901289 ÷ 54 
Let's see how many times 54 fits into 901289.

Step 1:
The number 54 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 54

Let's proceed to step 2:
54 goes into 90 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 54 from 90 to get 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 54

Advancing to step 3:
When dividing 361 by 54, we get 6 with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 324 away from 361, we end up with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 54

Step 4:
The number 54 fits into 372 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
Subtracting 324 from 372 leaves us with 48.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 54

Advancing to step 5:
When dividing 488 by 54, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 1669.0
The remainder is 2 after subtracting 486 from 488.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 54

Advancing to step 6:
29 divided by 54 is 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 16690.0
Deduct 0 from 29 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
If we divide 290 by 54, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 16690.5
If we take 270 away from 290, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 54, we get 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 16690.53
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
54 can be fit into 380 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 16690.537
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 54 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 16690.537
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
If we divide 200 by 54, we get 3 and a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 16690.53703
Deduct 162 from 200 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
54 can be fit into 380 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 16690.537037
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
When dividing 20 by 54, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 16690.537037
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
200 divided by 54 is 3 with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 16690.53703703
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 16690.53703703, with a leftover of 3.8e-08.
