64860507 divided by 849 
Our goal is to divide 64860507 by 849.

Going ahead to step 1:
6 divided by 849 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 849

Moving on to step 2:
The number 849 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 849

Going ahead to step 3:
The number 849 fits into 648 0 times, leaving a remainder of 648.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 648, we get 648.
Include the next digit (6) from the dividend after 648, then repeat: 6486 / 849

On to step 4:
849 goes into 6486 7 times with a remainder of 543.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 5943 from 6486, we get 543.
Bring next digit (0) of the dividend behind the 543 and repeat the process: 5430 / 849

On to step 5:
5430 divided by 849 is 6 with a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtracting 5094 from 5430 leaves us with 336.
Grab the next digit (5) from the dividend, add it to 336, then carry on: 3365 / 849

On to step 6:
If we divide 3365 by 849, we get 3 and a remainder of 818.
Put 3 as the next digit of the answer. 
Result so far: 763.0
Subtracting 2547 from 3365 leaves us with 818.
Take the next digit (0) from the dividend and append it to 818, then repeat: 8180 / 849

Step 7:
The number 849 fits into 8180 9 times, leaving a remainder of 539.
The number 9 becomes the next digit in our result. 
Result so far: 7639.0
The remainder is 539 after subtracting 7641 from 8180.
Append the next digit (7) from the dividend to 539 and continue with: 5397 / 849

On to step 8:
When dividing 5397 by 849, we get 6 with a remainder of 303.
Record the quotient 6 as the next digit in the result. 
Result so far: 76396.0
If we subtract 5094 from 5397, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Step 9:
When dividing 3030 by 849, we get 3 with a remainder of 483.
Put 3 as the next digit of the answer. 
Result so far: 76396.3
If we take 2547 away from 3030, we end up with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Moving on to step 10:
4830 divided by 849 is 5 with a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 76396.35
Deduct 4245 from 4830 and we're left with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Step 11:
849 can be fit into 5850 6 times, resulting in a remainder of 756.
The number 6 becomes the next digit in our result. 
Result so far: 76396.356
If we take 5094 away from 5850, we end up with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Advancing to step 12:
The number 849 fits into 7560 8 times, leaving a remainder of 768.
The number 8 becomes the next digit in our result. 
Result so far: 76396.3568
Subtracting 6792 from 7560 leaves us with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Advancing to step 13:
When dividing 7680 by 849, we get 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 76396.35689
Subtracting 7641 from 7680 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 14:
The number 849 fits into 390 0 times, leaving a remainder of 390.
The next digit of our result is 0. 
Result so far: 76396.35689
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 15:
When dividing 3900 by 849, we get 4 with a remainder of 504.
Record the quotient 4 as the next digit in the result. 
Result so far: 76396.3568904
If we take 3396 away from 3900, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 16:
849 can be fit into 5040 5 times, resulting in a remainder of 795.
Use 5 as the next digit of our solution. 
Result so far: 76396.35689045
Deduct 4245 from 5040 and we're left with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

In conclusion, the division gives 76396.35689045 with a balance of 7.95e-07.
