Let's divide 643161 by 27
Let's see how many times 27 fits into 643161.

Advancing to step 1:
6 divided by 27 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 27

Going ahead to step 2:
64 divided by 27 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 54 from 64, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 27

Going ahead to step 3:
103 divided by 27 is 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 81 from 103, we get 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 27

Moving on to step 4:
27 goes into 221 8 times with a remainder of 5.
The next digit of our result is 8. 
Result so far: 238.0
Deduct 216 from 221 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 27

Let's proceed to step 5:
The number 27 fits into 56 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2382.0
Subtract 54 from 56 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 27

Moving on to step 6:
When dividing 21 by 27, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 23820.0
Subtract 0 from 21 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
When dividing 210 by 27, we get 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 23820.7
The remainder is 21 after subtracting 189 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
The number 27 fits into 210 7 times, leaving a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 23820.77
Deduct 189 from 210 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 23820.77 with a remainder of 0.021.
