Let's divide 57550136 by 90
We want to divide 57550136 by 90.

Moving on to step 1:
When dividing 5 by 90, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 90

Advancing to step 2:
90 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 90

Advancing to step 3:
90 goes into 575 6 times with a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 540 from 575 leaves us with 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 90

Let's proceed to step 4:
If we divide 355 by 90, we get 3 and a remainder of 85.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we take 270 away from 355, we end up with 85.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 90

Let's proceed to step 5:
The number 90 fits into 850 9 times, leaving a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 639.0
If we take 810 away from 850, we end up with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 90

Let's proceed to step 6:
401 divided by 90 is 4 with a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 6394.0
Subtracting 360 from 401 leaves us with 41.
Fetch the next digit (3) from the dividend, attach it to 41 and continue: 413 / 90

Moving on to step 7:
The number 90 fits into 413 4 times, leaving a remainder of 53.
The next digit of our result is 4. 
Result so far: 63944.0
If we subtract 360 from 413, we get 53.
Take the next digit (6) from the dividend and append it to 53, then repeat: 536 / 90

Advancing to step 8:
If we divide 536 by 90, we get 5 and a remainder of 86.
The number 5 becomes the next digit in our result. 
Result so far: 639445.0
If we subtract 450 from 536, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 9:
860 divided by 90 is 9 with a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 639445.9
If we subtract 810 from 860, 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 10:
90 goes into 500 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 639445.95
Subtract 450 from 500 to 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.

Going ahead to step 11:
90 can be fit into 500 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 639445.955
Subtracting 450 from 500 leaves us 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.

Our division results in 639445.955 with a remaining 0.005.
