45680690 divided by 543 
Our goal is to divide 45680690 by 543.

On to step 1:
4 divided by 543 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 543

Let's proceed to step 2:
The number 543 fits into 45 0 times, leaving a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 543

Step 3:
543 goes into 456 0 times with a remainder of 456.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 456 and we're left with 456.
Include the next digit (8) from the dividend after 456, then repeat: 4568 / 543

Step 4:
When dividing 4568 by 543, we get 8 with a remainder of 224.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 4344 from 4568 and we're left with 224.
Bring next digit (0) of the dividend behind the 224 and repeat the process: 2240 / 543

On to step 5:
2240 divided by 543 is 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 2172 from 2240, we get 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 543

On to step 6:
The number 543 fits into 686 1 times, leaving a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 841.0
Subtract 543 from 686 to get 143.
Grab the next digit (9) from the dividend, add it to 143, then carry on: 1439 / 543

Going ahead to step 7:
If we divide 1439 by 543, we get 2 and a remainder of 353.
Record the quotient 2 as the next digit in the result. 
Result so far: 8412.0
If we take 1086 away from 1439, we end up with 353.
Grab the next digit (0) from the dividend, add it to 353, then carry on: 3530 / 543

Step 8:
When dividing 3530 by 543, we get 6 with a remainder of 272.
The next digit of our result is 6. 
Result so far: 84126.0
Subtracting 3258 from 3530 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 9:
543 can be fit into 2720 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 84126.5
Subtracting 2715 from 2720 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 543 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 84126.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
When dividing 500 by 543, we get 0 with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 84126.5
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 84126.5 with a remaining 0.05.
