Let's divide 869857 by 54
We're looking to find how many times 54 goes into 869857.

Going ahead to step 1:
The number 54 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 54

Going ahead to step 2:
54 can be fit into 86 1 times, resulting in a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 54 from 86 to get 32.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 54

Advancing to step 3:
The number 54 fits into 329 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 324 from 329, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 54

Advancing to step 4:
54 goes into 58 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 161.0
If we subtract 54 from 58, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 54

Let's proceed to step 5:
54 goes into 45 0 times with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 1610.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 54

Let's proceed to step 6:
When dividing 457 by 54, we get 8 with a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 16108.0
If we subtract 432 from 457, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
When dividing 250 by 54, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 16108.4
Deduct 216 from 250 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
340 divided by 54 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 16108.46
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
The number 54 fits into 160 2 times, leaving a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 16108.462
Deduct 108 from 160 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
If we divide 520 by 54, we get 9 and a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 16108.4629
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
If we divide 340 by 54, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 16108.46296
If we take 324 away from 340, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
54 goes into 160 2 times with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 16108.462962
If we take 108 away from 160, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
520 divided by 54 is 9 with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 16108.4629629
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
340 divided by 54 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 16108.46296296
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 16108.46296296 with a remainder of 1.6e-08.
