6543097 ÷ 519 
We want to figure out the number of times 6543097 can be divided by 519.

Moving on to step 1:
If we divide 6 by 519, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 519

Advancing to step 2:
65 divided by 519 is 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 519

Going ahead to step 3:
519 can be fit into 654 1 times, resulting in a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 519 from 654, we get 135.
Append the next digit (3) from the dividend to 135 and continue with: 1353 / 519

On to step 4:
If we divide 1353 by 519, we get 2 and a remainder of 315.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1038 from 1353, we get 315.
Take the next digit (0) from the dividend and append it to 315, then repeat: 3150 / 519

Let's proceed to step 5:
If we divide 3150 by 519, we get 6 and a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtracting 3114 from 3150 leaves us with 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 519

On to step 6:
519 goes into 369 0 times with a remainder of 369.
Put 0 as the next digit of the answer. 
Result so far: 1260.0
The remainder is 369 after subtracting 0 from 369.
Bring next digit (7) of the dividend behind the 369 and repeat the process: 3697 / 519

Let's proceed to step 7:
The number 519 fits into 3697 7 times, leaving a remainder of 64.
Write down 7 as next digit of the result. 
Result so far: 12607.0
Subtract 3633 from 3697 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
If we divide 640 by 519, we get 1 and a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 12607.1
Deduct 519 from 640 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 9:
If we divide 1210 by 519, we get 2 and a remainder of 172.
Use 2 as the next digit of our solution. 
Result so far: 12607.12
If we take 1038 away from 1210, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 10:
519 goes into 1720 3 times with a remainder of 163.
Record the quotient 3 as the next digit in the result. 
Result so far: 12607.123
Deduct 1557 from 1720 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 11:
The number 519 fits into 1630 3 times, leaving a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 12607.1233
Deduct 1557 from 1630 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final outcome is 12607.1233, with a leftover of 0.00073.
