53658 divided by 81 
We're looking to find how many times 81 goes into 53658.

Going ahead to step 1:
When dividing 5 by 81, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 81

Step 2:
When dividing 53 by 81, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Take the next digit (6) from the dividend and append it to 53, then repeat: 536 / 81

Advancing to step 3:
The number 81 fits into 536 6 times, leaving a remainder of 50.
The next digit of our result is 6. 
Result so far: 6.0
If we take 486 away from 536, we end up with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 81

Step 4:
81 can be fit into 505 6 times, resulting in a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtract 486 from 505 to get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 81

Step 5:
81 goes into 198 2 times with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 662.0
Deduct 162 from 198 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 6:
If we divide 360 by 81, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 662.4
The remainder is 36 after subtracting 324 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
81 can be fit into 360 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 662.44
Deduct 324 from 360 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 662.44 with a remaining 0.036.
