Let's divide 58810668 by 90
We're looking to find how many times 90 goes into 58810668.

Moving on to step 1:
5 divided by 90 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 90

On to step 2:
90 goes into 58 0 times with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 90

Step 3:
90 goes into 588 6 times with a remainder of 48.
The next digit of our result is 6. 
Result so far: 6.0
If we take 540 away from 588, we end up with 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 90

Advancing to step 4:
If we divide 481 by 90, we get 5 and a remainder of 31.
The next digit of our result is 5. 
Result so far: 65.0
Deduct 450 from 481 and we're left with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 90

Going ahead to step 5:
The number 90 fits into 310 3 times, leaving a remainder of 40.
The next digit of our result is 3. 
Result so far: 653.0
The remainder is 40 after subtracting 270 from 310.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 90

Moving on to step 6:
406 divided by 90 is 4 with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 6534.0
The remainder is 46 after subtracting 360 from 406.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 90

Let's proceed to step 7:
90 can be fit into 466 5 times, resulting in a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 65345.0
If we subtract 450 from 466, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 90

On to step 8:
90 can be fit into 168 1 times, resulting in a remainder of 78.
The next digit of our result is 1. 
Result so far: 653451.0
If we subtract 90 from 168, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 9:
If we divide 780 by 90, we get 8 and a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 653451.8
If we subtract 720 from 780, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
When dividing 600 by 90, we get 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 653451.86
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
600 divided by 90 is 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 653451.866
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 653451.866 with a remainder of 0.006.
