64137543 ÷ 310 
Let's see how many times 310 fits into 64137543.

Moving on to step 1:
6 divided by 310 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 310

Step 2:
310 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 310

Step 3:
The number 310 fits into 641 2 times, leaving a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 620 away from 641, we end up with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 310

Let's proceed to step 4:
When dividing 213 by 310, we get 0 with a remainder of 213.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 213, we end up with 213.
Take the next digit (7) from the dividend and append it to 213, then repeat: 2137 / 310

Going ahead to step 5:
When dividing 2137 by 310, we get 6 with a remainder of 277.
Put 6 as the next digit of the answer. 
Result so far: 206.0
Subtract 1860 from 2137 to get 277.
Bring next digit (5) of the dividend behind the 277 and repeat the process: 2775 / 310

Let's proceed to step 6:
The number 310 fits into 2775 8 times, leaving a remainder of 295.
The number 8 becomes the next digit in our result. 
Result so far: 2068.0
The remainder is 295 after subtracting 2480 from 2775.
Bring next digit (4) of the dividend behind the 295 and repeat the process: 2954 / 310

Let's proceed to step 7:
If we divide 2954 by 310, we get 9 and a remainder of 164.
Use 9 as the next digit of our solution. 
Result so far: 20689.0
Subtracting 2790 from 2954 leaves us with 164.
Append the next digit (3) from the dividend to 164 and continue with: 1643 / 310

Going ahead to step 8:
310 can be fit into 1643 5 times, resulting in a remainder of 93.
Record the quotient 5 as the next digit in the result. 
Result so far: 206895.0
If we take 1550 away from 1643, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 9:
310 goes into 930 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 206895.3
If we subtract 930 from 930, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 310 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 206895.3
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 310 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 206895.3
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 206895.3 with a remaining 0.0.
