We're dividing 311539 by 90 
We're looking to find how many times 90 goes into 311539.

Moving on to step 1:
90 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 90

Moving on to step 2:
31 divided by 90 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 90

On to step 3:
When dividing 311 by 90, we get 3 with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 41 after subtracting 270 from 311.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 90

Moving on to step 4:
415 divided by 90 is 4 with a remainder of 55.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Deduct 360 from 415 and we're left with 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 90

Let's proceed to step 5:
553 divided by 90 is 6 with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 346.0
If we subtract 540 from 553, we get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 90

Advancing to step 6:
When dividing 139 by 90, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 3461.0
Deduct 90 from 139 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
The number 90 fits into 490 5 times, leaving a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 3461.5
Subtracting 450 from 490 leaves us 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.

Advancing to step 8:
90 goes into 400 4 times with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 3461.54
Deduct 360 from 400 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.

Going ahead to step 9:
400 divided by 90 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 3461.544
Deduct 360 from 400 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.

The final outcome is 3461.544, with a leftover of 0.004.
