Let's divide 902869 by 81
We're looking to find how many times 81 goes into 902869.

Moving on to step 1:
9 divided by 81 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 81

Advancing to step 2:
If we divide 90 by 81, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 81 from 90 to get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 81

Let's proceed to step 3:
81 can be fit into 92 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 81 from 92, we get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 81

Advancing to step 4:
If we divide 118 by 81, we get 1 and a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 111.0
Subtract 81 from 118 to get 37.
Take the next digit (6) from the dividend and append it to 37, then repeat: 376 / 81

Let's proceed to step 5:
81 goes into 376 4 times with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 1114.0
If we take 324 away from 376, we end up with 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 81

On to step 6:
81 goes into 529 6 times with a remainder of 43.
The next digit of our result is 6. 
Result so far: 11146.0
Subtracting 486 from 529 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.

Moving on to step 7:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 11146.5
If we subtract 405 from 430, 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.

Let's proceed to step 8:
If we divide 250 by 81, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 11146.53
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
The number 81 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 11146.53
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 10:
81 can be fit into 700 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 11146.5308
Deduct 648 from 700 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.

Step 11:
If we divide 520 by 81, we get 6 and a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 11146.53086
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.

Step 12:
81 can be fit into 340 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 11146.530864
Deduct 324 from 340 and we're left 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.

Moving on to step 13:
160 divided by 81 is 1 with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 11146.5308641
If we subtract 81 from 160, we get 79.
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 14:
81 can be fit into 790 9 times, resulting in a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 11146.53086419
The remainder is 61 after subtracting 729 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 11146.53086419 with a remaining 6.1e-08.
