605420 ÷ 81 
We want to divide 605420 by 81.

Let's proceed to step 1:
81 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 81

On to step 2:
When dividing 60 by 81, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Take the next digit (5) from the dividend and append it to 60, then repeat: 605 / 81

Step 3:
81 goes into 605 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 567 from 605, we get 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 81

Step 4:
If we divide 384 by 81, we get 4 and a remainder of 60.
The next digit of our result is 4. 
Result so far: 74.0
Deduct 324 from 384 and we're left with 60.
Include the next digit (2) from the dividend after 60, then repeat: 602 / 81

Let's proceed to step 5:
The number 81 fits into 602 7 times, leaving a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 747.0
Subtracting 567 from 602 leaves us with 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 81

Going ahead to step 6:
81 goes into 350 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 7474.0
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
81 goes into 260 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 7474.3
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
81 goes into 170 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 7474.32
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
81 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 7474.32
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
81 can be fit into 800 9 times, resulting in a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 7474.3209
If we take 729 away from 800, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 11:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 7474.32098
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
81 goes into 620 7 times with a remainder of 53.
The next digit of our result is 7. 
Result so far: 7474.320987
If we subtract 567 from 620, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 13:
530 divided by 81 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 7474.3209876
Subtracting 486 from 530 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
440 divided by 81 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 7474.32098765
If we take 405 away from 440, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 7474.32098765, with a leftover of 3.5e-08.
