We look at the division of 609121 by 81 
Let's see how many times 81 fits into 609121.

Let's proceed to step 1:
81 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 81

Step 2:
When dividing 60 by 81, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Append the next digit (9) from the dividend to 60 and continue with: 609 / 81

On to step 3:
The number 81 fits into 609 7 times, leaving a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 567 away from 609, we end up with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 81

Advancing to step 4:
If we divide 421 by 81, we get 5 and a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 75.0
Deduct 405 from 421 and we're left with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 81

On to step 5:
81 goes into 162 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 752.0
Deduct 162 from 162 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 81

Advancing to step 6:
81 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 7520.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
81 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7520.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 81, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 7520.01
Subtract 81 from 100 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
81 goes into 190 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 7520.012
If we take 162 away from 190, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
81 can be fit into 280 3 times, resulting in a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 7520.0123
If we take 243 away from 280, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
81 can be fit into 370 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 7520.01234
If we take 324 away from 370, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
The number 81 fits into 460 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 7520.012345
If we subtract 405 from 460, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 13:
When dividing 550 by 81, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 7520.0123456
If we subtract 486 from 550, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
If we divide 640 by 81, we get 7 and a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 7520.01234567
The remainder is 73 after subtracting 567 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The quotient of the division is 7520.01234567, and the remainder is 7.3e-08.
