Let's divide 621610 by 81
Let's see how many times 81 fits into 621610.

On to step 1:
When dividing 6 by 81, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 81

Step 2:
81 can be fit into 62 0 times, resulting in a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 81

Step 3:
621 divided by 81 is 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 567 from 621 leaves us with 54.
Grab the next digit (6) from the dividend, add it to 54, then carry on: 546 / 81

Let's proceed to step 4:
81 goes into 546 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 60 after subtracting 486 from 546.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 81

On to step 5:
81 goes into 601 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 767.0
If we subtract 567 from 601, we get 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 81

On to step 6:
81 goes into 340 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 7674.0
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
81 can be fit into 160 1 times, resulting in a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 7674.1
Subtract 81 from 160 to 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 8:
81 can be fit into 790 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 7674.19
Deduct 729 from 790 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
81 goes into 610 7 times with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 7674.197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 10:
81 can be fit into 430 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 7674.1975
Subtract 405 from 430 to 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.

Step 11:
81 can be fit into 250 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 7674.19753
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
If we divide 70 by 81, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 7674.19753
Subtract 0 from 70 to get 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 13:
81 goes into 700 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 7674.1975308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 14:
81 can be fit into 520 6 times, resulting in a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 7674.19753086
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.

Our division results in 7674.19753086 with a remaining 3.4e-08.
