64537973 divided by 312 
We're looking to find how many times 312 goes into 64537973.

Going ahead to step 1:
When dividing 6 by 312, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 312

Let's proceed to step 2:
If we divide 64 by 312, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 312

Advancing to step 3:
312 can be fit into 645 2 times, resulting in a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 624 from 645 and we're left with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 312

Step 4:
When dividing 213 by 312, we get 0 with a remainder of 213.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 213 leaves us with 213.
Include the next digit (7) from the dividend after 213, then repeat: 2137 / 312

Moving on to step 5:
2137 divided by 312 is 6 with a remainder of 265.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
If we take 1872 away from 2137, we end up with 265.
Fetch the next digit (9) from the dividend, attach it to 265 and continue: 2659 / 312

On to step 6:
When dividing 2659 by 312, we get 8 with a remainder of 163.
The next digit of our result is 8. 
Result so far: 2068.0
If we take 2496 away from 2659, we end up with 163.
Fetch the next digit (7) from the dividend, attach it to 163 and continue: 1637 / 312

Let's proceed to step 7:
1637 divided by 312 is 5 with a remainder of 77.
The next digit of our result is 5. 
Result so far: 20685.0
Subtract 1560 from 1637 to get 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 312

On to step 8:
The number 312 fits into 773 2 times, leaving a remainder of 149.
Write down 2 as next digit of the result. 
Result so far: 206852.0
The remainder is 149 after subtracting 624 from 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 9:
If we divide 1490 by 312, we get 4 and a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 206852.4
If we take 1248 away from 1490, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 10:
When dividing 2420 by 312, we get 7 with a remainder of 236.
Write down 7 as next digit of the result. 
Result so far: 206852.47
If we subtract 2184 from 2420, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 11:
312 goes into 2360 7 times with a remainder of 176.
Write down 7 as next digit of the result. 
Result so far: 206852.477
If we take 2184 away from 2360, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

In conclusion, the division gives 206852.477 with a balance of 0.0176.
