64336987 divided by 617 
We want to figure out the number of times 64336987 can be divided by 617.

Moving on to step 1:
When dividing 6 by 617, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 617

Advancing to step 2:
617 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 617

Advancing to step 3:
617 can be fit into 643 1 times, resulting in a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 617 from 643 to get 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 617

Advancing to step 4:
If we divide 263 by 617, we get 0 and a remainder of 263.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 263 to get 263.
Fetch the next digit (6) from the dividend, attach it to 263 and continue: 2636 / 617

Advancing to step 5:
617 can be fit into 2636 4 times, resulting in a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we take 2468 away from 2636, we end up with 168.
Take the next digit (9) from the dividend and append it to 168, then repeat: 1689 / 617

On to step 6:
If we divide 1689 by 617, we get 2 and a remainder of 455.
Use 2 as the next digit of our solution. 
Result so far: 1042.0
Deduct 1234 from 1689 and we're left with 455.
Fetch the next digit (8) from the dividend, attach it to 455 and continue: 4558 / 617

Going ahead to step 7:
If we divide 4558 by 617, we get 7 and a remainder of 239.
Record the quotient 7 as the next digit in the result. 
Result so far: 10427.0
If we subtract 4319 from 4558, we get 239.
Grab the next digit (7) from the dividend, add it to 239, then carry on: 2397 / 617

Step 8:
2397 divided by 617 is 3 with a remainder of 546.
Use 3 as the next digit of our solution. 
Result so far: 104273.0
If we take 1851 away from 2397, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Step 9:
The number 617 fits into 5460 8 times, leaving a remainder of 524.
Put 8 as the next digit of the answer. 
Result so far: 104273.8
If we subtract 4936 from 5460, we get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 10:
5240 divided by 617 is 8 with a remainder of 304.
Write down 8 as next digit of the result. 
Result so far: 104273.88
Subtract 4936 from 5240 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final outcome is 104273.88, with a leftover of 0.304.
