We look at the division of 617140 by 81 
We're looking to find how many times 81 goes into 617140.

Step 1:
When dividing 6 by 81, we get 0 with 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.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 81

Advancing 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
The remainder is 61 after subtracting 0 from 61.
Fetch the next digit (7) from the dividend, attach it to 61 and continue: 617 / 81

Step 3:
The number 81 fits into 617 7 times, leaving a remainder of 50.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 567 from 617 to get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 81

Advancing to step 4:
When dividing 501 by 81, we get 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 486 from 501 to get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 81

Moving on to step 5:
81 can be fit into 154 1 times, resulting in a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 761.0
If we take 81 away from 154, we end up with 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 81

Advancing to step 6:
If we divide 730 by 81, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 7619.0
Deduct 729 from 730 and we're left with 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 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7619.0
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.

Let's proceed to step 8:
81 goes into 100 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 7619.01
Deduct 81 from 100 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On 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: 7619.012
The remainder is 28 after subtracting 162 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
81 can be fit into 280 3 times, resulting in a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 7619.0123
Deduct 243 from 280 and we're left 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.

Advancing to step 11:
370 divided by 81 is 4 with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 7619.01234
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 12:
When dividing 460 by 81, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 7619.012345
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
81 goes into 550 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 7619.0123456
Deduct 486 from 550 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
640 divided by 81 is 7 with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 7619.01234567
Subtract 567 from 640 to get 73.
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 7619.01234567, and the remainder is 7.3e-08.
