We're dividing 55381 by 86 
We want to divide 55381 by 86.

Moving on to step 1:
If we divide 5 by 86, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 86

Advancing to step 2:
When dividing 55 by 86, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 86

Moving on to step 3:
When dividing 553 by 86, we get 6 with a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 37 after subtracting 516 from 553.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 86

On to step 4:
86 goes into 378 4 times with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 344 from 378, we get 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 86

Advancing to step 5:
341 divided by 86 is 3 with a remainder of 83.
The next digit of our result is 3. 
Result so far: 643.0
Subtracting 258 from 341 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 6:
830 divided by 86 is 9 with a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 643.9
If we subtract 774 from 830, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
If we divide 560 by 86, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 643.96
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
440 divided by 86 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 643.965
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
86 can be fit into 100 1 times, resulting in a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 643.9651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
When dividing 140 by 86, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 643.96511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 643.96511 and a remainder of 5.4e-05.
