We look at the division of 5012378 by 90 
Our goal is to divide 5012378 by 90.

Advancing to step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 90

Going ahead to step 2:
90 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 90

Advancing to step 3:
When dividing 501 by 90, we get 5 with a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 450 from 501 to get 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 90

Advancing to step 4:
When dividing 512 by 90, we get 5 with a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 55.0
Deduct 450 from 512 and we're left with 62.
Fetch the next digit (3) from the dividend, attach it to 62 and continue: 623 / 90

On to step 5:
90 can be fit into 623 6 times, resulting in a remainder of 83.
Write down 6 as next digit of the result. 
Result so far: 556.0
Subtracting 540 from 623 leaves us with 83.
Grab the next digit (7) from the dividend, add it to 83, then carry on: 837 / 90

Moving on to step 6:
The number 90 fits into 837 9 times, leaving a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 5569.0
Subtract 810 from 837 to get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 90

Step 7:
The number 90 fits into 278 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 55693.0
The remainder is 8 after subtracting 270 from 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
90 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 55693.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
90 goes into 800 8 times with a remainder of 80.
The next digit of our result is 8. 
Result so far: 55693.08
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
800 divided by 90 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 55693.088
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 55693.088 with a remaining 0.008.
