We look at the division of 861880 by 54 
We want to divide 861880 by 54.

Let's proceed to step 1:
8 divided by 54 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 54

Moving on to step 2:
When dividing 86 by 54, we get 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 54 away from 86, we end up with 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 54

On to step 3:
If we divide 321 by 54, we get 5 and a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 270 from 321 to get 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 54

Advancing to step 4:
The number 54 fits into 518 9 times, leaving a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 159.0
The remainder is 32 after subtracting 486 from 518.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 54

Moving on to step 5:
When dividing 328 by 54, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1596.0
Deduct 324 from 328 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 54

Moving on to step 6:
54 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 15960.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
54 can be fit into 400 7 times, resulting in a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 15960.7
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
220 divided by 54 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 15960.74
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 54, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 15960.74
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
400 divided by 54 is 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 15960.7407
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
When dividing 220 by 54, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 15960.74074
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
54 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 15960.74074
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
If we divide 400 by 54, we get 7 and a remainder of 22.
The next digit of our result is 7. 
Result so far: 15960.7407407
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
54 can be fit into 220 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 15960.74074074
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 15960.74074074 with a remainder of 4e-09.
