We look at the division of 90857646 by 54 
We're looking to find how many times 54 goes into 90857646.

Let's proceed to step 1:
9 divided by 54 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 54

Let's proceed to step 2:
54 can be fit into 90 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 54 from 90 leaves us with 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 54

On to step 3:
The number 54 fits into 368 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 324 away from 368, we end up with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 54

Moving on to step 4:
The number 54 fits into 445 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
The remainder is 13 after subtracting 432 from 445.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 54

Going ahead to step 5:
If we divide 137 by 54, we get 2 and a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 1682.0
If we take 108 away from 137, we end up with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 54

Let's proceed to step 6:
54 goes into 296 5 times with a remainder of 26.
The next digit of our result is 5. 
Result so far: 16825.0
Subtracting 270 from 296 leaves us with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 54

Advancing to step 7:
264 divided by 54 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 168254.0
Subtract 216 from 264 to get 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 54

Advancing to step 8:
If we divide 486 by 54, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 1682549.0
Deduct 486 from 486 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
When dividing 0 by 54, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1682549.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
54 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1682549.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1682549.0, with a leftover of 0.0.
