69021246 ÷ 543 
Let's see how many times 543 fits into 69021246.

Going ahead to step 1:
543 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 543

Step 2:
When dividing 69 by 543, we get 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 543

Let's proceed to step 3:
When dividing 690 by 543, we get 1 with a remainder of 147.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 147 after subtracting 543 from 690.
Append the next digit (2) from the dividend to 147 and continue with: 1472 / 543

Step 4:
The number 543 fits into 1472 2 times, leaving a remainder of 386.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 1086 from 1472 to get 386.
Include the next digit (1) from the dividend after 386, then repeat: 3861 / 543

Moving on to step 5:
When dividing 3861 by 543, we get 7 with a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 3801 from 3861, we get 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 543

Step 6:
When dividing 602 by 543, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 1271.0
Subtract 543 from 602 to get 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 543

Moving on to step 7:
543 goes into 594 1 times with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 12711.0
Subtracting 543 from 594 leaves us with 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 543

Step 8:
543 can be fit into 516 0 times, resulting in a remainder of 516.
Write down 0 as next digit of the result. 
Result so far: 127110.0
The remainder is 516 after subtracting 0 from 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 9:
If we divide 5160 by 543, we get 9 and a remainder of 273.
Write down 9 as next digit of the result. 
Result so far: 127110.9
Deduct 4887 from 5160 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Advancing to step 10:
543 goes into 2730 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 127110.95
If we take 2715 away from 2730, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
543 can be fit into 150 0 times, resulting in a remainder of 150.
The next digit of our result is 0. 
Result so far: 127110.95
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 12:
The number 543 fits into 1500 2 times, leaving a remainder of 414.
The number 2 becomes the next digit in our result. 
Result so far: 127110.9502
If we take 1086 away from 1500, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 13:
The number 543 fits into 4140 7 times, leaving a remainder of 339.
Write down 7 as next digit of the result. 
Result so far: 127110.95027
Deduct 3801 from 4140 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 14:
When dividing 3390 by 543, we get 6 with a remainder of 132.
The next digit of our result is 6. 
Result so far: 127110.950276
Subtracting 3258 from 3390 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 15:
If we divide 1320 by 543, we get 2 and a remainder of 234.
The number 2 becomes the next digit in our result. 
Result so far: 127110.9502762
The remainder is 234 after subtracting 1086 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 16:
The number 543 fits into 2340 4 times, leaving a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 127110.95027624
If we take 2172 away from 2340, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 127110.95027624, with a leftover of 1.68e-07.
