We divide 90508333 by 387
We want to figure out the number of times 90508333 can be divided by 387.

Advancing to step 1:
9 divided by 387 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 387

Advancing to step 2:
387 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 387

On to step 3:
If we divide 905 by 387, we get 2 and a remainder of 131.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 774 from 905 to get 131.
Bring next digit (0) of the dividend behind the 131 and repeat the process: 1310 / 387

Let's proceed to step 4:
1310 divided by 387 is 3 with a remainder of 149.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 1161 from 1310 leaves us with 149.
Append the next digit (8) from the dividend to 149 and continue with: 1498 / 387

On to step 5:
387 can be fit into 1498 3 times, resulting in a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 233.0
If we subtract 1161 from 1498, we get 337.
Grab the next digit (3) from the dividend, add it to 337, then carry on: 3373 / 387

On to step 6:
387 goes into 3373 8 times with a remainder of 277.
Write down 8 as next digit of the result. 
Result so far: 2338.0
Subtract 3096 from 3373 to get 277.
Include the next digit (3) from the dividend after 277, then repeat: 2773 / 387

Let's proceed to step 7:
If we divide 2773 by 387, we get 7 and a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 23387.0
Subtract 2709 from 2773 to get 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 387

Going ahead to step 8:
387 goes into 643 1 times with a remainder of 256.
Use 1 as the next digit of our solution. 
Result so far: 233871.0
Subtracting 387 from 643 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 9:
If we divide 2560 by 387, we get 6 and a remainder of 238.
The number 6 becomes the next digit in our result. 
Result so far: 233871.6
Subtract 2322 from 2560 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 10:
The number 387 fits into 2380 6 times, leaving a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 233871.66
If we take 2322 away from 2380, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 233871.66, with a leftover of 0.058.
