We're dividing 1878935 by 90 
We want to divide 1878935 by 90.

Let's proceed to step 1:
1 divided by 90 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 90

Step 2:
The number 90 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 90

Going ahead to step 3:
The number 90 fits into 187 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 180 from 187 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 90

On to step 4:
When dividing 78 by 90, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 78, we end up with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 90

On to step 5:
If we divide 789 by 90, we get 8 and a remainder of 69.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
Deduct 720 from 789 and we're left with 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 90

Advancing to step 6:
90 can be fit into 693 7 times, resulting in a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 2087.0
The remainder is 63 after subtracting 630 from 693.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 90

Advancing to step 7:
90 goes into 635 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 20877.0
The remainder is 5 after subtracting 630 from 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
50 divided by 90 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 20877.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
500 divided by 90 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 20877.05
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 20877.055
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 20877.055 and a remainder of 0.005.
