610504 ÷ 81 
Let's see how many times 81 fits into 610504.

Step 1:
81 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 81

Let's proceed to step 2:
81 goes into 61 0 times with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Bring next digit (0) of the dividend behind the 61 and repeat the process: 610 / 81

Advancing to step 3:
81 goes into 610 7 times with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 567 from 610 leaves us with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 81

Let's proceed to step 4:
435 divided by 81 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtracting 405 from 435 leaves us with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 81

Let's proceed to step 5:
The number 81 fits into 300 3 times, leaving a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 753.0
If we take 243 away from 300, we end up with 57.
Include the next digit (4) from the dividend after 57, then repeat: 574 / 81

On to step 6:
574 divided by 81 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7537.0
If we subtract 567 from 574, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 81, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 7537.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
When dividing 700 by 81, we get 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 7537.08
Subtract 648 from 700 to get 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 9:
When dividing 520 by 81, we get 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 7537.086
If we take 486 away from 520, we end up 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 10:
If we divide 340 by 81, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 7537.0864
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
160 divided by 81 is 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 7537.08641
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 12:
81 can be fit into 790 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 7537.086419
Subtracting 729 from 790 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 13:
81 can be fit into 610 7 times, resulting in a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 7537.0864197
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 14:
When dividing 430 by 81, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 7537.08641975
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 7537.08641975 with a remaining 2.5e-08.
