Let's divide 66128117 by 839
We want to divide 66128117 by 839.

Going ahead to step 1:
The number 839 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 839

On to step 2:
839 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 839

Let's proceed to step 3:
839 goes into 661 0 times with a remainder of 661.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 661, we end up with 661.
Bring next digit (2) of the dividend behind the 661 and repeat the process: 6612 / 839

Moving on to step 4:
If we divide 6612 by 839, we get 7 and a remainder of 739.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 5873 from 6612 leaves us with 739.
Grab the next digit (8) from the dividend, add it to 739, then carry on: 7398 / 839

Let's proceed to step 5:
7398 divided by 839 is 8 with a remainder of 686.
The next digit of our result is 8. 
Result so far: 78.0
If we subtract 6712 from 7398, we get 686.
Fetch the next digit (1) from the dividend, attach it to 686 and continue: 6861 / 839

Moving on to step 6:
839 can be fit into 6861 8 times, resulting in a remainder of 149.
Write down 8 as next digit of the result. 
Result so far: 788.0
Subtracting 6712 from 6861 leaves us with 149.
Append the next digit (1) from the dividend to 149 and continue with: 1491 / 839

Going ahead to step 7:
If we divide 1491 by 839, we get 1 and a remainder of 652.
Record the quotient 1 as the next digit in the result. 
Result so far: 7881.0
Subtracting 839 from 1491 leaves us with 652.
Fetch the next digit (7) from the dividend, attach it to 652 and continue: 6527 / 839

Advancing to step 8:
839 can be fit into 6527 7 times, resulting in a remainder of 654.
Use 7 as the next digit of our solution. 
Result so far: 78817.0
The remainder is 654 after subtracting 5873 from 6527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Advancing to step 9:
839 can be fit into 6540 7 times, resulting in a remainder of 667.
Write down 7 as next digit of the result. 
Result so far: 78817.7
The remainder is 667 after subtracting 5873 from 6540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

On to step 10:
6670 divided by 839 is 7 with a remainder of 797.
The next digit of our result is 7. 
Result so far: 78817.77
If we subtract 5873 from 6670, we get 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Our division results in 78817.77 with a remaining 0.797.
