Let's divide 70230661 by 543
We want to divide 70230661 by 543.

Moving on to step 1:
543 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 543

Step 2:
If we divide 70 by 543, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 543

On to step 3:
543 can be fit into 702 1 times, resulting in a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 543 from 702 to get 159.
Include the next digit (3) from the dividend after 159, then repeat: 1593 / 543

Moving on to step 4:
The number 543 fits into 1593 2 times, leaving a remainder of 507.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1086 from 1593, we get 507.
Append the next digit (0) from the dividend to 507 and continue with: 5070 / 543

Let's proceed to step 5:
If we divide 5070 by 543, we get 9 and a remainder of 183.
Write down 9 as next digit of the result. 
Result so far: 129.0
If we subtract 4887 from 5070, we get 183.
Append the next digit (6) from the dividend to 183 and continue with: 1836 / 543

Moving on to step 6:
If we divide 1836 by 543, we get 3 and a remainder of 207.
Write down 3 as next digit of the result. 
Result so far: 1293.0
Deduct 1629 from 1836 and we're left with 207.
Include the next digit (6) from the dividend after 207, then repeat: 2076 / 543

Step 7:
The number 543 fits into 2076 3 times, leaving a remainder of 447.
Record the quotient 3 as the next digit in the result. 
Result so far: 12933.0
Subtracting 1629 from 2076 leaves us with 447.
Append the next digit (1) from the dividend to 447 and continue with: 4471 / 543

Going ahead to step 8:
543 can be fit into 4471 8 times, resulting in a remainder of 127.
The next digit of our result is 8. 
Result so far: 129338.0
The remainder is 127 after subtracting 4344 from 4471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 9:
543 can be fit into 1270 2 times, resulting in a remainder of 184.
Put 2 as the next digit of the answer. 
Result so far: 129338.2
Subtracting 1086 from 1270 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 10:
The number 543 fits into 1840 3 times, leaving a remainder of 211.
Record the quotient 3 as the next digit in the result. 
Result so far: 129338.23
Subtracting 1629 from 1840 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 11:
If we divide 2110 by 543, we get 3 and a remainder of 481.
Put 3 as the next digit of the answer. 
Result so far: 129338.233
If we subtract 1629 from 2110, we get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Our division results in 129338.233 with a remaining 0.0481.
