Let's divide 64587945 by 837
We're looking to find how many times 837 goes into 64587945.

Step 1:
The number 837 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 837

On to step 2:
837 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 837

Step 3:
When dividing 645 by 837, we get 0 with a remainder of 645.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 645 to get 645.
Fetch the next digit (8) from the dividend, attach it to 645 and continue: 6458 / 837

Going ahead to step 4:
If we divide 6458 by 837, we get 7 and a remainder of 599.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 5859 from 6458 to get 599.
Fetch the next digit (7) from the dividend, attach it to 599 and continue: 5997 / 837

On to step 5:
The number 837 fits into 5997 7 times, leaving a remainder of 138.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we subtract 5859 from 5997, we get 138.
Take the next digit (9) from the dividend and append it to 138, then repeat: 1389 / 837

Moving on to step 6:
837 goes into 1389 1 times with a remainder of 552.
Put 1 as the next digit of the answer. 
Result so far: 771.0
The remainder is 552 after subtracting 837 from 1389.
Take the next digit (4) from the dividend and append it to 552, then repeat: 5524 / 837

On to step 7:
837 goes into 5524 6 times with a remainder of 502.
Use 6 as the next digit of our solution. 
Result so far: 7716.0
Deduct 5022 from 5524 and we're left with 502.
Take the next digit (5) from the dividend and append it to 502, then repeat: 5025 / 837

Moving on to step 8:
The number 837 fits into 5025 6 times, leaving a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 77166.0
Subtracting 5022 from 5025 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
837 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 77166.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
300 divided by 837 is 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 77166.0
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 77166.0, with a leftover of 0.3.
