Let's divide 619215 by 81
We want to divide 619215 by 81.

Step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 81

Moving on to step 2:
81 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Fetch the next digit (9) from the dividend, attach it to 61 and continue: 619 / 81

Step 3:
81 can be fit into 619 7 times, resulting in a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 567 from 619 to get 52.
Bring next digit (2) of the dividend behind the 52 and repeat the process: 522 / 81

Moving on to step 4:
The number 81 fits into 522 6 times, leaving a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 486 from 522, we get 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 81

Step 5:
361 divided by 81 is 4 with a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 764.0
The remainder is 37 after subtracting 324 from 361.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 81

Going ahead to step 6:
When dividing 375 by 81, we get 4 with a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 7644.0
If we subtract 324 from 375, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
81 goes into 510 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 7644.6
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
81 goes into 240 2 times with a remainder of 78.
The next digit of our result is 2. 
Result so far: 7644.62
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
The number 81 fits into 780 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 7644.629
Subtract 729 from 780 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 10:
The number 81 fits into 510 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 7644.6296
Subtract 486 from 510 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
If we divide 240 by 81, we get 2 and a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 7644.62962
If we take 162 away from 240, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 12:
If we divide 780 by 81, we get 9 and a remainder of 51.
The next digit of our result is 9. 
Result so far: 7644.629629
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 13:
81 goes into 510 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 7644.6296296
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
81 goes into 240 2 times with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 7644.62962962
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The quotient of the division is 7644.62962962, and the remainder is 7.8e-08.
