869091 ÷ 54 
Let's see how many times 54 fits into 869091.

Going ahead to step 1:
54 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 54

Let's proceed to step 2:
86 divided by 54 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 54 from 86 leaves us with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 54

Moving on to step 3:
329 divided by 54 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 324 away from 329, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 54

Advancing to step 4:
54 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Subtracting 0 from 50 leaves us with 50.
Take the next digit (9) from the dividend and append it to 50, then repeat: 509 / 54

Moving on to step 5:
54 goes into 509 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 1609.0
If we subtract 486 from 509, we get 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 54

On to step 6:
54 can be fit into 231 4 times, resulting in a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 16094.0
If we subtract 216 from 231, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
When dividing 150 by 54, we get 2 with a remainder of 42.
The next digit of our result is 2. 
Result so far: 16094.2
Subtracting 108 from 150 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
420 divided by 54 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 16094.27
The remainder is 42 after subtracting 378 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
54 can be fit into 420 7 times, resulting in a remainder of 42.
The next digit of our result is 7. 
Result so far: 16094.277
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 16094.277, and the remainder is 0.0042.
