We divide 66601231 by 859
Our goal is to divide 66601231 by 859.

Moving on to step 1:
When dividing 6 by 859, we get 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.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 859

Advancing to step 2:
66 divided by 859 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 859

Advancing to step 3:
The number 859 fits into 666 0 times, leaving a remainder of 666.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 666 after subtracting 0 from 666.
Bring next digit (0) of the dividend behind the 666 and repeat the process: 6660 / 859

Step 4:
If we divide 6660 by 859, we get 7 and a remainder of 647.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 647 after subtracting 6013 from 6660.
Grab the next digit (1) from the dividend, add it to 647, then carry on: 6471 / 859

On to step 5:
The number 859 fits into 6471 7 times, leaving a remainder of 458.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtracting 6013 from 6471 leaves us with 458.
Append the next digit (2) from the dividend to 458 and continue with: 4582 / 859

Going ahead to step 6:
859 goes into 4582 5 times with a remainder of 287.
Use 5 as the next digit of our solution. 
Result so far: 775.0
Subtract 4295 from 4582 to get 287.
Fetch the next digit (3) from the dividend, attach it to 287 and continue: 2873 / 859

Moving on to step 7:
859 goes into 2873 3 times with a remainder of 296.
Record the quotient 3 as the next digit in the result. 
Result so far: 7753.0
If we subtract 2577 from 2873, we get 296.
Take the next digit (1) from the dividend and append it to 296, then repeat: 2961 / 859

Advancing to step 8:
859 goes into 2961 3 times with a remainder of 384.
The number 3 becomes the next digit in our result. 
Result so far: 77533.0
Subtracting 2577 from 2961 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 9:
If we divide 3840 by 859, we get 4 and a remainder of 404.
Use 4 as the next digit of our solution. 
Result so far: 77533.4
If we take 3436 away from 3840, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

On to step 10:
859 can be fit into 4040 4 times, resulting in a remainder of 604.
Use 4 as the next digit of our solution. 
Result so far: 77533.44
If we take 3436 away from 4040, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

In conclusion, the division gives 77533.44 with a balance of 0.604.
