We're dividing 611813 by 81 
We're looking to find how many times 81 goes into 611813.

On to step 1:
When dividing 6 by 81, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 81

Step 2:
81 goes into 61 0 times with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 81

Advancing to step 3:
611 divided by 81 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 567 away from 611, we end up with 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 81

Step 4:
If we divide 448 by 81, we get 5 and a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we subtract 405 from 448, we get 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 81

On to step 5:
81 goes into 431 5 times with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 755.0
Subtract 405 from 431 to get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 81

Step 6:
The number 81 fits into 263 3 times, leaving a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 7553.0
Deduct 243 from 263 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
81 can be fit into 200 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 7553.2
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
380 divided by 81 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 7553.24
If we take 324 away from 380, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
81 can be fit into 560 6 times, resulting in a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 7553.246
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
81 goes into 740 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 7553.2469
Subtract 729 from 740 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
If we divide 110 by 81, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 7553.24691
If we take 81 away from 110, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
The number 81 fits into 290 3 times, leaving a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 7553.246913
If we take 243 away from 290, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
The number 81 fits into 470 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 7553.2469135
Subtracting 405 from 470 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 14:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 7553.24691358
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 7553.24691358 with a remaining 2e-09.
