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 90

Step 4:
The number 90 fits into 127 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 90 from 127, we get 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 90

Advancing to step 5:
90 can be fit into 378 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 714.0
Subtract 360 from 378 to get 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 90

Moving on to step 6:
If we divide 182 by 90, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 7142.0
If we subtract 180 from 182, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
90 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7142.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 7142.02
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 90 fits into 200 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 7142.022
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 7142.022 with a balance of 0.002.
